Windows 10: I really messed up, Set permissions for HKEY_CURRENT_USER and HKEY_CLASSES_ROOT with all...

As the title says I messed up super badly, I needed permissions to delete some registry keys and I thought the best way to make sure I wouldnt have to keep setting permissions for each key I opened permissions for HKEY_CURRENT_USER and HKEY_CLASSES_ROOT and enabled "replace all child object permission entries with inheritable permission entries from this object"

So good news is I can now edit whatever registry keys I would like to, bad news is I cant even run cmd anymore because "No such interface supported"

Any and all help would be appreciated

Windows 7 - Messed up permissions

Forget it and get Windows 8! *Smile

Messing with permissions is really for advanced users, you can't win the Kernel with a crowbar *Smile

 

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

 

Permission issue

Presumably because TrustedInstaller is the owner (hence you need its permission), suggesting that img3.jpg was installed by Windows at some time.

Presumably that also means it can be uninstalled. How did you get it in the first place? Where is it located?

If you really want to delete it yourself, then taking ownership would seem a logical first step.
