They're not so great at picking up after themselves when they are done. Rebooting cleans up the RAM of all the toys the programs left on the floor."

[@JoePolvino]

Very good explanation of complex concepts. It is unfortunate that we've grown accustomed to operating systems that allow programs/processes to misbehave to the point that a reboot is required. As an IT professional, it is infuriating to be in the middle of a very long task that requires multiple applications, browsers, etc. to be open...only to be forced to reboot. While this probably doesn't bother casual users watching KZbin or browsing as much, there should still be efforts to detect what is causing the need to reboot, and address those without forcing a reboot.

[@BeastinlosersHD]

I know, I find it so odd there isn't a better way (or at least some sort of advanced feature somewhere) that allows the state of programs to be saved between reboots. I know this would probably be a pain, but if I had to wait a bit for RAM to write to storage and then for it to pull it back up, I'd prefer that to having to pull everything back up manually. Obviously this wouldn't help with non OS problems. However, I find my firefox browser is the biggest source of frustration from this. If you forcefully end firefox through task manager, you can restore it later, whether you reboot or not. This lets me keep everything I'm researching pulled up after the reboot (or after I'm done doing something RAM intensive).

[@neilbradley]

@@BeastinlosersHD It's technically possible and has actually been done. PowerPC/WinCE worked this way.

I suspect we don't have the "hibernation per program" in every major OS because the running programs often depend on some external state which wouldn't get saved and would cause the programs to misbehave or crash when brought up the next day.

“Bootstrapping” comes from paradox, which is that you can’t pull yourself up off the ground by pulling on your bootstraps. The paradox of starting computers is that in order to start loading software, a computer needs software to tell it how to load software! Getting around that involves “bootstrap” code. In early machines this bootstrap code was often inserted by hand, using switches to load register contents: the bootstrap paradox was skipped by human intervention. That initial hand-loaded code sometimes started an input device, such as paper tape or card reader, or mag tape, from which the next bootstrap stage could be loaded.

What made the hand entry of that initial bootstrap loader a bit more tolerable was that you didn’t need to do it every time you turned the machine on. The magnetic “core” memories of the time were non-volatile and would keep their contents with the power off, so unless you suffered a really bad software bug that overwrote that part of the RAM, the loader would still be there.

More recently, I found "Auslogic's Disk Defrag" had an option for a similar graphic view. I used it for years. Though the last time I used it.. they started pushing their other software with ads pretty hard. If you can find an older version though it used to have a really simple clean interface.

Fragmentation is one we come along lots in game development. Back in the PSX days we used to have binary overlays between the main menu and the actual game. This was a different binary which was loaded. They both even had different memory managers because the behaviour of the memory allocation was different. It also meant when going into a new game fragmentation was totally wiped out because the memory manager was "rebooted".

[@hakachukai]

Another reason that rebooting sometimes fixes things ( if you're not running ECC RAM ) is memory errors. Yup, even though there is nothing wrong with your RAM and it works fine... it can still in very rare cases accidentally flip a 1 to a 0. If this happens in the Operating system layer ( ring 0 ) it can cause anything from BSD's to slowdowns and memory leaks to straight up broken behavior. The easiest fix is definitely a reboot.

I don't do day to day windows admin work any longer, but while I was, it was EXTREMELY annoying to have to find all the tools I used on a daily basis again every time a new version was released.

Wow !!!! My ears perked up when you said , RingZero .... Due to your background , could you do a video on how in the beginning Windows and OS/2 played together but later on went in different directions . It is my limited understanding , but I was told OS/2 used RingZero differently? What’s the story on how the two operating systems dealt with security and the rings ?

I'd love to see some videos on the registry. I might be the only one though. Love your videos Dave. Keep 'em coming!

[@DavesGarage]

I'd love to, but what would you like to know about it? If there are questions you can think of that'd be a great start!

[@Abhorsen6930]

@@DavesGarage Honestly, I'd like to start with how it's structured. What some of the main group keys mean and translating the names from dev-speak to regular human. One other thing that always had me puzzled, was what was actually stored in the registry in terms of data, and details on why it exists. I have a general understanding of how it functions and maybe a cursory understanding of it's overall purpose in the system architecture but I've never had it explained to me in a way that made a whole lot of sense. Is it just a data structure a la C++, or is it more than that (or perhaps less, just a simple csv or the like). I'd also love to know why the registry tends to bloat as the PC ages. I know part of it is due to uninstalls and not fully clearing data out of the registry (for whatever reason that may be), but that's about all I know about it. As my good friend in IT would say - I know just enough to be dangerous, but with enough sense to know when I'm truly out of my depth (or in other words, a student of computer science). I will sometimes poke around and explore in the registry, and I've pulled keys and stuff out of the registry (that goes back to the days of MSN chat rooms) and I've even completely deleted unnecessary registry entries with the aid of tools meant for that purpose (always with backups!) but never really *understood* the effect it was having on the system. Hoping that my diatribe is helpful.

[@BertGrink]

@@DavesGarage For one thing, *I* would like to know _where_ it keeps its information hidden; is it in a single file or is it scattered about like so many pebbles?

[@eDoc2020]

@@BertGrink That's easy. The registry is made up of a few hives and each is its own file. Most of the hives are in the system32\config directory, and I believe these files (COMPONENTS, SAM, SECURITY, HARDWARE, SYSTEM) are directly loaded as their corresponding entries in HKEY_LOCAL_MACHINE. The user-specific registry entries are stored in the NTUSER.DAT file in each user's profile directory.

Nice Video. Always interesting to watch/hear your open informative discussions from your previous life as Microsoft Engineer. :) :) I used to have a VCR that I swear must have been running Windows Embedded OS. About every 3 months, it would go crazy... Powering Off/On didn't help, because, powering off many devices doesn't actually power them off, they just blank the screen and go into idle mode (a clue is they usually have a clock or some LED lights that stay on...). When it would go nuts (again, about every 3 months), I would physically unplug it for about 10-20 minutes, plug it back in, and then it would run just fine for another 3 months or so.. What fun. :) :)

Hi there! I recall that on older Windows versions, the task manager had an option to kill an entire process tree. This option doesn't seem to exist any longer in my Windows 10 version. Any idea why that changed? To be honest though, I never felt the need to use that option. Killing only the non-responding process always did the trick for me.

[@Perseagatuna]

It does exist in mine, check in the Details tab

[@davidcrawford6505]

As an IT customer support specialist, I really appreciate this explanation. End users can get pretty frustrated when you ask them to reboot. Task manager is a great tool for showing end users what is happening when they complain about system performance. Now if I could just get our end users to login at least monthly to keep their PC on the domain.

[@kencarp57]

Hi Dave! I love your videos! It's awesome to hear from someone who actually wrote part of Windows. Your videos bring back lots of memories - for better or worse... I started in IT way back in 1978, with IBM. I witnessed the entire OS/2 debacle, and subsequent dominance of Windows. IBM made so many blatant mistakes with OS/2 that it's funny now... but it wasn't funny then. Back in 1990-91, I was in technical support group that worked closely with the development group that was engineering a product called OfficeVision/2... IBM's LAN-based office system that provided e-mail, calendars, and contacts, and communicated with Officevision on other IBM platforms. From the very beginning, it was a bloated disaster that never even came close to working in the real world. It had some very interesting functionality such as support for iBM's super-heavyweight Document Content Architecture (DCA) and Document Interchange Architecture (DIA) - but it had so much application code in it that it overwhelmed the modest PC hardware of the time. We were running 286-based machines with 1 MB to 4MB of "extended" RAM, and later 386-based machines with a proper 32-bit machine architecture that enabled the OS to properly manage large memory spaces. Running a gigantic app like OV/2 on the tiny little machines like we had was like trying to pull a train with a pickup truck! So much OV/2 code was loaded, and the application working sets became so large, OS/2 would page to disk like mad, sometimes for the better part of a minute, and sometimes longer than that... while we sat there waiting. It was crazy! There was no defrag utility for the OS/2 High Performance File System (HPFS), so who knows how fragged our disks probably got. We reformatted and reinstalled OS/2 and the OV/2 app MANY times though... I do remember that. Anyway, the OV/2 version that never came out was based on OS/2 and it's newly-developed "Workplace Shell" - a novel object-oriented desktop UI that enabled the user to drag icons around and perform actions with them - like deleting the file by dragging it to the trash can icon, moving or copying it by dropping on another folder icon, or printing by dropping it on a printer icon. The Workplace Shell was pretty slow and unstable back then, and it frequently crashed itself - which required a reboot to get the system back. It had its own version of Task Manager - I don't remember what it was called. Frequently, we would need to use it to kill an errant or hung OV/2 process, but it often didn't work. I remember having a rather stressful conversation with OS/2 development about not being able to force kill a Workplace Shell application process reliably. The conversation went in circles, and the dev guy just couldn't understand why the user should EVER be able to force kill an application process (e.g. a hung e-mail creation window running the OV/2 word processor), because that would lead to "losing the user's data". I kept telling him that if the app process was ALREADY unresponsive, there was no way to "save" the user's data anyway - so the process needed to be force killed to allow OS/2 to reclaim the memory the hung app process was consuming. I just couldn't get him to understand that, and I don't recall if it was ever fixed in OS/2. It turned out the the Workplace Shell didn't work like your WIndows Task Manager did... the Workplace Shell would simply "ask" the application process to terminate, which of course wouldn't work if the app was already unresponsive and not able to service the Workplace Shell's "terminate" API call to it. D'Oh! Round and round we went... Looking back on all that, it's funny now. Due to IBM's unmitigated corporate arrogance with OS/2, it became a ghost OS in a few more years, and eventually just disappeared from the PC world altogether - although it lived on (in infamy?) in some applications buried in other things for quite a few more years - and Windows went on to rule the PC world. Anyway, it's cool to hear from the guy who actually WROTE the Windows Task Manager to do what it needed to do, in the right way, RELIABLY. Nowadays I use an M1 MacBookPro running MacOS Ventura with 32 GB of RAM and a very fast SSD - but MacOS STILL slows down after several days (I have measured the performance of my various apps and verified this slowdown over time), and I have to reboot to restore the performance. The MacOS Activity Monitor never shows that memory is all used up (it never seems to be anywhere near 100%), but the system does measurably slow down over time. I am convinced that there is SOMETHING in MacOS relating to memory management that just doesn't work right, and slows the machine down after several days of use, until a reboot clears all of that out and the machine is fast again. This happened on my previous Intel-based MBPs too, so it isn't an M1 thing. I have Googled the topic ad nauseum, but the only things I've found to resolve the decaying performance over time is to simply reboot. It's maddening that here in 2023, Apple STILL hasn't figured out how to reliably manage system resources like memory (or pointers or SSD file references or whatever) to keep the performance fast over time without the user having to reboot periodically!
