Delete old windows / program files from second drive?

The absurd “answers” on the microsoft community of course offer things like “Use Disk Cleanup” (which is a blatantly uneducated answer) or “just reformat the drive” (formatting avoids the problem rather than addressing it).

What are the correct steps to delete these old files?

TL;DR: Use a bat file (as Administrator) like:

set FOO=e:\windows
takeown /F "%FOO%" /A /R /D Y
icacls "%FOO%" /T /grant administrators:F
rd /s /q "%FOO%"

Or, for Windows folder, just rename it to Windows.old and use the Disk Cleanup utility (as Administrator)
