Bypass Windows 11 Requirements – Fix TPM, Secure Boot & RAM Error
introduction
We recently set up a Sangfor HCI (Hyper-Converged Infrastructure) cluster for testing and ran into the "This PC can't run Windows 11" error while trying to install Windows 11. Here is the solution we'd like to share with everyone.
After creating a new VM in Sangfor HCI and following the standard steps to install Windows 11, we hit an error: "This PC doesn't meet the minimum system requirements to install this version of Windows. https://aka.ms/WindowsSysReq"
This happens because of missing:
-
🔐 TPM 2.0
-
🛡️ Secure Boot
-
💾 4GB+ RAM
-
💽 64GB storage
-
🧠 Supported CPU
According to Microsoft, these requirements enhance system security. However, many older PCs can still run Windows 11 smoothly after bypassing checks.
The Solution:
On the Windows 11 installation screen, press Shift+F10 to open the command prompt, then enter the following three commands:
REG ADD HKLM\SYSTEM\Setup\LabConfig /v BypassTPMCheck /t REG_DWORD /d 1
REG ADD HKLM\SYSTEM\Setup\LabConfig /v BypassRAMCheck /t REG_DWORD /d 1
REG ADD HKLM\SYSTEM\Setup\LabConfig /v BypassSecureBootCheck /t REG_DWORD /d 1
The first command bypasses the TPM 2.0 check, as many older computers don't have a TPM 2.0 security chip.
The second command bypasses the RAM check; the official requirement is at least 4GB, but this command lets you ignore that.
The third command bypasses the Secure Boot check, allowing installation even if Secure Boot isn't enabled on older motherboards or BIOS.
Using these three together means:
Ignoring TPM 2.0, ignoring RAM size, and ignoring Secure Boot to force the Windows 11 installation.
Once entered, you can proceed with the installation normally:
And that’s how you fix the issues encountered when installing Windows 11 on Sangfor HCI.
