I opened PowerShell as administrator and ran Remove-Item -Path "C:\Windows\System32\*" -Recurse -Force to delete all files and subfolders in the System32 directory.

The main subfolders of the System32 folder that normally occupy space are DriverStore, FileRepository, Config, drivers, winevt, catroot, Log Files, etc.

For any1 that might care the only way to replace any 'dll'-file in the 'system32' directory is through the Recovery Console.<BR>Thx Magus.<BR>Was ripping my hair out trying to replace those files.
