Windows 10: I Think I messed up Windows permissions.. :/

So I've been having applications acting strangely, where I would have to launch steam as admin to play certain multiplayer games etc.. Now I'm trying to make a game in Unreal Engine 4.27 and it won't let me export it!! I was messing with the settings on some permissions following the advice on how to boost my fps in a certain game. So I guess where can I go to fix this xD? Not sure where I would go in windows 11, and what are the correct permissions to have if possible too : thanks!

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

Windows 7 - Messed up permissions

So, while trying to delete some folders, i ended up messing up permissions for all of my folders.

I cannot use things like MSconfig.exe, it tells me settings cannot be saved. Word gives me errors and is unable to save to the normal.dot template, and when i restart my computer it hangs before the desktop unless i press one of the F-keys (not sure which one as i mash them).
-pressing the F-key here does not give me a menu, it just allows windows to load for some strange reason. While windows is loading, if i do not press the f-key the computer crashes and i cannot even ctr-alt-del to restart.


Is there any way to reset permissions to default?

I am on an administrator account and UAC is off. I know a re-install will fix it all, but it's annoying to have to do that *Frown
