I've tried to be patient. I've tried to give Windows 8.1 a fair shake.
Ever since I installed it earlier this week, I've been drowning in constant BSODs (with no consistent error message) and total system lockups.
I'm so frustrated that I think I am going to do a complete system refresh. I'm quite annoyed that only "Windows Store" apps are kept installed and the actual programs I use on a daily basis will be blown away in the process because that's not what they promised us a year ago, but whatever.
If this system refresh fails me, I'm going back to Windows 7.
