I enjoy sharing troubleshooting tips and advice to help solve various technical issues.
Here's how to install Windows 11 on a computer that doesn't have a TPM 2.0. There is a workaround, even if it isn't officially supported.
Windows 11 is now available for download.
Microsoft unveiled its new operating system on June 24 at a special event, with a major redesign and native support for Android apps among the most notable features.
It's planned to be introduced in October, with a free upgrade available in early 2022 for compatible devices. However, the list of PCs that will receive Windows 11 differs significantly from the list of PCs that are now running Windows 10. Existing devices will have to meet a new set of criteria to be eligible now that Microsoft has changed the hardware requirements.
A CPU that supports a TPM 2.0 module is one of them. TPM 2.0 was released in October 2014, so it excludes a lot of older gear.
Microsoft's 'PC Health Check' tool, which was only available for a short time on the Windows 11 website, incorrectly said that some eligible PCs couldn't run the new operating system. TPM 2.0 was just required to be enabled in the BIOS settings.
The most frequent way to access them is to hold down Esc, Del, or a function key (typically F2) while the device is turning on, with the TPM option commonly identified as ‘PTT' or ‘PSP fTPM'.
However, don't rush out to buy new hardware if you don't have a TPM 2.0 CPU.
There is a technique to get around it, as well as the 4GB RAM and Secure Boot requirements, but it necessitates registry adjustments. As a result, we don't suggest it as a primary device.
How To Get Windows 11 Without TPM 2.0?
This strategy entails creating a lab-like setting. Device manufacturers will be able to disable the TPM requirement on their version of Windows 11 - you'll be able to do the same here:
- Download and Install the Windows 11 beta on any device you want
- Restart your computer and try to install. If your computer doesn't fulfil the system requirements, you'll get a notice that says, "This computer can't run Windows 11."
- Now, open CMD prompt. To open the Command Prompt window, press Shift + F10 from this screen
- Enter the command ‘regedit'
- The Registry Editor in Windows will now open. Type ‘HKEY LOCAL MACHINESYSTEMSetup' into the address bar and press Enter
- A ‘Setup' key should now appear. Choose New > Key from the context menu when you right-click it
- You'll be asked to give it a name now. Name it ‘LabConfig' and press Enter
- Choose New > DWORD (32-bit) value from the context menu of the newly formed key
- Give it the label ‘BypassTPMCheck' and the value 1 for the data
- With the same value of 1, repeat the operation for ‘BypassRAMCheck' and ‘BypassSecureBootCheck.
- Use the red X in the top-right corner to close this window
- Type ‘exit' and hit enter to quit the Command Prompt window
- You'll now get the notification "This PC can't run Windows 11." In the top-left corner, click the back button.
- You should be able to finish the installation normally now.
