Install Windows 7 on HP 800 G3/G4/G5 (Coffee/Kaby Lake CPU, byI7-9700)

Within last five yrs, I have been testing OS Windows 7 10 11 over 50 computers
(mainly HP, while including ASUS Dell ECS Lenovo MSI).

1. W7 is most compact. and runs fastest.
2. W10 is most stable. but runs slower than W7. kind of wasting CPU power.
3. W11 is my last choice. sluggish.

hence, go Windows 7 when I can. If instability is the main concern, W10 could be a better choice.
