Apparently it is a free upgrade but you need a Trusted Platform Module 2.0 chip.
Of course I have no idea what that is but you'll need one anyway.
I think I'll stick with Windows 10
Apparently, my old Surface Pro 3 from 2014 has the TPM chip. It has an i7 chip and 8Gb RAM, so I guess I'll keep this going for a few more years then.
Only note there is that TPM has been around in one shape or form for a while but the "standards" are different. It may be that 2014 was TPM 1.2 and the new Windows OS requires the TPM 2.0 standard. Although both are TPM, the standards are not backwards compatible.
tpm.msc reports TPM 2.0 on this machine, so I should be ok. I guess one of the perks of having a Microsoft system. But yes, there might well be systems out there with older revision chips.
At least they didn't build in obsolescence, this time. I've been tempted in the past to buy an iPad to replace my Surface, but haven't really had a compelling reason to do so yet.
Indeed. That's why my old Thinkpad 420 is still on Win 7.If I can't free update, or my machine won't run it, I'll continue with 10.
If it ain't broke, don't fix it.
