Run logon scripts synchronously
Directs the system to wait for logon scripts to finish running before it starts the Windows
Explorer interface program and creates the desktop.
If you enable this policy, Windows Explorer does not start until the logon scripts have
finished running. This setting assures that logon script processing is complete before the
user starts working, but it can delay the appearance of the desktop.
If you disable this policy or do not configure it, the logon scripts and Windows Explorer are
not synchronized and can run simultaneously.
