when i try to launch windows, the following message appears "please do not power off..."

Hello everyone , everything was great with parallel desktop of "Windows 7" ( running on a MacBook Pro ),until when a automatic update of windows 7 have been downloaded before I "power off" my parallel machine ,so I let all the night my Mac (in charge of course ) and let it download and install the updates before he "turned off" , but when I woke up (10 hours later ) Windows was still installing those updates !
So I close parallel desktop and restart it to see what happened ,but nothing have changed , the same windows with the same message and same updates ,every time I restart parallel desktop nothing happened ... and there's always this message (screenshot ) and I can't access to Windows.
What can I do ?
Someone can help me ?
Thank you
