Microsoft will announce its next-gen operating system for desktop, Windows 11, on June 24 event. However, the preview build of Windows 11 has leaked online, and it unveils what will be Microsoft’s new OS. Windows 11 looks like the proposed Windows 10X with a minimalistic design, new taskbar, simplified start menu, new action center, new file explorer, and more.

The leaked Windows 11 ISO file is available for download, and the installation process is as same as Windows 10. But, if you are trying to install Windows 11 on your old computer, you may get the error “This PC can’t run Windows 11“and “This PC must support TPM 2.0” and “This PC must support Secure Boot” messages. There is a workaround to fix these issues on your PC.

Fix the error This PC Can't run Windows 11

This Windows 11 build requires TPM 2.0 and Secure Boot on your system BIOS/UEFI for proper installation. Without the Trusted Platform Module (TPM 2.0) and Secure Boot, you will not be able to install the build, so you will get a “this PC can’t run Windows 11” error message. This workaround will help anyone to install the new Windows 11 OS on any compatible system. It means you can install Windows 11 without the TPM 2.0 and Secure Boot enabled on your PC.

Steps to Fix the PC can’t run Windows 11

1. First, you need to download Windows 10 ISO file (preferably the May 2021 build) from Microsoft website (link) with the help of the Media Creation Tool.

2. After downloading the Windows 10 ISO image file, right-click it and select the Mount option and mount the file as a drive.

3. Next, open the new drive, and inside it, open the Sources folder.

4. Inside the Source folder, select and copy all the files (except install. wim file).

  1. you need to copy only the – appraiserres.dll – file from the windows 10 installation resources folder, not all the files…..

  2. I tried all the solutions I could find also the ones mentioned here and could not get it to work. I then got it running in a vm. I then made an acronis backup by booting from cd in the virtual machine. I then transferred the backup to a flashdrive and restored it to my physical pc afterwards
