Can I install windows 11 without tpm and secure boot?

[Lana78]

Hi everyone, I've recently been considering upgrading to Windows 11, but my computer doesn't have TPM 2.0 and Secure Boot. I know these are the minimum requirements for Windows 11, but I've seen people mention that these limitations can be bypassed. Can I install Windows 11 without TPM and Secure Boot enabled? If so, are there any steps or tools that can help me achieve this?

Thanks for your help!

Yes, you can install Windows 11 without TPM (Trusted Platform Module) and Secure Boot, but it's not officially supported by Microsoft. Windows 11 has specific hardware requirements, including TPM 2.0 and Secure Boot. However, there are ways to bypass these requirements for installation and let you easily install Windows 11 without TPM and secure boot.

Here is a working method suggested by an expert of Microsoft MVP:

Note: Make sure download Windows 11 ISO from Microsoft website.

You gotta check if your hardware can actually handle Windows 11. Even if you’re skipping TPM and Secure Boot, other requirements like processor compatibility and RAM need to be met. I once tried to push an old laptop past its prime, and let’s just say the result was less than stellar. You don’t want to end up with a sluggish system or constant crashes.

If you're trying to install Windows 11 without TMP and secure boot, you’ll need to dive into the Windows Registry. There’s a specific key you can tweak to allow the installation, but making a mistake here can mess things up. Double-check what you’re editing before hitting save. I'd recommend Googling the exact steps to avoid a faux pas.

Hi, @Lana78 

If you are interested in installing W11 24H2 on your PC as is, watch this video:

How to install Windows 11 24H2 on Unsupported PC (Early Access) 2024 (youtube.com)

Download the W24H2 ISO file and use that (3rd option).   

Download Windows 11 (microsoft.com)

You can download the free 7-Zip file utility from the link below.  The top line is for 64 bit.

You'll have to repeat this procedure each October when Microsoft rolls out the new builds because a PC that does not meet Microsoft's minimum W11 hardware requirements will never automatically get the update to the next build.

Other than that, your PC will continue to get the monthly cumulative and other updates.

That's only a minor inconvenience to have continued OS support beyond October of 2025.

There is no need to modify any registry settings, etc.

The only thing is with W11 24H2 your PC's processor must be able to support SSE 4.2. which most processors made in the last dozen years or so do support.

Installing Windows 11 without TPM and Secure Boot can be tempting, especially if you’re looking to bypass the usual hardware requirements. TPM is designed to make your PC more secure by storing encryption keys and hardware-based authentication. Without it, your PC might be more vulnerable to malware and attacks. Secure Boot, on the other hand, prevents unauthorized software from loading during the boot process. Not having both means you’re essentially leaving the door slightly ajar for potential security threats.

While you mentioned you’d still get monthly updates, it’s important to note that you might miss out on future features or security enhancements that depend on those technologies. Microsoft is likely to lean into using TPM and Secure Boot for new features, which could leave your system a bit in the dark.
