Quickly Install Windows 11 on Unsupported PCs without TPM 2.0 and Secure Boot

How to Bypass Windows 11's System Requirements and Install on Unsupported PCs.

The excitement surrounding the release of Windows 11 has been palpable, and many users are eager to get their hands on the latest iteration of Microsoft’s flagship operating system. However, there’s a catch: the new, stringent minimum system requirements, which mandate the presence of TPM 2.0 and Secure Boot. For many, especially those with older systems, these requirements are a significant hurdle. A considerable portion of Windows enthusiasts find themselves unable to make the jump from Windows 10 to Windows 11, much to their disappointment. The stipulation that even genuine Windows 10 users need specific hardware features to upgrade is particularly vexing. But despair not! We’ve scoured every available resource and have unearthed a method that lets you install Windows 11 without TPM 2.0 and Secure Boot, and without the intricate dance of mixing Windows 10 and 11 ISO files. Read on to discover a streamlined approach to breaking these barriers.

What are the Minimum System Requirements to Install Windows 11?

To install Windows 11, Microsoft has set forth some essential system prerequisites:-

  • A modern processor with at least 1GHz clock speed and at least two cores.
  • 4 GB of RAM or more.
  • 64 GB of storage or more.
  • Firmware that supports Secure Boot.
  • TPM version 2.0.
  • DirectX 12 compatible graphics / WDDM 2.x.
  • A high-definition (720p) display that is greater than 9” diagonally.
  • Internet connection to complete the setup for Windows 11 Home.

However, as mentioned earlier, there are workarounds to these requirements, allowing a broader range of PCs to enjoy the new features of Windows 11.

How to Quickly Install Windows 11 on Unsupported PCs without TPM 2.0 and Secure Boot?

Follow these steps to install Win 11 on unsupported PCs quickly without TPM 2.0 and Secure Boot:-

Step 1: First, download the official Windows 11 ISO by registering for Windows Insider or any other source.

Step 2: Next, download the WinRAR application to extract the contents of the ISO file.

Step 3: Go to the Extract option (Refer to screenshot) by right-clicking on Windows 11 ISO you have downloaded.

Step 4: This will extract the ISO contents to a folder in a few minutes with the same name as the ISO file.

Step 5: Now, double-click on the folder to open it.

Step 6: Open the sources folder by double-clicking on it.

Step 7: Find the appraiserres.dll file and right-click on it. From the context menu, select the Delete option.

Step 8: Click on Yes when Windows prompts.

The Windows 11 appraiserres.dll file you see is responsible for checking your computer’s Secure Boot and TPM 2.0. Windows 11 installation will no longer be able to check these features on your PC after you have deleted it. You can install it without any issues.

To upgrade your old Windows 10 to Windows 11, open the setup file and follow the onscreen instructions. After testing, we upgraded our Windows 10 to Windows 11 on Apple MacBook Air. It’s not too difficult.
