My test ROS

In General I have tested the system as the user. Opened Opera browser 12. Downloaded and installed WinDjView. Opened, played with him, was closed. Opened Solitaire. The system is hung. I was thinking to close the Virtual Machine, as neither mouse nor keyboard not worked, but at some point, ROS came to life. I shut down solitaire and minimize the browser, but it turned out that Desk just disappeared. The start menu didn't work. And everything looked frozen, but mouse and keyboard were alive and I was able to run taskmgr. I tried to complete the process Explorer.exe after that, the system completely hangs.
