How is that insane? RRP Physical or Digital retail copies of Pro are at least £200, and key resellers typically charge £10-20 per license for non retail - hardware locked licenses. So even buying a new motherboard every single year for 10years and needing a new license would only cost around the same price for licenses.
And 10years is a completely disingenuous claim when all hardware from prior to 2019 (5 years) has all been made obsolete to Windows 11, despite UEI secure boot and TPM 2.0 being just as vulnerable as before. Meaning that unless you built a machine in 2019 with a £200 retail version of Windows 10 Pro you've got no valid way to enjoy that 'insane' value.
It is just Microsoft trojan horsing Windows to help make non-obsolete PC hardware look obsolete and help their OEMs sell new hardware and in return let them get their cut of new OEM Windows license sales on said hardware. If they weren't so big and powerful, this type of zero solution to facilitate legally upgrading to Windows 11 on older hardware, and provide a dongle solution to the TPM issue would probably get them in trouble with regulators, as the compatibility bar for Windows 11 is totally self serving, and this support offer just exposes a further shakedown.
