Windows 11 is due out soon, so I thought I'd check out if my PC and laptop can run it. Apparently not it seems. I would never consider updating Win10 to 11, but would want a new install of WinPro-11 or whatever they will call it. From experience updating any operating system from Microsoft always has the effect of removing the will to live from anyone who attempts it!
So I ran the TPM test

* and both machines failed. The PC is around 4 years old and the laptop a little younger. On the PC I can retain the processor and replace the motherboard etc and add more memory, but the laptop is not so easy. The PC has an Intel Core i5 3.2GHz x64 with 16GB of Ram, a huge drive and Win10Pro. The laptop, is a slower AMD x64, 16GB Ram but with the somewhat less private and secure Windows10 Home. Windows10 is supported until 2025 and should be OK for a few years beyond that, so no Windows 11 for me it does appear.
The story around the campfire is that Windows will switch to a monthly subscription in the near future. Maybe not with Win11 but it is on the agenda as the preferred method of maintaining growth in OS sales.
Personally I have no intention of becoming a subscriber to Microsoft. So now I have decided that I have little choice but to make the switch to Linux sooner, rather than later.

" for Trusted Platform Module: in the Run box type TPM.msc and run and check. There is also WindowsPCHealthCheckSetup.msi from Microsoft you can install and run )
