Announcement: Windows Update Causes Display to Be Blacked Out
MicroSoft has issued an Update for Windows, that is causing problems with Displays. The following is from Talbot McInnis, who tracked down this problem, and offers a fix:
"MS bulliten MS13-057. Specifically, on XP kb2834904 and on windows 7 kb2803821 is causing a problem
For us, it occurs when decoding WMV9 files. Not all uses of WMV decoding are affected, but I confirmed that when connecting the WMV decode DLL to a sample grabber for RGB32 video, the frames arrive black on top, so that points directly to decoding internals of the WMV Decode dll.
You can uninstall these windows updates to resolve your problem."
There are several threads on the problem that this Update is causing on the PrE and PrPro Forums, so one can get more details. So far, there is not another fix from either MS, or Adobe.

Also, recommended in many of the threads already posted on this matter
a. For now, set Windows Updates to require your permission for downloading and installing of the Windows Updates
b. If you do catch the offending kb in Important Updates before it has a chance to install, right click it and select Hide.
Please let us know if you are OK with the details.
Thank you. Will get rid of update.
