Windows 11 upgrade failed as it says "The PC must support TPM 2.0"

If you're encountering the "This PC must support TPM 2.0" error when trying to upgrade to Windows 11, here are the best ways to fix it:

Update BIOS/UEFI (If TPM Option is Missing)

Some older motherboards need a BIOS update to enable TPM 2.0. Steps:

Check your motherboard model (Press Win + R, type msinfo32, look for "BaseBoard Manufacturer/Model").

Download the latest BIOS from the manufacturer’s website (ASUS, MSI, Gigabyte, Dell, HP, etc.).

Update BIOS (follow manufacturer’s instructions carefully—wrong updates can brick your PC!).

Re-enable TPM after updating.

Install Windows 11 Without TPM 2.0

If your PC doesn’t support TPM 2.0 at all, you can bypass the check (but this is risky—no security updates & potential instability).

Create a Windows 11 USB using Media Creation Tool or Rufus.

During setup, press Shift + F10 to open Command Prompt.

Type:

regedit

Navigate to:

HKEY_LOCAL_MACHINE\SYSTEM\Setup

Right-click → New → Key, name it LabConfig. Inside LabConfig, create these DWORD (32-bit) Values:

BypassTPMCheck = 1

Close Registry Editor and continue installation. This will help you install Windows 11 without TPM on an unsupported PC. And you won't see the error screen (The PC must support TPM 2.0) at this time.
