How to install Windows 11 on an incompatible computer

Microsoft has tightened the requirements for computers on which Windows 11 can be installed, so not all PCs can be updated. However, enthusiasts with XDA Developers have already found a way around the restrictions to put Windows 11 even on older and unsupported machines.

Windows 11 requires a computer to have at least 4 GB of RAM, a TPM 2.0 physical encryption module, and Secure Boot support. The presence of all this is checked at the initial stage of the installation, but you can enter the data into the registry so that such a check is not carried out. Here’s how to do it:

Start the Windows 11 installation using an ISO image or bootable media. When during the installation a message appears about the incompatibility of the computer due to non-compliance with the minimum requirements, call the command line with the Shift + F10 key combination, enter the regedit command in it and press Enter.


The Registry Editor will open. Go to the HKEY_LOCAL_MACHINE SYSTEM Setup branch, right-click on it and create a LabConfig section in it. In this section, right-click on an empty space and create 32-bit DWORD parameters BypassTPMCheck, BypassRAMCheck, and BypassSecureBootCheck. Give each one a value of 1.

Close the Registry Editor and Command Prompt, then click the return button on the incompatibility window and start the installation process over. There will be no verification of the amount of RAM and the presence of TPM 2.0 and Secure Boot; instead, the Windows 11 installation process should begin. When it is completed, the computer will reboot several times.

Keep in mind that Windows 11 can be unstable on incompatible computers with errors and abnormal restarts. Windows 11 will be officially released this fall, and test builds are now available as part of the Windows Insider Experimental Program.
