How to install Windows 11 on an unsupported PC

Windows 11 has been available for download recently, but not everyone can install it… at least officially. This is due to specific Microsoft requirements, such as a certain minimum processor and a TPM 2.0 chip. But it is possible to circumvent the requirements and even Microsoft explains how to do it.

Install Windows 11 on an unsupported PC

On its site, Microsoft has a page that explains the different methods to install Windows 11, including that for people who have an officially unsupported PC. The method is as follows:

  • Open the start menu
  • Enter regedit.exe and validate to open the registry editor
  • At tree level, go to HKEY_LOCAL_MACHINE SYSTEM Setup MoSetup
  • Right click on MoSetup and select New> 32 bit DWORD Value
  • Give it the name AllowUpgradesWithUnsupportedTPMOrCPU
  • Double click on the value that has just been created, put 1 and validate by clicking on OK
  • Restart your pc

With this manipulation (which has to be done only once), your unsupported PC will authorize the installation of Windows 11 because it will not take into account the model of the processor or the TPM 2.0 chip.

Should we take the plunge?

Is it a good idea to do an installation? Microsoft says it does not recommend this operation, although it does explain how to work around the system. But for now, everything is working normally. So if you want Windows 11 at all costs and if you have some computer skills. These could be useful in case of possible problem to find a normal use.

Otherwise, you can stay on Windows 10. Microsoft has already said it supports this operating system until October 14, 2025. There will be security updates for another four years. On the other hand, do not expect big news. Microsoft will naturally bet on Windows 11, now that the new operating system is available to everyone in its final version.
