Aero Lag when closing?

[Mr PC Fixit]

I have windows 7 ultimate.Here are all my installed updates + SP1 I don't have a virtual machine installed on my computer.

yetyhunter..... just had a look at all your updates.
I see you have Crysis Patches installed. Lets start with the obvious first.

According to Gamefront , the crysis patch "Corrected a number of memory leaks with FSAA modes. *Optimized Object Motion Blur for DX10 Very High Spec".

Try uninstalling both patches, reboot and see how you go.

I don't think it has anything to do with crysis patches because this bug was present on 5 different computers i have installed windows,the bug is there at the first start up.

This might seem like a stupid question.... but do you have the right drivers installed ? nVidia or Radeon ? Using Windows 7 Drivers or the card manufacturers actual drivers ?
