Upgrading an unsupported Windows 10 PC to Windows 11
I document my journey upgrading my unsupported Windows 10 PC to Windows 11, including the mistakes I made along the way.
It took me a while (several hours, to be exact) to successfully upgrade my unsupported Windows 10 PC to the latest version, Windows 11. In this article, I hope to share my experiences and any lessons learned to help others avoid similar pitfalls.
My PC wasn’t eligible for the Windows 11 upgrade due to an unsupported CPU. Therefore, this article may not be relevant for any other incompatibility reasons.

Bypassing Windows 11 Requirements with the Registry
There is an official way to bypass the Windows 11 requirements by adding a value to the registry. Here’s how to do it:
- Open the registry by searching for it in the Windows menu or by pressing
- Navigate to
Computer\HKEY_LOCAL_MACHINE\SYSTEM\Setup\MoSetup. If the
MoSetupdirectory doesn’t exist, right click on
Setup > New > Keyand name it
- If it doesn’t exist already, create a new DWORD record (right click,
New > DWORD (32 bit) value) and name it
AllowUpgradesWithUnsupportedTPMOrCPU. Set its value to
1(hexadecimal, by default).
- Restart your PC to apply the changes.

Before downloading the ISO, it’s important to determine your Default system UI language. This is different from your current system UI language and cannot be changed. I learned this the hard way, wasting two hours of my life…
To find your Default system UI language:
- Launch the command prompt (
cmd) as an administrator by searching for it in the Windows task bar, right clicking on the program, and selecting
Open as administrator.
- Run the following command:
dism /online /get-intland note the
Default system UI language.
