On startup, the computer hangs on either “Please wait” or (if verbose messages are enabled) “Applying Microsoft Offline Files Policy”.
This issue may be present even without any Offline Files GPO’s being set.
This behaviour has little to do with Offline Files, but is actually caused by running PowerShell scripts on startup.
Remove any startup scripts being applied to the computer in Group Policy and ensure startup time has returned to normal.
If this is the case, add them back one-at-a-time, rebooting after each to find the culprit.
