If you’ve decided you want to upgrade from Windows 10, here’s how you can get the free upgrade—even if Windows Update doesn’t offer it. This works if Windows 11 doesn’t officially support your PC, too.
How to Check if Windows 11 Supports Your PC
To check if Windows 11 officially supports your PC hardware, download and run Microsoft‘s PC Health Check app.

Click the “Check Now” button and the tool will tell you whether Windows 11 officially supports your PC. If it doesn’t, the tool will give you information about why. If the problem is lack of TPM 2.0, for example, you may be able to turn TPM 2.0 on in your PC’s UEFI firmware (BIOS.)
