I’m running Windows Server 2008 on my notebook and was wondering about a slow boot time showing applying computer settings which took more 3:06 minutes. Now I have found the solution and my system start takes only 1:50 minutes which is an enhancement of more than one third. So here is the detailed description of what I have done…
Error description
When you take a look at the event viewer you will see the following warnings:
- EventID: 6005
The winlogon notification subscriber <GPClient> is taking long time to handle the notification event (CreateSession). - EventID: 6006
The winlogon notification subscriber <GPClient> took 134 second(s) to handle the notification event (CreateSession).
Solution
My notebook smart card reader which caused trouble with the Group Policy Client. After disabling the smart card reader in device manager my system boot was faster.

Although 1:50 minutes isn’t as fast as my Vista partition it saves time…
