On: A tale of two path separators

And you need `cd /d` to switch drives. This was how I rendered a Windows computer non-bootable for the first time. Ran Command Prompt as admin (because I was logged in as a user that didn’t have write access to D:\backups), and it starts in a rather important directory, then:

  C:\WINDOWS\system32>cd D:\backups\some-huge-directory
  C:\WINDOWS\system32>del /s *

Oops. I learned to look twice before running a big dangerous command. And to use /d.

Or you could use powershell and avoid the issue ;).

Though nowadays system files should be protected even from admin and even if you do manage to delete them, Windows can restore them.

PowerShell didn’t quite exist back then!

Oof, cd silently staying on the wrong drive and then del /s is the worst possible version of this. /d the hard way.
