I took the 500GB disk from my dead notebook and decided to keep old data within it as an external storage in a USB case.
The drive was bootable as Windows 7 pro x64, but now I want to remove all system folders from it, keeping all backups and private data untouched, but I need special rights for most of the folders/files inside Windows folder: it requests for TrustedInstaller privileges.
I'm using a Windows 7 enterprise 32bit, logged in as a AD domain user that is also on local Administrators group. I tried taking ownership, but it failed.
How can I remove those unused system folders?
Thank you in advance.
