You still don't get it. Windows is badly designed. It doesn't work well. It doesn't work nearly as well as it could, or as well as other systems. Ths is frustrating for two reasons:
1. Stupid people make MS so big in market share that the rest of us have no choice but to use it. There is no such thing as true cross-platform compatability, so we're stuck with it, even though we know better - evidence your thinking that reinstall and repair are the same things, have to be and should be. Ridiculous.
2. The resources the behemoth uses on spying on us, evidence WGA, could be put to better use, making their software work better.
