I don't remember them being so bad. Windows 7, 8 were great. Visual Studio 6 was good. Excel was top quality for a long time. What used to be annoying to me was that Microsoft ignored the common Unix conventions for no good reason and tended to reinvent stuff. It was like smart nerds were tasked to come up with stuff without any awareness of prior art, or as if Bill G snd Steve B were trying to lock in customers into incompatible stuff. Obviously not great but working. What we get now is pure slop and negligence.
