[2] How to get Registry Admin Owner & Permissions using Command Prompt:
Download the "
SetACL.exe", copy it where the Command Prompt or Batch file.cmd starts from.
1. Download, (extrat it if it's in .zip) and place it on Desktop.
Then Copy it to C:\Windows\System32 (by cmd or manually)
(eg.:
copy "%UserProfile%\Desktop\SetACL.exe" "%SystemRoot%\System32\SetACL.exe")
2. Open a Command Prompt (as Administrator) and type the followings.
> cd %SystemRoot%\System32
:: Take Owner & Permissions
:: Here set the HKEY path (after the equal sign _HKEY=here\place\the\path )
> set "_HKEY=HKEY_CLASSES_ROOT\AppID\{3eb3c877-1f16-487c-9050-104dbcd66683}"
:: Take Owner
> SetACL.exe -on %_HKEY% -ot reg -actn setowner -ownr "n:Administrators" -rec Yes
: Processing ACL of: <classes_root\AppID\{3eb3c877-1f16-487c-9050-104dbcd66683}>
SetACL finished successfully.
:: Take Permissions
> SetACL.exe -on %_HKEY% -ot reg -actn ace -ace "n:Administrators;p:full" -rec Yes
: Processing ACL of: <classes_root\AppID\{3eb3c877-1f16-487c-9050-104dbcd66683}>
SetACL finished successfully.
Done! Now you can edit/rename or delete the KEY.
--------------------------------------------------------------------------------------
How to get Registry Admin Owner & Permissions using a Batch.cmd:
[3] Make everything in one batch.cmd automatically
This batch should work on every Windows version from 7 and over. (because is Command Prompt!)
The following batch will make everything automatically:
* Check for all "WebCache" AppIDs if they are exist in the registry,
* Get Reg Keys Admin Owner & Permissions,
* Backup All AppID reg KEYs into a folder,
* and then Delete all of them from registry.
All files backups will be created, so you can revert any time back to previous states,
by double clicking any of the .reg files created, in the
[BACKUPS]_WebCache folder.
Just Follow the steps:
Download the "
SetACL.exe", copy it where the Command Prompt or Batch file.cmd starts from.
1. Download, (extrat it if it's in .zip) and place it on Desktop.
Then Copy it to "C:\Users\%UserName%\AppData\Local\Microsoft\Windows\WebCache" folder. (by cmd or manually)
(eg.:
copy "%UserProfile%\Desktop\SetACL.exe" "C:\Users\%UserName%\AppData\Local\Microsoft\Windows\WebCache\SetACL.exe")
2. Make the Batch.cmd file.
a. Copy-Paste the following CODE into a New text.txt file and save it,
b. Rename it as Backup_Everything_and_Delete_AppIDs.cmd and,
( if you can't see the .txt file extensions, enable file extensions:
File menu > Tools > Folder Options > View (tab) >
[Uncheck] "Hide extensions for known file types" )
c. Place it in the "C:\Users\%UserName%\AppData\Local\Microsoft\Windows\WebCache" folder.
d. Run it (double click it).

Also, I copied the "WebCache" folder to the "[BACKUPS]_WebCache" folder, and then I deleted all files inside the original "WebCache" folder.
( deleted all files except of the "..\WebCache\[BACKUPS]_WebCache" folder ofcourse.)
With this way, everything is backed up (just in case), the "AppID" is disabled, and the PC is clean.
