Windows 10: Registry subfolders empty in HKEY_CURRENT_USER

I was about to look through my registry to clean some old things up, but before I could I noticed that under HKEY_CURRENT_USER all the subfolders had weird titles as if using an incompatible font, and each contain an empty default registry. This is probably over a thousand folders long, starting from what you see in the screenshot all the way to Z in odd combinations. The standard registry folders, such as System and Software are still in there apparently, but only seemed to reappear after a restart. What caused this, and is there a way to clean this up? So far this hasn't seemed to have caused any other problems.

Thank you for any help.

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

 

Registry folder removed after reboot

You need to do this to find out:

1. Play the game, then close it.
2. Check if the registry subkeys of HKEY_CURRENT_USER\Software\JavaSoft\ exist.
3. Reboot.
4. Check if the registry subkeys of HKEY_CURRENT_USER\Software\JavaSoft\ exist.

I strongly suspect that the answer is "Yes" in Steps 2 and 4. This would mean that the game deletes the subkeys.

 

Recent File List

Remove-ItemProperty -Path "Registry::HKEY_CURRENT_USER\SOFTWARE\Microsoft\Windows\CurrentVersion
\Applets\Paint\Recent File List" -name file1

Remove-ItemProperty -Path "Registry::HKEY_CURRENT_USER\SOFTWARE\Microsoft\Windows\CurrentVersion
\Applets\Paint\Recent File List" -name file2
Remove-ItemProperty -Path "Registry::HKEY_CURRENT_USER\SOFTWARE\Microsoft\Windows\CurrentVersion
\Applets\Paint\Recent File List" -name file3
Remove-ItemProperty -Path "Registry::HKEY_CURRENT_USER\SOFTWARE\Microsoft\Windows\CurrentVersion
\Applets\Paint\Recent File List" -name file4
Remove-ItemProperty -Path "Registry::HKEY_CURRENT_USER\SOFTWARE\Microsoft\Windows\CurrentVersion
\Applets\Paint\Recent File List" -name file5
Remove-ItemProperty -Path "Registry::HKEY_CURRENT_USER\SOFTWARE\Microsoft\Windows\CurrentVersion
\Applets\Paint\Recent File List" -name file6
Remove-ItemProperty -Path "Registry::HKEY_CURRENT_USER\SOFTWARE\Microsoft\Windows\CurrentVersion
\Applets\Paint\Recent File List" -name file7
Remove-ItemProperty -Path "Registry::HKEY_CURRENT_USER\SOFTWARE\Microsoft\Windows\CurrentVersion
\Applets\Paint\Recent File List" -name file8
Remove-ItemProperty -Path "Registry::HKEY_CURRENT_USER\SOFTWARE\Microsoft\Windows\CurrentVersion
\Applets\Paint\Recent File List" -name file9
...

you get the idea. ( too lazy to put it in a for loop and test it.

or just open regedit and remove all the fileX from that key.
