Windows XP is Microsoft's first best operating system, Windows 7 is the second, but also the last. Starting with Windows 8, Microsoft has made Windows worse and worse. And when it came to Windows 11, Windows was already very sick. Four of the most serious problems are:

1. System is becoming more and more bloated, especially with the huge amount of junk apps pre-installed
2. System performance is getting lower and lower, with hundreds of backend processes
3. System is getting harder and harder to use, complicating all the simple operations
4. Privacy protection is getting worse, as Microsoft itself starts collecting all kinds of data from users like crazy
