Slow booting Vista/2008

Alastair Grant | Wednesday 24 December 2008

There are a few posts kicking around the net regarding slow booting of Windows Vista or Windows 2008. With the following event 6006 logged:

The winlogon notification subscriber took 120 second(s) to handle the notification event (CreateSession).

The general suggestions are to fiddle with some network tuning settings, which helps some people. But not others.

I'm running 2008 attached to a Samba domain controller. With a couple of other PC's and virtual machines. I have no need for group policy. So I figured I would just turn off that service. This has resulted in a very fast boot time - problem solved. I get a warning about the service not working in the task tray, but I'm sure I'll figure a way to suppress that.

If you try to disable it you'll find yourself with a greyed out properties dialogue, and not a lot you can do. For some reason this has been "restricted". So you have to override it.


  1. Load regedit (as administrator)
  2. Navigate to: HKLM/SYSTEM/CurrentControlSet/Services/gpsvc
  3. Right click the key and go to permissions
  4. Click Advanced
  5. Click Ownership
  6. Set the owner to Administrators (instead of SYSTEM)
  7. Click OK
  8. Give Administrators full control
  9. Click OK
  10. Edit the value "Start" to have a value of "3" (no quotes)
  11. Close regedit and reboot
