The solutions was to go into Device Manager, System Devices, and remove all devices that started with the name “Surface”, i.e.

The Home Button and Volume buttons didn’t work properly for me after the upgrade.

The same process will work on the Surface Pro 4 / SP4 and Surface Pro 5 / SP5, as their processors are also officially unsupported.

So far all features/functions of the SP3 have worked for me under Windows 11.

The SP3 is a great platform for testing out new Windows 11 features.

The Android Amazon Appstore could be a useful reason to upgrade.

Windows 11 doesn’t have any huge features that make it a extremely compelling upgrade.

My SP3 is now a lab/test machine for me, so if it ends up in an unsupported state, that is fine. “ Devices that do not meet these system requirements will no longer be guaranteed to receive updates, including but not limited to security updates.” Right now unsupported CPUs are receiving updates.

Unsupported CPUs may not receive future updates Windows updates from Microsoft.

Make sure to click the button Accept during the start of the install process that I acknowledge this computer isn’t supported, might be damaged, etc.

Download and run the Windows Installation Assistant. reg file to install the new registry value. “AllowUpgradesWithUnsupportedTPMOrCPU”=dword:00000001 To allow an unsupported upgrade, add a single registry value.

The SP3 / 4 / 5 meets all other requirements, TPM 2.0, Secure Boot UEFI, etc. Officially, the processor of the Microsoft Surface Pro 3 (SP3 / SP4 / SP5), is not supported by Windows 11. Yes, you can upgrade a Surface Pro 3, Surface Pro 4, or Surface Pro 5 to Windows 11. The “Registry Add Method” is still the easiest/quickest for an in place upgrade. An SP3 install doesn’t require a Windows 11 Key as it gets one from the system/hardware.

Update : Confirmed the “Rufus” method works for a clean install on the SP3.

If this method doesn’t work for you, scroll down for info on the “Rufus” method, “AveYo’s MediaCreationTool.Bat” method, and “editing Windows 10 bootable USB” method. Update : The “Registry Add Method” instructions in this article are confirmed by Robert L and MOEJJ to be still working fine.
