I don’t have to touch the registry often but I’m very happy that I have the option to. Also don’t forget to backup your registry before messing with it !
H in HKEY means "Hive Key"... and those root registry folders are simply the loaded forms of the hives, the files found on several paths in a Windows installation.
My friends and business associates consider me somewhat of a "computer guru", but ThioJoe almost never stops amazing me at his depth of knowledge. I learn a LOT here!
This is a good explanation... It might be worth its own video... but backing up your registry and making a list of favorites inside the registry (and exporting your favorites) could be useful to other power users.
Funny that years ago I would never have thought to touch anything in the registry, I was paranoid to do anything in it for fear of breaking something. Slowly I got more familiar without and learned about it and now I delete, edit and add entries to registry all the time, it really comes in handy to learn about the registry.
As a Linux user who hasn't used Windows since the days of Win98, I'd be interested in knowing more about how it works from a programmatic standpoint as well as how bits of the registry are protected from ordinary users modifying them. Could a user just select the root of the tree and hit delete?
Amazing !! - So clear and direct, in only 6 minutes !! -For the first time in my life, I feel 'safe and curious' in _the registry_. It used to be like >>"F3" and ONLY touch what i'm there for

- 0:40 There actually is a driver/program called RegFS that lets you mount the registry hives as a filesystem so that you can browse and edit them in File Explorer just like actual files. Sadly, it was pretty unstable and didn't support the newer changes to the registry format and was eventually discontinued. 😕 - 3:21 You can use ERUNT to defrag and shrink the registry (like using the _vacuum_ command on SQLite databases). - You didn't mention how the mappings work, that is, how system and user settings override or take precedence when there's a collision.
So Joe mate from this video can I assume that the registry keys are not in one particular place in the OS system and placed apart from within the system? This tutorial is not what I expected and thought that registry had it's own spot in the OS. I think a much simpler assessment of each HKEY for those of us who are not that tech savvy
The Registry was introduced with Windows 95. Before that Windows 3.1 (and 3.0) simply used a couple of .ini files: win.ini system.ini desktop.ini user.ini etc. And they were just simple text files you could open with Windows Notepad. They contained some code-like text but were mostly readable by anyone. Every individual program also made use of its own .ini files as well. It was simple, but far too limited. A more database-like system like the Registry was inevitable.
Now, due to the recent explosions of cyberattacks, how will you know if your HKEY in the registries are good, or potentially harmful, or dangerous? Malwarebytes usually will detect the dangerous HKEY programs if your computer is infected with these bad registries, but can they find all of the bad stuff?
I find your videos either informative or eye-opening, no matter what length they are. But today's video is the perfect length, because of my shortened attention span on this particular day. Must... increase... caffeine... consumption
Interesting video and really good and simple explanation! Have been a fan for a really long time. Keep up the good work man! Also I've always been scared and cautious to enter the registery cuz i thought i was gonna mess my main pc up lol
0:15 I could be wrong here, but according to my experience in database development i think you probably misunderstood something. There are no variables in document databases, but only keys and values. The things on the left are actually just a type of "distribution keys" which are used to organize the data (quite similar to objects in JSON), and the things inside them are the actual keys and their values. For example the "Desktop distribution key" in the "current user root distribution key" could contain a "key" named "AnyRandomBackground" and a string value in side which is a file path (the names could be wrong, but I wrote them just for the understanding). This is a common structure in document databases (for example JSON), and I could recommend you to learn a bit about it, just for the basic understanding. It is very interesting.
I looked up the documentation and I think ThioJoe is right in this case. According to Microsoft's terminology the "keys" on the right side are just called "value names". Search "Structure of the Registry" in Microsoft's docs.
Does anyone know how to fix/restore a missing Regedit key, specifically the one at HKEY_LOCAL_MACHINE\SOFTWARE\Khronos\OpenCL\Vendors ? I need it to enable OpenCL on Premiere Pro.
“If you enjoyed this video”, yes but I literally wish Microsoft had told me this stuff in 1993 not 2023, when they first dumped it on me with Windows NT 3.1. Why has even the basic stuff been such “security by obscurity” from the beginning, or was it more just like laziness?

Yo could you do a video on how to change the transparency of the task bar with a registry edit. I specifically want to make the taskbar completely transparent.
Hey I have an issue where I changed my path environment variables and now when I go to open my VM’s it give me an error file not found at the path location. How can I change my vm path to point to where my ISO are stored on my vm machine?
In my opinion Windows relies way too much on these registry keys for apps other than the OS. I have had to recover dozens of registry files when the user has impatiently held down the on/off button for five seconds and then find out the next morning that their registry is corrupted.
hkey_users won't necessarily show registry data for all users. It depends when the users were last logged in, when the machine was rebooted/reloaded, etc. All these years (decades) I didn't realize there was HKCC. I've always been going to HKLM\system\currentControlSet Then again, HKCC doesn't contain all of CurrentControlSet, and you still have to go to ..\System\CurrentControlSet from HKCC so maybe I'll just stick with what I've been going to.
You did spark a question about users. I bought office online. I am concerned that the controlling email owner may have access to what I do that I don't want them to. Can I read any of these to find out?
HKEY is really just a weird implementation detail with how registry access works in the Win32 API. Win32 's use of hungarian notation for identifiers means everything needs to have its type in the name so the constants to access the root keys all start with HKEY because they are used as handles to the root keys.
I have Win 10 Home Edition and I have several tabs at the top, one of them being the performance tab. ThioJoe's setup is different, guessing he has the Win 10 or Win 11 Pro version. He has a list of icons running down the left side, and he has selected the performance icon (indicated by the blue mark by it).
The registry has become a dumping ground for installed software. When software is uninstalled it may leave behind junk that over time clutteres up the registry with orphaned keys. But unless I can proove that a key is never referenced by any software on my machine I won't delete that key. I don't trust Norton when it tells me I have 2k registry orphans. How would you prove that a registry key is never referenced by any software? I know there are utilities that monitor the install process and record any changes to the registry so that the changes can be undone. But I cant remember the names of any of these utilities
I had to use the registry to fix an issue with my windows profile. For some reason windows logged me a temp profile, but I still access to my user date, but my settings were reset: My desktop, my app settings. (and would reset each reboot). I had to delete a registry setting, change a name of one to .bak, and the change the user profile from temp back to my user profile. (because it auto correct to temp when I deleted the .bak key.) (Bing AI explain it to me.)
That used to happen quite frequently when I did desktop support. Some weeks we'd have a few temp profile issues, and other times we could go months without seeing any. At least they were easy fixes. If someone was patient I could walk them through it at home.

• At 1:55 I mixed up the 'HKU' and 'HKCC' abbreviations

I’ve never actually backed it up, but “my other car is a Mac”, so to speak. I suppose I didn’t care if I crashed the company car.
Make a System Restore Point to be sure. It’s the easiest way to revert to the previous state of Windows.
Or at least back up the key path you’re altering.
I'll take your word and leave the Registry alone. Makes sense, right?
Yep, no need to rummage around in it unless necessary
A tip id recommend to always export the one before modifying anythint incase you felt the app/ device is not functioning properly
@@ThioJoe but what if there is a need to rummage around in it
@@ThioJoe It is not that harmful, just like Linux config files.

Yeah it has individual NT permissions on every key, so you can't do that
Doesn't work. Even if you had the permission. It is actually easier to delete all Linux boot config files than a whole HKEY :)
It looks like navigating to your root directory cd /, then rm -rf
