WMI filter causing slow boot up

Hi there,

We currently store Windows XP and Windows 7 desktops in one single OU and we have multiple GPOs setup specifically for Windows 7 and those GPOs are applied to Windows 7 machines only using WMI filters. Please find the Syntax below for the WMI query for Windows7:

Namespace: root\CIMv2
Query: select * from Win32_OperatingSystem where Version like "6.1%"

The issue we are experiencing is discussed here:
http://support.microsoft.com/kb/974524

Please let me know how can we modify the query to fix this issue.

Thanks,
V
