allowupgradeswithunsupportedtpmorcpu: What is it? How to Use & Easier Alternatives

Windows 11’s recent release has brought along its fair share of controversies and debates. One of the main ones being around its inherent hardware and software requirements. This essentially means that though the OS at the base is compatible with 1GHz dual-core processors, the requirement for TPM, Secure Boot, and UEFI essentially means that you can’t use components released a few years ago.

A registry value called ‘AllowUpgradesWithUnsupportedTPMorCPU’ has come to light recently as it was endorsed by Microsoft itself, allowing user to circumvent the Windows 11 requirements. Let’s find out more about this registry value.

What is the AllowUpgradesWithUnsupportedTPMorCPU?

‘AllowUpgradesWithUnsupportedTPMorCPU’ is a new registry value created by your Windows 11 setup at the time of upgrade. If you found this value by chance then you were likely trying to update your system while booted into Windows. Editing this value manually can help you bypass compatibility checks during the upgrade process which can help you install Windows 11 on unsupported PCs.

However, you can create this entry manually in the speficied location in the registry (see below) and set its value to 1 to let system ignore the requirements for Windows 11. This way, you are able to install Windows 11 on unsupported hardware.

What happens when you use AllowUpgradesWithUnsupportedTPMorCPU?

Manually editing the ‘AllowUpgradesWithUnsupportedTPMorCPU’ value bypasses compatibility checks performed during the Windows 11 setup. Enabling the value allows the setup to upgrade your system even if you do not have TPM or Secure Boot.

This registry value is a background toggle for ‘Install Anyway’ that shows up on systems that fulfill basic compatibility but are missing either of the enhanced security features like TPM or Secure Boot.

Is it safe to use AllowUpgradesWithUnsupportedTPMorCPU?

For now, enabling, disabling, or deleting this registry value doesn’t seem to have any adverse effect on systems. After all, Microsoft themselves shared this little registry bypass so that people looking to try Windows 11 on their otherwise unsupported systems can do so.

The value seems to be created at the time of your setup and should be automatically deleted once you have upgraded to Windows 11. However, you can create it manually to force install Windows 11 on a unsupported PC.

You can manually delete the value as well after installing Windows 11. No bugs, crashes, BSODs have been reported yet when editing the ‘AllowUpgradesWithUnsupportedTPMorCPU’ registry value.

  1. Hi,

    I thought I would mention that it looks like the word “windo” is spelled incorrectly on your website. I’ve seen some tools to help with problems like this such as SpellAlert.com or WebsiteChecker.com. I just thought you should know!
