27. Fix Undeletable System Volumes
System Volume information can be accidently copied to other volumes (e.g. USB drives) using robocopy and copying the entire drive. This will lead to directories that cannot be deleted even if they are not needed.
Take ownership and grant full privileges for everyone to remove the directory.
takeown /f ".\System Volume Information" /a /r /d y
icacls ".\System Volume Information" /t /c /grant administrators:F System:F everyone:F
rd ".\System Volume Information"
