I use the language packs. Just did updates kb2656372,2656355,2633879,982670, microsoft silverlight, 972813,972813,2675157,2618451, and 2532531. System completely froze up to the point of booting in safe mode and removing avast. I had downloaded the fix, extracted it per instruction. The patch did not work. So it looks like the main issue has to do with one of these updates.
