[@machdaddy6451]

Absolutely! Makes beginers look like pros.

[@wjrneo2]

But only the good techs. Also, you should keep the old release isos around for just this purpose. Aka 1909, 20h1, 22h2. You want to use the iso that matches your installed release version. A command I love to frequently run on a confirmed good running system is the component cleanup command with the reset base switch. Just remember that after it’s been run you can’t uninstall any previously installed updates. So no rollbacks. Windows has a default scheduled task that executes this command, but without the ResetBase switch. Dism.exe /online /Cleanup-Image /StartComponentCleanup /ResetBase

Hold shift while clicking restart, when recovery starts click advanced, command and run sfc in there because inside windows 11 files in use cannot be replaced while in use, sfc via recovery restores ALL sys files That's the proper way to run sfc effectively -_-

Brother I’ve been watching the damn sfc /scannow videos literally ALL DAY LONG!!!! And every single time I did the SFC it would say corrupted files were detected but not all of them could be repaired and I was at a lose till I found this video!!!! I did ALL of the DISM steps and after the last one of RestoreHealth it said it was complete so I ran the scannow command AAAAAAGAIN!! And it said ALL corrupt files were found and repaired!!!! THANK YOU SOOOOO MUCH MY GUY!!

[@wilhelmsarasalo3546]

One time at a client's I started with sfc /scannow. It found no problems. Yet, what had been wrong was working after that. So, that one time I had an opposite problem from what you described. Thanks for putting all that stuff to one place. You were highly informative and I subscribed.

[@SpaceCadet4Jesus]

I get that sometimes too. Barely do anything and the issue mysteriously fixes itself. The customer asks "What did you do to fix it?" Me: 🤷‍♂️🤷‍♀️🤷 Or Me: I say, "It took one look at me and said "Aw Shite, it's him. Quick, start working" 😄

[@MacGuffin1]

was that in 2012? it does nothing these days

[@kuromiLayfe]

the newer version of sfc /scannow only reports if there was an error if it actually is a system critical error.. so system file corruption that do not cause bsod’s are no longer reported unless you use verbose flags

[@matheusgabry2113]

Me too. My Start Menu and all Metro style apps were not working on my W10 out of nowhere, and no amount of restarts were fixing that. I ran sfc /scannow and it found no errors, but after the procedure the Start Menu and all Metro apps were working again.

[@_K.A.R.]

@@MacGuffin1 for me I can say that I had this kind of "magic" last year with an Windows 10 21H2, BUT around 2 month later (after daily usage with ~10hours a day) same Problem was there again (System-restarts out of nowhere). After that nothing (SFC / DISM / inplace-upgrade / driver clean and update / etc.) helped and I needed to reinstall the system. Then all worked fine for arount 4-5 weeks and everything began again. Since it is a custom install Image (on around 100 working systems) it have to be an hardware issue and I replaced the system. All working finde now for around 5 months. Checking the intel NUC (RAM, SSD, add-In card, turn off multithreading and/or turbo boost and of course dust clean, paste replacement) it have to be an defective motherboard. in short that "magics" happen some times BUT they might point to a bigger problem in future.

Just wanted to give you a HUGE thanks for this video. I have an older (2009) HP laptop that has tools and utilities I can't get any longer so I cannot afford to format and reinstall. It became essentially unusable as even at idle it would be running 99% CPU and 8Gb RAM at 60°C+ temps even though it was literlaly doing nothing. SFC never helped at all. No amount of looking into this gave me the answers, although I suspect I wasn't searching using correct terminology to narrow it down. I was just about to give up and accept defeat when I found this.

Excellent video. I've been using windows since the beginning when it was essentially only a crude graphic overlay on top of DOS. Having gone through Win 95 and 98 etc. I was at a point where I created a clone of a fresh install and would revert to that every year or so as the computer became less responsive over time. So yeah, I became a sledgehammer guy. 😁 Old habits are hard to break. I built my current main rig a couple years ago and was considering breaking out the hammer. I'll put that on hold while I await your videos that further explore this topic. After running the "RestoreHealth" on my cache files, SFC found several files/directories "is owned twice or has its security set twice". It also found one DLL file with a hash mismatch and replace the bad file with the new version from cache. An idea for this series (though I'm guessing you already have it on the list) is to talk about the various utility programs out there that profess to be the "be all / end all", "must have" program to keep your computer at tipity top condition.

Another excellent tutorial. As someone who's experience goes back to GW Basic and MS-DOS, we understand that Windows is simply a Graphical User Interface; to make using a computer easier for everyone, novice to pro, but when the GUI gets wonky, it sometimes takes DOS commands to sort it out.

[@d0h]

Solid walkthrough for DISM repairs, but for anyone that needs youtube videos to teach them it's honestly easier with the modern windows to use the media creation tool and do an in-place upgrade of windows (Select Upgrade Now -> Keep my programs and files) instead of saving the ISO. In my experience it repairs everything that DISM/SFC will ever fix, plus uses an offline Defender to scan and remove any malicious changes to the OS.

[@javierchik]

Excellent and very well explained, very helpful, I am already making a notepad to put all the commands in a folder on the network so that I have them at hand. Some ideas for other videos you could make would also be about repairing the Windows boot when it cannot be repaired on its own, explaining bootrec, fixboot, fixmbr, etc., and also how to clone Windows to a new desktop with different hardware where Windows cannot always do it by itself and it sends you the message "no boot device found, please install boot device and try again". I haven't seen any normal videos that explain how to clone to a new desktop with different hardware and an NVMe disk."

[@ApolloTheDerg]

I turned the restore health and sfc into a bat file, it’s been super handy, all I do is run it as administrator and it’s part of my quarterly computer maintenance for a small company, kept the same install of windows on these systems for years with minimal headaches this way, often catches small issues early and quickly sorts them out.

[@eric-.]

oh, man, you got SO close to the whole enchilada. the one thing you left off, and the most important thing - do a full chkdsk before dism repair! First - mega props for getting the word about DISM repair out there. As an IT pro, I've only ever come across a few other techs that even know about it. Now, While you are NOT wrong about out-of-date system file cache, the FAR more common issue is corrupted file system. Here is the full process: open admin cmd/powershell/terminal, then type " chkdsk c: /f /r " (no quotes) ,answer Y when it asks if you want to run at next reboot. Then reboot. chkdsk will scan and repair file system errors before Windows loads. *CHKDSK MUST NOT BE INTERRUPTED* or you could face total system loss. After chkdsk finishes, then Windows will load as normal, THEN do all the _excellent_ steps outlined in this video.

Great video as always. There is probably an extra step I would add to this process. chkdsk C: /F /scan Then I would do the DISM line Then finally the SFC line A lot of the issues I have found is also with corruption in the file system which probably should be repaired first before trying to repair the corrupted files as they might get corrupted again.

[@SpaceCadet4Jesus]

I'd change the order a bit, ALWAYS check hardware first ! No amount of software will fix bad hardware and you shouldn't let software do a damn thing until you've analyzed the situation. Check the drive condition, sector response test, Smart data, etc.. Replace it if broke or breaking. Only then.... R/click the drive for a diskscan (no /F) [the computer can seriously destroy good files if it encounters an unknown situation.) I want to know the state of the file system before I decide what needs to be done. When drive is replaced, run SFC /scannow. If it fixes corrupt data, then good, you're done. If it can't fix, reboot and try SFC again. If still messed up, then run DISM. Other intervening steps are missing cause I'm single finger typing this out on a 8" tablet.

[@CyberCPU]

That's a great point. However, I would use chkdsk /s c: But your way I'm sure works too.

[@David_Ladd]

@@CyberCPU very true. Though normally chkdsk wants you to reboot anyway when dealing with drive C: so at least a good point to grab a coffee or a soda pop while you wait :D Besides, each tech has their way of doing things. Normally what works best for them as long as the customer is best served.

[@David_Ladd]

@@SpaceCadet4Jesus , True, but here is also a good thing to keep in mind. One of the things I use to do back when I was full time service tech was as soon as system came in was check to see if the boot drive was at least accessible. If so then use Symantec Ghost or equivalent HDD backup software and image the drive so at least the original state can be preserved. If the drive had important data on it and they were willing pay for professional data recovery would send the drive off. If the customer couldn't afford data recovery and they were willing to risk it then would use SpinRight to attempt to repair the drive. Sadly a lot of people aren't willing to spend a lot of labor time trying to fix problems and would rather take shortest route to getting the system back up and running. So normally meant if the drive was still good they would opt for the choice of wipe the drive and do a full clean install of the OS they were using.

[@SpaceCadet4Jesus]

@@David_Ladd Like you, I still image all/most of the drives I work on but I ask the customer if I can save it. After the repair, I reimage and save it in an encrypted NAS. It has saved the day way too many times for future problems. I have somewhere between 75TB and 100TB of storage space, of course not all allocated to clients. As for Spinright, somewhere in old pile of diskettes I think I have Steve's original disk. That takes me back to when Steve, myself and others not remembered used to chat over FidoNet. Ever heard of Mace Utilities? It was way better than Spinright or Norton tools. Talked with Paul Mace on the phone trying to get working with him to promote his product more.

It's a balancing act, based largely on knowledge capture of known -vs- new issues/fixes. Turn-around time determines the best approach. * IF * you * KNOW * you can use SFC / DISM / other tools to fix or restore a known issue, and you know that is the ONLY issue, go for it. However, there is another side of the scale to consider... In the enterprise when it takes you 1 hour to backup, re-image, and restore a user's desktop, it may be FAR more time effective to do that. You could spend HOURS troubleshooting and repairing multiple issues, across multiple service calls, all while impacting end user productivity.

Well, that's just it. It comes down to experience. Historically it's the big box store techs that don't have a lot of experience that tend to wipe systems more often. The argument can be made that this happens more in a corporate environment because the systems don't have as much personal data on them. However, when you're working with consumers saving the OS is a lot more important. Yes, it takes less time to just wipe the operating system and reload it. However you also have to factor in the three on-site trips getting Grandma's scanner to work the way it used to because she can't get used to it and putting the links to her bank and Amazon back on the desktop because you can't figure out how to use the search bar in a browser. 🤣😂 I charge a flat rate in my shop so the customer pays the same whether it takes me an hour or 5 hours. Because I've been doing this for over 20 years I have the experience to be able to still make money with a flat rate. For every computer that takes me 5 hours to fix I have 10 others that I fixed in a half hour and it's all the same flat fee.

I deal mostly with small businesses and most of these users have a ton of customizations and special tools that can take forever to get working on a fresh install. Some examples: An rdp connection to their time clock/HR provider, a VPN connection to their video security provider, A connection to their POS system, QuickBooks, Industry specific software etc. On top of that,the problem often came from something the user recently installed (or updated) and the first thing they will do when I leave is to reinstall that thing. Better to get to the bottom of the problem if possible.

[@TheEvolvingAudioNut]

An idea that dovetails nicely with the topic of fixing a broken windows install is troubleshooting hardware issues. That particular rabbit hole runs deep. An example from my recent experience... Over the past week or so my gaming rig started doing some weird things such as programs suddenly crashing or doing things other than the command I had just given it. Other times it would wink out and do a hard reboot. Running Memtest86 found bad memory. I had all four slots filled with 8GB DIMMS. I checked each one individually and Memtest86 found issues with every one. I was thinking that it would be unlikely in the extreme to have four DIMM fail at once. I was thinking perhaps the mem controller on the MB took a dump. As I had some laying around, I took some spare mem and installed it. No failures were found. Yesterday I bought a pack of mem (2x16GB rather than 4x8GB). My thought is perhaps having tightly packed DIMMS on a hard running gaming rig is not the best thing. So far so good.

[@SpaceCadet4Jesus]

All 4 slots of memory being full has no bearing on the computer operation except if the memory is blocked from air flow, which the memory will accept until it ages. If I had all 4 memory boards showing errors, remove all but one, jot down the faulty addresses of each for comparison, test each memory in a different slot and finally test in another computer if available. Seems like you did a good job and solved your issue. Stranger things have happened.

[@ScoutReaper-zn1rz]

Actually, if you were using all 4 slots and had XMP enabled you might have had a problem because of that. There are cases where the memory controller can't run all 4 slots at the XMP rating as the XMP is technically an overclock and can cause odd behavior/crashes. You did the right thing by resorting to only using 2 slots for RAM.

I'd like to thank you very much for that video you did where you intentionally deleted the boot record only to fix it again in order to show us how to repair it. The bcdboot command helped me in fixing the automatic repair error where my computer froze and could no longer boot into windows 10. I deleted the boot records and then recreated them or something like that with the bcdboot command then the computer came alive with the option to boot into safe mode and them from then on it was a cinch i booted the computer normally entered verifier command again and selected delete all existing settings and now it worls like a charm. Again.My nightmare all started with that blasted verifier command where i selected to check all files on the system partition after which it required a restart. After the restart "preparing automatic repair" kicked in and that blastes freeze screen. Thanks again, really appreciated the help you provided. I never heard of the bcdboot command until i watched your video. Bcdboot command helped me solved the issue i was having.

[@SilentPlain]

I'd first do a S.M.A.R.T.'s parameters check to rule out any HDD/SSD failure, then go on with the commands. In some cases, hardware failures can be a potential problem that can be easily spotted with any proper software designed for it (there are a lot of free options out there), thus saving time figuring out what might be wrong and how to fix it (it takes no more than a few seconds to run a diagnose). Sometimes, BSODs are simply caused by corrupted system files that are stored in bad sectors... Just my "2 cents".

[@SpaceCadet4Jesus]

Hey...what are you doing here?? 🤨 You're too smart giving away your best practice advice. 😄 (I wrote a similar comment in this video). So many repair shops run to software fixes when it's smarter to always check hardware (and faster too). Have you heard the saying?: "If it's a penney for your thoughts and you throw your two cents in, .....then someone .....somewhere ....is making a penney"

Amazing I just ran SFC for the first time ever, I've had my system for years and don't remember the last time I did a reinstall. I was all set to do a reinstall when I came across this video. Thought I would try it and SFC completed successfully and repaired the corrupted files. I lucked out this time.

I'm not a tech but I run tons of programs and software and need to fix things within Windows from time to time. I personally would rather just wipe a broken OS rather than chase down specific files or issues because most times its just faster for me.

[@nikolatesla169]

That's right I'll do the same if it's my computer, but when it's a client's computer and they have a lot of software that I'm going to reinstall and download if I don't have the installers, maybe they lose the activation Keys... They don't want to lose some specific configurations etc etc then I would rather do this fix...

Great video I have always done this process for fixing window 99% of the time fixes windows: 1) sfc /scannow 2) DISM /Online /Cleanup-Image /RestoreHealth 3) sfc /scannow doing step 3 make sure you have fixed it. If not go back to step 2) I like the create iso option never knew that one i guess now the fix percent gone up to 99.5% :)

[@ashryver3605]

Except what to do when DISM RestoreHealth gets stuck at 62.3%? Also whenever I did this after spending time overclocking, 100% of the time so far CheckHealth has always said fine, but then an sfc after will fix corruption (ram oc). DISM randomly stopped working even after sfc said it had no corruption. Then i closed out, and dism just no longer showed progress bars.

[@harmonicdefender]

OK, good tips. I use those tools sometimes on costumer PCs. So just for fun of it, i run sfc /scannow command on my laptop as i watching this video. And as you have guessed it throws an corruption error. So i run it again and the second time everything was fine, no errors. Good video, liked and subscribed :)

[@theultramage]

This is a great tip, that ordinary folks can use to hopefully repair their windows in case of filesystem corruption. The sfc /scannow operation by itself _will_ work if any of the system files have been replaced via normal means. That's because since Vista, everything in Windows and Program Files is hardlinked into WinSxS versioned subfolders, and tracked in catalogs. However, if the unwanted change happens by a direct overwrite of contents or disk corruption, this will not work. Windows will detect that the file checksums don't match the catalog, but will have no clean source to repair from. Here, Microsoft could have done a great thing and implemented a way to automatically obtain this clean source via Windows Update - but for me it never does, even if the source is a windows update patch and the patch is still in the Microsoft Catalog. So instead, you have to provide it yourself. The way outlined in the video, by using the Media Creation Tool will probably work, except... to do the repair, you have to provide the exact versions of the files you're currently using, and the tool does not let you choose the version - iirc it just always downloads the latest released version of the OS. So you might have to hunt the web for forum posts with direct links to specific ISOs. And even that might not be enough, since some files might be from intermediate patches, or from monthly patches newer than the current release ISO. In that case, you need to do power user-level surgery: - Examine Windows\Logs\DISM\dism.log for mentions of files inside WinSxS which report mismatched checksums. - Examine the accompanying lines which mention which KB update package the damaged files belong to. - Download the KB package matching your OS from the Microsoft Catalog. - Unpack it using the builtin 'expand' commandline utility. (Verify version numbers if you need to.) - Overwrite the damaged files in WinSxS with clean ones. (Binary diff them to see the extent of the damage.) - Run sfc /scannow to redeploy the fixed files. As a possible alternative, I'm checking microsoft fwlink LinkId=243077 and it says /Source supports various things, not just wim - a backup image, a SxS folder (on usb or network share). It might even be possible to just point it to the unpacked KB files. If not, you could repair from a mounted backup, or from a C:\ share of another PC or VM that has the same windows version and updates as yours.

[@acsam1]

That is the answer I was waiting for! For successful repair with DISM+SFC you must have clean files of the exact version and that version is not always the latest one. And from my experience DISM never downloads it. And in 99% of situations DISM is used in Recovery mode without network access, because Windows does't boot.

[@AmmoDude]

Thank you, thank you, thank you! My hard drive was spinning, seemingly searching all the time. I ran both sfc and DISM then sfc again and my laptop runs like new again! I saved the info for use later if it starts to act up again.

[@opulentnotes]

Thanks for sharing these cool commands! I've actually been using DISM commands to help fix corrupted files on a customer's PC majority of the time, and usually stop at /restorehealth. I had no idea you could run sfc /scannow afterwards -- I always thought it just was not doing a darn thing so I omitted it out of the process. Definitely will try this process next time 🙂 There was one instance where DISM was loading in CMD and it would get stuck at 64% and not move for several mins to a couple hours (even tried rerunning the command), why is that?

[@glebglub]

my guess is the anti-virus going mental scanning every single file that is being manipulated on a spinning-platter HDD, alongside slow internet speeds as dism is updating files through windows update (which would thence increase how much work the antivirus is doing as it's effectively scanning the same file 3 or more times and communicating with the cloud server about it, depending on your settings). could also be the storage device is way too full so it can't move files around as efficiently (typically ~15% free space is recommened iirc). maybe only 1 stick of RAM operating at minimal frequency, overheating on the CPU as the cooler shifted in transport, especially if it's a heckin' chonker like my NH-D15 (though for these I'd recommend unmounting the cooler as it can damage your motherboard/cpu in transit, at least without that expandable foam stuff SI's use for pre-builts to keep it in place). but I'm no expert, so there may be some other things going on too I'm not aware of, these are just my thoughts without knowing more of the system(s) you were working on

[@opulentnotes]

@@glebglub Thanks dude, this is pretty helpful info as I did not know the anti-virus plays a role in this. I work for a big corporate company, and our company PCs are basically all laptops that have 10th gen and higher CPUs and NVMe M.2 SSDs. Your guess is as good as mine, our machines have McAfee and its tied to group policies to make sure the device is in compliance. The internet connection could be a possibility -- as since covid we use remote connection to troubleshoot machines and requires us to connect to a VPN which tunnels to our company server. We do this in order to elevate admin privs on the user's machine (we need to do this to even access CMD as Admin)

[@albafranco3515]

could you fix this? i also tried option /image instead of online from wimndows cmd in system recovery booting from iso...no luck

[@Vichion]

@@albafranco3515 I dont remember what I did but I remember this text is what helped me ````` The error 0x800f081f in DISM usually indicates that the specified source file couldn't be found or accessed. Here are several steps you can take to troubleshoot and resolve this issue: ### 1. Verify the Path Ensure that the path to the `install.esd` file is correct. Double-check the drive letter and the path to the file. For instance, if the file is on a different drive, make sure to adjust the drive letter accordingly. ### 2. Mount the ESD File You can try mounting the `install.esd` file and then pointing DISM to the mounted location: 1. **Mount the ESD File:** - Open Command Prompt as Administrator. - Run the following command to mount the ESD file to a folder (e.g., `C:\Mount`): ```shell dism /Mount-Image /ImageFile:F:\sources\install.esd /Index:1 /MountDir:C:\Mount ``` 2. **Run DISM with the Mounted Folder:** - Run the DISM command again, pointing to the mounted folder: ```shell dism /Online /Cleanup-Image /RestoreHealth /Source:C:\Mount\windows /LimitAccess ``` ### 3. Use the Correct Index If the ESD file contains multiple images, you might need to specify the correct index. To find out the available indexes, you can list them using: ```shell dism /Get-WimInfo /WimFile:F:\sources\install.esd ``` Use the correct index from the output in the `Mount-Image` command above. ### 4. Ensure Read Permissions Make sure that your user account has sufficient permissions to read the `install.esd` file. Try accessing the file directly in File Explorer to ensure there are no permission issues. ### 5. Alternative Source If the issue persists, you can try using a different source file, such as `install.wim` from a different installation media, and see if that resolves the issue. ### 6. Windows Update Sometimes, ensuring your system is fully updated can help resolve such issues. Run Windows Update to check for and install any available updates. ### 7. Network Source If you're using a network location for the source file, ensure the network path is correct and accessible. Map the network drive and use that path. ### 8. Logs Check the `C:\Windows\Logs\DISM\dism.log` file for more detailed error information, which might give you more clues on what might be wrong. By following these steps, you should be able to identify and resolve the issue with DISM failing to find the source files. `````

Here's another command prompt shortcut: When you have a path in explorer highlighted, just do a to copy the path to your clipboard. Now, while at the command prompt, r-click the command prompt window and it will paste the highlighted address into the prompt. This really saves a lot of time from having to type a long address, and also eliminates typos as well. Hope this helps?

Don't ever be intimidated by the typical "IT" guy. The stuff they know they got from a college course or from word of mouth. I never went to college for IT but had a job in it for over 10 years. It's pretty much just making sure you are keeping up to snuff with your knowledge in the changing landscape. For example this video taught me something I didn't know even though I was in IT for 10+ years (The whole DISM being used to aid in scf /scannow thing). We did do things that a lot of IT didn't do (at least in the midwest) which was using manjaro to re-image machines after cloning the drive and then putting their files back on it. It was much faster than reinstalling Windows the normal way. The only downside was that you had to unregister all drivers and re-install them all.

Downloading DISM alone is confusing enough because it's like 25 separate exe files for your version of windows. SFC on its own never worked, I concur. For corrupted file attributes on a partition shown as RAW, chkdsk /f + permission reset works. Thank you so much for your work and sharing.
