We have several GPOs containing many settings that have accumluated over time. I have spot-checked some of them and stumbled over settings that only apply to Windows XP (we exclusively run Vista and Win7 clients). As we are having serious performance issues caused by overloaded GPOs I need to get rid of this settings.
How can I filter/show all settings within a GPO that only applies to Windows XP?
I am aware of the GPMC filtering function, however it does not fulfill my requirement.
To my knowledge this isn't possible - the "Applies to" description is merely a string embedded in the adm(x) file. There's no "IF" processing for this - regardless of what version of Windows processes the Group Policy it'll set that setting, whether it has any impact or not.
Group Policy is exceptionally quick at processing individual registry based settings and I highly doubt this is the root of your problem, though.
