Windows 7 guests freeze after being idle for about 20 mins on both Windows 7 64bit and XP hosts. There was also increase in the CPU utilization for those session processes. I also have Linux and Solaris 10 guests that do not exhibit the same behaviour. I tried pause and resume to no avail. I tried both 3.2.12 and 4.0.0 versions of the Windows Guest additions. Had to go back to VB3.2.12",defect,closed,other,VirtualBox 4.0.0,duplicate,,,Windows,Windows
