Hello forum, I'm trying to install Win8.1. After a clean install I go to update windows. But when it begins to update the KB2919355, my laptop just freezes, showing Disk usage 100% for 30 minutes. I have tried reinstall windows, installing the downloaded package, using microsoft autoupdate fixit. Still, it just gets stuck there, once I let it hang there then after 40 minutes it says error. Any clue?
