Yeah, but this is where a lot of people will sternly warn you about messing with the Windows registry if you don't know what you're doing. I won't do that, because I assume you've already heard this and know it's true.

But truth is leftover keys really shouldn't hurt your system the least little bit, and there's probably a WHOLE BUNCH more residual leftover keys you don't notice that are still there not hurting your system.

If it bothers you knowing it's there, I suppose yeah delete it but it really wouldn't be helping anything at all if you get rid of them unless they're causing a cosmetic problem like it's still in add/remove programs because of that but if it isn't causing anything noticeable and you just want to delete it for no real reason, If not just for not wasting my time doing that and doing something a bit more productive with my life even if in the end we're all just wasting our lives away anyways. Still probably something funner you could be doing.

you could, but unused keys will not hurt anything, or slow anything down
registry is extremely efficient, extra keys or entries dont make it any slower

and messing with keys/values/data that is used can easily mess up other things

even using windows or steam uninstall will not remove all the extra registry entries

There is registry cleaning software out there like CCleaner, I guess. They can find unused keys and paths and whatnot though there's no guarantee they'll find everything or even keys to your games It is wise to make a restore point or a system backup with imaging software.

Many say these things are snake oil and make claims that don't pan out. They actually don't improve speed or performance or anything but there is like a palliative effect that it might make you feel better. I run one occasionally just to see what it picks up. Doesn't harm but it doesn't do much else either.

you can manually backup registry, but when you restore, it only adds and changes entries, not removing existing keys

there are commands to remove keys using .reg backup files, but removing stuff thats needed can make windows not bootable and/or lock it up.

if you really want the old game stuffs removed from registry, if you dont know what you are doing, its safer to reinstall windows

! Hook up everything in "Custom Clean" Windows Tab, EXCEPT:
  • Windows Explorer > Network Passwords (un-hook)
  • Advanced > Wipe Free Space (un-hook)
  • Windows Downloads > all (un-hook)

! Hook up everything in "Custom Clean" Applications Tab

! Hook up everything in Registry

! in Options:
  • CCleaner Home Screen > Custom
  • Smart Cleaning > DISABLE
  • Advanced > only hook up >> Skip User Account Control Warning & Enable Jump
  • Privacy > Disable all telemetries .. and stuff


After setting up CCleaner Slim as shown and described above:

  1. > Custom Clean > Analyze > Run Cleaner
    (do this a few times until nothing appears there anymore)

  2. > Registry > Scan for Issues > Review selected Issues... > Fix All Selected Issues
    (do this a few times until nothing appears there anymore)

  3. > Close CCleaner

  4. > WIN+R > cleanmgr.exe
    run in regular mode first, hook up and clean everything ..
    then run as well in admin mode afterwards, hook up and clean everything again !!

I even HIGHLY recommend you do a complete fresh and clean install of your system, if you have run it for years ... afterwards your machine is going to run like on its first day ...

Reformat/reinstall a fresh and clean W10/W11:
Win11: https://www.microsoft.com/software-download/windows11

Win10: https://www.microsoft.com/software-download/windows10

W10/11 Clean Install
https://www.microsoft.com/en-us/windowsinsider/cleaninstall

  1. Plugin your USB with Windows 10/11 install media
  2. Keep your correct IRST drivers ready inside an extra folder, to be save ..
  3. Open Windows Start menu
  4. Restart your PC while holding the Shift key to boot into the Windows Recovery Environment (WinRE). Once in the Windows Recovery Environment, choose to boot from the USB drive.

Once your drives and partitions are ALL deleted & formatted in setup, continue..

During later stage of fresh install, @ Language Selection
  1. cut LAN/WLAN
  2. "Shift + F10" to open console
  3. type:
    oobe\bypassnro
  4. auto-reboots
  5. select:
    "I don't have internet" "Continue with limited setup"
  6. Install your "LOCAL ACCOUNT" and disable all telemetry stuff during setup
    >> Profit


Later you can even setup a PIN in Windows Options without being online/Microsoft account, and if you like - and I suggest it - uninstall Windows OneDrive straight after you enter your freshly installed Windows and disable UAC (User Account Control)!! Afterwards let your machine connect to the internet and use Windows Update and Microsoft Store Apps update.

If updates are done, install AntiVir as "ESET Premium" and "Mozilla Firefox + uBlock Origin" (by Raymond Hill). Then search for more and specific drivers manually, as latest NVIDIA drivers, more special Chipset drivers, latest BIOS firmware, etc ..

Leave them alone.

While it's true that in the past there was a reason to use registry cleaning this point hasn't been valid for many years now.

You get zero performance benefits from cleaning out registry on modern hardware, and on the contrary risk breaking stuff.

Microsoft themselves recommend against cleaning out registry.

The "regular" cleaning features in ccleaner and apps like it are fine though.

Messing about in the registry is VERY DANGEROUS and runs a very high probability of screwing up your computer to the point of making it completely unusable. If you have never touched the registry before and don't know what you're doing then don't touch it now.

its funny that someone ask 1 specific thing and some random tells them to blow up their whole stuff.. internet..

If you know where they are located, no problem, but it won't make a difference, because by default the regestry is already 140MiB and not KiBs.

You can delete unneeded keys. But there's not really any benefit to it. It's more busy-body FUD than anything. And it really depends on your ability to correctly identify unneeded registry keys.

At work a lot of the software we write for internal use relies heavily on registry keys. And I've had to do plenty of registry work over the years to configure servers, like disabling TLS1.0 and 1.1 on our older web servers. The point is, I'm in there a lot for specific purposes. And cleaning up the registry isn't any sort of concern.

And the number of times I've legitimately needed to do anything in the registry on my personal machine in the last decade I can count on one hand. And it has nothing to do with cleaning out orphaned settings. Do it if you want, but don't kid yourself that it's anything more than OCD.

regedit is useful if you want to change specific things for windows ui that ms does not allow in its generic menu setting

and changing file associations, windows icons, run recent list, and startup items/commands
many games use windows registry for setting, or game saves, since that is way faster than data written to drives

but changing something you are unsure of or an incorrect setting can completely break windows and make it unbootable or unresponsive

Ignore the fools who say registry cleaner utilities are unnecessary or harmful.

Though using an uninstaller tool like Revo or BCU that keeps that stuff from accumulating in the first place is better.
plat 31. jan. 2024 kl. 19:19 
Yes, I use a third party uninstaller and as part of the Advanced scan for remnants, it will delete a lot of registry keys. In that case, a dedicated registry cleaner is of no use to me. Maybe some perceive a tangible benefit but I never noticed a difference either way.

I don't condemn anyone who does or doesn't use one though--as long as you're aware of any potential risks. Actually, I find it more risky to manually delete those things. Two false moves and oops!
