I triple-boot Windows 7 Ultimate, Windows 10 Enterprise 1809 (Cancer UWP filth included), Windows 10 Enterprise 2019 LTSC.
I use the Cancer Edition to play Gears of War 4, and as a crash test dummy (all updates enabled and antivirus software installed).
This allows me to be extremely critical of the Redmond Retard filth based on experience rather than conceptually.
95% of the time I use Windows 7 unless I am running benchmarks that require Windows 10/DX12, (such as Time Spy and Night Raid) then I boot into LTSC for that. Windows 7 beats Windows 10 in just about every non-DX12 benchmark that exists except for Fire Strike.
Cinebench, wPrime, 3DMark Vantage, 3DMark 11, Sky Diver, Cloud Gate, Ice Storm, AIDA64 Memory Benchmark... you name it... Windows 7 wins them all and usually by a substantial margin.
