Windows 11 has स्वेद steadily gotten worse. It was better at launch! For me, the phone link feature seems to constantly consume 8-10% CPU regardless of whether my phone is connected or not. Windows malware process is another big offender, making me wonder if an actual virus might have lesser effect on performance. The start menu sometimes hangs if I try to type something in the search box. It just screams incompetent software to me.

I'd love the same test but with various Mac versions, and with Intel and Arm machines

Windows 11 shouldn't have even run on that 2nd gen Intel processor. Was it forced into booting?

TLDR Windows 11 comes last in almost all tests.
