How To Easily Create A Custom Windows 11 Install That Skips TPM And Other Requirements

Windows 11
Microsoft is understandably excited about Windows 11, but at the same time, it is taking a more cautious approach to its roll out with a few interesting restrictions. Chief among them is Trusted Platform Module (TPM) 2.0 support. This is semi-mandatory, but what if you have a slightly older PC without TPM 2.0 support? There's an easy way to bypass the requirement using the latest version of Rufus, a popular utility for creating bootable USB flash drives.

Before you embark down this road, understand we are not necessarily recommending you attempt to skip past any of Microsoft's requirements or recommendations, we're merely pointing out how you can, if you so choose. And also before you begin, check out our guide on how to get your PC ready for Windows 11 for steps we do recommend taking.

Here's the thing about Windows 11—Microsoft is aiming to make things more secure and stable (or at least that's the public reasoning) by somewhat enforcing stricter requirements, including support for TPM 2.0 and Secure Boot. There are other requirements as well, including what kind of CPU you need and how much RAM and storage.

If you fall short of the requirements, Windows Update will not attempt to push out Microsoft's latest OS, and will instead keep you up to date with Windows 10. However, you can essentially trick Windows 11 into installing on unsupported hardware by editing the system registry, and Microsoft even provides guidance on how exactly to do that. However, you can break things by mucking around in the registry, so extra caution is required.

Turns out there is an easier way, at least for some of the requirements, and that is where Rufus comes into play.

How To Use Rufus To Make Install Windows 11 While Skipping Over Certain Requirements

The developer of Rufus recently published version 3.16 beta 2, and with the latest beta build comes a new Windows 11 "Extended" installation option. According to the release notes, enabling this option disables checks for TPM 2.0 and Secure Boot support, as well as perhaps the RAM requirements.

We're not real clear on the RAM part, because the utility claims Windows 11 requires 8GB of RAM, whereas Microsoft lists 4GB of RAM. In all reality, 8GB is a good baseline for running Windows, and going under 4GB is likely a recipe for frustration. In any event, the option is there to bypass the check.

Keep in mind that beta software is not always stable. That said, we didn't have any trouble with the latest Rufus beta, but of course your mileage will vary. In any event, here are the steps...
  1. Back up any important data, which is something you should always do when upgrading your OS. That includes whatever is on the USB flash drive you intend to use, because it will be wiped if you proceed.
  2. Download Rufus 3.16 beta 2 from GitHub (or a later version if one is available).
  3. Download the Windows 11 Disk Image (ISO) from Microsoft's website.
  4. Plug a USB flash drive into your PC and run the Rufus utility.
  5. Choose your USB flash drive from the Device heading if it doesn't appear automatically.
  6. Under the Boot selection heading, choose the Disk or ISO image (please select) option, then click Select and choose the Windows 11 ISO you downloaded.
  7. Under the Image option heading, select Extended Windows 11 installation (no TPM/no Secure Boot/8GB- RAM) option.
  8. Leave everything else at their default selections and click Start to create your custom installation media.
Whatever you had on your USB flash drive prior to doing this will be lost forever (barring a successful run with an undelete utility), so absolutely make sure you follow the very first step (back it up!).

This is a fairly quick process, minus however long it takes to download the Windows ISO from Microsoft. After clicking the Start button, it took around a minute to complete on our system with an older Toshiba 128Gb EX II flash drive.

One additional word of warning—after it's finished, Rufus warns that you need to disable Secure Boot, if applicable, in order to install Windows 11 from your newly created media. The developer says that's not because the bootloader is unsafe, but only because Microsoft "has unilaterally decided, for no reason that stands the test of scrutiny, that anything licensed under GPLfv3 cannot be signed for secure boot, ever."

So there you have it. Good luck!
