Windows 10: Registry key in HKEY_CURRENT_USER\SOFTWARE\Classes\Local...

I asked another question about this yesterday and another user responded, however I didn't get the answer I was looking for. They said that the key was legit, but he didn't know about it being in the "AppModel\PolicyCache" branch, so I wanted to know if it was a fake key or not. I can upload a copy of the key as a .txt or .reg if needed. Just please someone help me find out if this is a problem or not.

Registry strange behavior in HKEY_CURRENT_USER\Software\Microsoft\...

I tried to clear all contents of
HKEY_CURRENT_USER\Software\Microsoft\Windows\CurrentVersion\Explorer\FileExts
then set security permission to logger user name () to be clear from:

• create key
• set value

and let it inherently apply to all keys under it

But it responds with icons flickering / blinking very often
so I undo the security setting.. but while keeping on registry browsing under this key I came across:

1. The jpg filetype key and userchoice key were created
2. On userchoice key the logging user () ACL was created, and
3. It's set to DENY on SET VALUE !

Is it windows 10 behavior or an intruder's been screwing up ?
Please help me.. many thanks in advance

 

Oddly named entries under Computer\HKEY_CURRENT_USER\SOFTWARE\Classes\

Also a discussion here:

Well, does anyone know what this stuff is or relates to?

I find them right after a Clean Install and right after I've assign certain 3rd party programs to certain file types where they'll appear at the very bottom of HKEY_CLASSES_ROOT after the last entry 'Zune'.

It's a Unicode issue and I've been deleting them for years to no ill effects.

I just had this happen yesterday with my Clean Install of Windows 11 22H2 when I associated *.webp files with XnView.





If you scroll up the same *Classes list you'll find the 'webp_auto_file' entry where it shows the shell command it was associated with:





These Class entries are duplicated in these other keys, but when deleted from HKEY_CLASSES_ROOT get deleted everywhere once you close and reopen Regedit.
