Upgrading older PC's to Windows 11
Published 6 October 2021
Microsoft has softened its stance on hardware requirements for Windows 11 by documenting a way to bypass them....
The bypass is easy: one registry setting called "AllowUpgradesWithUnsupportedTPMOrCPU". Once set, users can run the Media Creation Tool to create an ISO. It is then possible to mount the ISO with a right-click on the same PC and run setup from there to upgrade while keeping installed applications and documents.
There are limitations, one of which is that TPM 1.2 is still needed, revealing that Windows 11 has hard as well as soft requirements.
