This is driving me nuts a bit, this folder, WindowsApps takes up ~3.5 gigs in Program Files, and there seems to be no way to remove it (at least parts of it). I've tried uninstalling apps, uninstalling apps via PowerShell, uninstalling apps with CCleaner. The apps disappear from the start menu, however this folder stays the same. Some apps even have more copies of itself (pre-update versions I guess).

Traditional 'hard delete' doesn't work either (folder is read-only), when I try to change the attribute it gives an 'access denied' error, even though my account is a full control admin. account with UAC turned off etc.
Is there a way to delete those apps somehow?
Thanks, cheers!
