Much controversy has come from Microsoft’s decision to restrict Windows 11 to machines that support TPM 2.0, with the company itself even seeming uncertain about the move. We have already shown you how to check if your PC has a TPM chip. Today, we’ll be teaching you how to install Windows 11 without TPM via a recently discovered bypass.
What is TPM?
TPM stands for Trusted Platform Module, which may not mean much to you alone. Essentially, TPM is a security module typically soldered onto the motherboard in the form of a chip. It acts as a cryptographic processor and offers a hardware-based approach to generating hashes and storing cryptographic keys, biometric data, user data, and more.
Rooting the cryptography in hardware makes it all but impossible for attackers to tamper with and access this data, protecting against malware, ransomware, and sophisticated nation-state attacks.
Is it safe to install Windows 11 without TPM?
Despite what Microsoft’s Windows 11 compatibility tool may tell you, installing Windows 11 without TPM is quite simple. All it requires is a few registry entries and five minutes of your time.
Before you do so, however, you should consider that TPM 2.0 is used to power many of Windows 11’s security features. This includes measured boot, Windows Hello, SecureBIO, WD System Guard, and Device Health Attestation. When you run Windows 11 without a TPM chip, you won’t have access to these features and may be putting your data more at risk as a result.
If possible, then, we recommend that you install a discrete TPM 2.0 module or wait and upgrade your hardware. It’s likely Windows 11 will only rely on TPM more in the future and we can’t guarantee that Microsoft won’t disable this bypass once the full version of Windows 11 releases in October.
If you really can’t do the above or just want to take the new OS for a test drive, however, this is how you install Windows 11 on unsupported hardware:
How to Install Windows 11 Without TPM
As mentioned, installing Windows 11 without TPM requires a few registry entries. The easiest way to do this is to try to install Windows 11 via an ISO or the Insider program, then follow the steps below if you get a “This PC can’t run Windows 11” message.
If you see the message “This PC does not meet the system requirement”, minimise the installer, go to registry, edit the entries, then go back to the installer, Press back button once, and continue.
- Press Shift + F10 to open Command Prompt and run the “regedit” command
- Add a new key in the “Setup” key
In the Registry Editor, navigate to
Computer\HKEY_LOCAL_MACHINE\SYSTEM\Setup. Right-click on the “Setup” folder in your sidebar and select “New > Key”.
- Name the key “LabConfig” and add a new DWORD
After you name your folder, you can create the DWORD by right-clicking in any blank space in the main pane and selecting “DWORD (32-bit) Value”.
- Name the value “BypassTPMCheck” and set the value data to 1.
It’s important the capitalization and spelling are exactly the same. You can modify the value data by double-clicking your new DWORD and changing the “Value data” text box. Press “OK” when you’re done to save the changes.
- Create another DWORD called “BypassRAMCheck”
Again, make sure the capitalization and spelling is exactly the same as above.
- Change the value data to 1
Remember, you can access the value data field by double-clicking on the “BypassRAMCheck” key. Press “OK” to apply it.
- Create a new DWORD called “BypassSecureBootCheck”
- Change the value data of SecureBootCheck to 1 and press “OK”
- Close the Registry Editor and press the back button on your Windows 11 setup
You’ll find the back button in the top-left corner.
- Install Windows 10 on your unsupported hardware
You can now go through the setup process as normal. Your installer should no longer tell you your PC is incompatible.
