Activates Windows against kms8.msguides.com before Windows Update runs
so WU sees correct license state. Uses cscript //NoLogo to route slmgr
output to stdout (dialogs hang in WinRM sessions). Best-effort: activation
failure emits a warning but does not abort Setup — CI builds function
within the grace period.

Placed between Step 3 (WinRM/network confirmed) and Step 4 (user creation).
