I'll call it a piece of s*1t
I have a relatively new computer, and every few weeks it seems, the thing updates itself peremptorily, and every time I shudder about what the consenquences will be for the usability of my computer and my applications.
What will it do, this time? I ask myself. After the last update, which was a few weeks ago, it took smooth scrolling away from my Word for Windows 2003 program (which I keep using because of massive investment in VBA applications that would take me hundreds of hours to convert). It used to scroll properly, now it's all jittery and almost unusable in this respect.
It also has a tendency to restart on its own volition "for updating", sometimes while I am in the middle of a session, or have popped to the kitchen or bathroom, and I lose my data.
Every time I back up onto hard drives, it crashes with a BSOD, and now it doesn't just crash right after the backing up, but it *chooses* when to do so - e.g. 4 hours later, so that I am completely unprepared and lose more work.
This is a terrible OS, and, frankly, the attitude behind it feels like an insult.
