Install Windows 11 On Old PC With No TPM 2.0

Here's how to install the official Windows 11 operating software on an old PC with no Trusted Platform Module (TPM) 2.0 that's required by Microsoft.

Our desktop computer has a third generation Intel Core i5 processor, DDR3 RAM kit and a Foxconn motherboard with no TPM, but we installed the leaked Windows 11 build 21996.1 and upgraded it to the official Windows 11 build 22000.51 successfully.


  1. Download both the Windows 10 ISO and Windows 11 leaked ISO.
  2. Using Rufus, make a Windows 11 bootable USB.
  3. Mount the Windows 10 ISO and copy the content of the Sources folder except "install.wim" and paste the copied files to the Sources folder of the Windows 11 bootable USB. This will bypass the TPM 2.0 requirement.
  4. Install the Windows 11 build 21996.1 in your computer.


  1. After installing Windows 11 using the leaked ISO, go to Settings then 'Update and security' and click on 'Windows Insider Program' to enroll.
  2. Choose the Dev channel and restart your computer.
  3. After rebooting, go back to Settings, 'Update and security' and then 'Windows Update'. The 'Windows 11 Insider Preview 10.0.22000.51 (co_release)' should be available for download.

After the installation process, Windows 11 will be upgraded to build 22000.51 with added features.

That's it. Here are screenshots of our installation:
