It actually is worse than "that bad". Windows 2000 wasn't "that bad" - everything after that has gone downhill.

Objective reasons why Windows is extremely shitty:

1. with every new Windows version, the same settings are shuffled around and users have to re-learn the interfaces to find stuff they had been able to easily find before
2. bloatware
3. tons of software is shoved down your throat with opt-out options either not available, or you have to jump through literal hoops to get there
