I would love to see stats specifically for those pcs.
I'd love to see MS leave W10 taskbar, etc. functionality alone...or improve on it (without advertising). It is immaterial if it looks like a dock or a bar. SD can fix that with Start11/24H2 or whatever nomenclature pleases. The functionality matters the most to me, but appearance is almost as important.
TPM 2.0 can exist independent of W11. It was a requirement for W10 in 2016. MS seems to make the claim that TPM 2.0 is the be all and end all of security. That's nonsense. OS security can be obtained without a new OS, or a special chip. Many older machines can have it enabled via the BIOS.
0Patch proves that W7 can be run securely in the current worm/virus rich environment. Jafo has remained on W7 safely to this day, and happily uninfected.
