Systems Management

Hi. I need to quickly check that newly applied maintenance windows are being picked up by our Win7 PC's. I know there is a report (223) where I can check an individual client but this isn't too handy for checking all the clients in a particular collection. Can I modify this report to show a report on the clients in a particular Collection?

I should also mention that these PC's are exposed to the general public so we are using Deep Freeze. On reboot, this software reverts the Windows state back to the same state it was in prior to a user logging in. As a result the SCCM policys will not be applied unless the client updates during the maintenance period for Deep Freeze. We have a mix just now of PC's with the new policy and some which have no maintenance periods definded.

I just need a way to easily check which PC's in each collection need to be updated manually with the new policy.
