Filter by installdate

I was once asked if you could apply a GPO to computers before a certain date. My first answer was the simple solution, create a group add all computers that exist at that time into the group and then filter on that group.

If possible always do it the simple way, but they asked what would happen if a computer was reinstalled. Since the computer account will be reused it will still be in the group, this was a problem. So at this time we have to decide where to complicate things.

Do we want to complicate the tasksequence and let it remove the computer from the group or do we want to use a WMI filter on the GPO.

WMI filter has limitation they require a working WMI on the client, they also require that the client is running Windows XP or Windows 2003 Server (who has that running anyway right?). Using WMI we can create a simple WMI filter that will allow us to only target computers that are installed or reinstalled after a certain date.

wmifilter - only olders installs

It is a simple as that.
