If you forgot your VM’s logon ID/PW, you have a few options to get back in there. Note: Domain Controllers don’t have local users so these tricks won’t work with them….
- If this is a brand-new VM (never logged on or configured), it’s generally fastest to delete and recreate it.
- If the VM extension installed, you can reset the password via powershell.
