One needs to remember a lot of processors were not supported by Windows 10 originally, the only difference this time is Microsoft have put a couple more obstacles in the way, which look like they will be solvable either by MS backing down or by some of the large number of ingenious geeks out there. ;o)
I've now got my AMD rig replaced the Ryzen 5 1600 with a Ryzen 7 3800X (8 cores 16 threads) replaced the 16GB of 2133MHz ram with 16GB of Corsair Vengeance LPX @ 3000Mhz and it is now flying and passes the Win11 tests.
The Intel rig does have TPM2 had to enable Intel Virtulisation before it appeared in the bios, was a guess as there is zero info on TPM in the manual and a blank space on the motherboard labled TPM but no header anyway enabled it and it's TPM2. Processor currently as it's a 6700K fails, if MS allow 7th generation processors the Z180P will take a gen 7 CPU but no rush on that.
A bit loathe to mess up my upgraded system just yet but I need something to play with Win11 on! Thought of getting a cheap laptop or a refurbished one but I'm not fond of laptops, so got a small Dell Inspiron 3881, i5 10400 6 cores, 256 GB M2 and a 1TB 7200 RPM HDD from Dell Outlet, have to wait a couple of weeks for it though, not intending to run Trainz on it! although I could stick either my GTX1060 or 970 in it as they are small enough to fit. Got a spare slot in my Custom desk setup that it will fit in vacated by an ancient Athlon Linux box with a dead motherboard, Gigabyte and leaking capacitors anyone?
Dell UK had got loads of refurbished stuff a few days ago and it was mostly 10th generation but it's going fast!
