Windows 11 is out now. Microsoft announced its new operating system at a dedicated event on 24 June, with a big design overhaul and native support for Android apps among the most significant changes.

It's available to download as of 5 October, although most Windows 10 devices will be waiting until 2022 for the free upgrade to appear. However, there's an easy way to get Windows 11 now on all compatible devices.

Microsoft has updated the hardware requirements for Windows 11. Not all Windows 10 devices will be eligible, as they have to meet a new set of criteria. See more in our separate guide: Will my PC run Windows 11?

Among them is a CPU with support for a TPM 2.0 module. That counts out a lot of older hardware, as TPM 2.0 was released in October 2014.

Microsoft’s has updated its ‘PC Health Check’ app, which tells you if your device will work with Windows 11 - it's available via the Windows 11 website. However, there's still a chance it'll say your computer isn't compatible, when in reality TPM 2.0 isn't enabled.

This can be changed by heading to the BIOS (or UEFI) settings for your device. Holding down Esc, Del or a function key (often F2) while the device is powering on is the most common way to access them, with the TPM option usually described as ‘PTT’ or ‘PSP fTPM’.

However, even if you don’t have a TPM 2.0 processor, don’t rush out to buy new hardware. There is a way to bypass it, alongside the 4GB RAM and Secure Boot requirements, but it involves making changes to the registry. As such, we'd highly recommend backing up all your files and other data first.

How to get Windows 11 without TPM 2.0

This method involves setting up a lab-like environment. Microsoft will allow device manufacturers to disable the TPM requirement on their version of Windows 11 – you'll be doing the same here:

  1. Head to the official Windows 11 download page to get the new OS now - there are three options to choose from
  2. Follow the step-by-step guide
  3. If it doesn’t meet the hardware requirements, you’ll see a message saying ‘This PC can’t run Windows 11’
  4. From this screen, hit Shift + F10 to open the Command Prompt window
  5. Type ‘regedit’ and hit enter
  6. The Windows Registry Editor will now open. In the address bar, type ‘HKEY_LOCAL_MACHINE\SYSTEM\Setup’ and hit enter
  7. You should now see a ‘Setup’ key. Right-click it and choose New > Key

  8. You’ll now be prompted to give it a name. Choose ‘LabConfig’ and hit enter
  9. Right-click the new key you’ve created and choose New > DWORD (32-bit) value
  10. Give it the name ‘BypassTPMCheck’ and set its data to 1

  11. Follow the same process for ‘BypassRAMCheck’ and ‘BypassSecureBootCheck’, with the same value of 1

  12. Close this window using the red X in the top-right corner
  13. Close the Command Prompt window by typing ‘exit’ and hitting enter
  14. You’ll now be back at the ‘This PC can’t run Windows 11’ message. Click the back button in the top-left corner
  15. You should now be able to complete the installation as normal

It’s worth noting that following these steps could affect the performance or stability of Windows 11. Proceed with caution, and try it on a device other than your main PC if possible.
