Microsoft now requires that a computer have a TPM 2.0 to install Windows 11. However, new registry entries have been discovered that allow you to bypass the TPM requirement and the minimum memory and secure boot requirements.
With Windows 11, Microsoft added new minimum system requirements so that all devices need a TPM 2.0 security processor to power some of the operating system’s security features.
“The following Windows features require TPM 2.0: Measured Boot, Device Encryption, WD System Guard, Device Health Attestation, Windows Hello / Hello for Business, Platform Crypto Provider Key Storage TPM, SecureBIO, DRTM, vTPM in Hyper-V, ”Microsoft said Bleeping Computer.
For most people using processors created within the last 5-6 years, a firmware-based TPM (fTPM) is built into the processor and can be enabled in the BIOS.
To enable fTPM, simply boot your computer in BIOS and enable Intel Platform Trust Technology (Intel PTT) or AMD Platform Security Processor, depending on your CPU.
For those who do not have this feature, you may be able to install a discrete TPM 2.0 processor on the motherboard. However, if your processor is old enough that it doesn’t have fTPM built-in, your motherboard module will likely be TPM 1.2, which is not compatible with Windows 11.
This requirement is frustrating for users running Windows 10 on older equipment, as they are now forced to purchase new hardware to install Windows 11.
Moreover, as Microsoft has indicated in the documentation that OEMs can get permission to disable the TPM requirement in Windows 11 for their devices, the question becomes: do you really need a TPM 2.0 processor to use Windows 11?
How to bypass the TPM requirement in Windows 11
If you try to install Windows 11 and receive a message that says “This PC cannot run Windows 11”, it is likely that you have not installed or enabled TPM 2.0.
The good news is that Microsoft is including a new “LabConfig” registry key that allows you to configure settings to bypass TPM 2.0, 4 GB memory, and secure boot requirements.
Based on the name of this registry key, it is likely used by Microsoft or OEMs to set up a “lab” environment for testing Windows 11 on older equipment or when testing new features.
To bypass TPM 2.0 requirements when installing Windows 11, please follow these steps:
- Install Windows 11 through an ISO or the Windows 11 Insider program. While installing Windows 11, if your computer does not meet the hardware requirements, you will see a message that says, “This PC cannot run Windows 11”.
- When you see the above message, press Shift + F10 on your keyboard at the same time to launch a command prompt. At this command prompt, type regedit and press Enter to launch the Windows registry editor.
- When Registry Editor opens, navigate to HKEY_LOCAL_MACHINE SYSTEM Setup, right click on the To install button and select News > Key.
When prompted to name the key, enter LabConfig and press Enter.
Now right click on the LabConfig button and select News > DWORD value (32 bit) and create a named value BypassTPMCheck, and set its data on 1. Now create the Bypass RAMCheck and BypassSecureBootCheck values and set their data to 1 so, so it looks like the following picture.
- Once you have configured these three values under the LabConfig key, close the registry editor, then type to take out in the command prompt followed by Enter to close the window.
- You will now be back to the message that the PC cannot run Windows 11. Click the Back button in the Windows Setup dialog box as shown below.
- You will now be back to the screen prompting you to select the version of Windows 11 you wish to install. You can now continue with the setup and the hardware requirements will be skipped, allowing you to install Windows 11.
It is important to note that disabling these features can affect the performance or stability of Windows 11, so make sure you only use them on a virtual machine or test box that is suitable for you to work in an unsupported environment. in charge.
Additionally, by disabling the TPM 2.0 requirement, you effectively reduce security in Windows 11.
Finally, running Windows 11 on less than 4 GB will not be an optimal experience and is not recommended.
