If your PC doesn't have TPM, it is still possible to install Windows 11 without TPM 2.0 chip.
1. Press Win + R, type regedit, and press Enter.
2. Go to:
HKEY_LOCAL_MACHINE\SYSTEM\Setup\MoSetup
3. Right-click the right pane → New > DWORD (32-bit) Value → name it:
AllowUpgradesWithUnsupportedTPMOrCPU
4. Double-click it and set the Value data to 1.
5. Close the Registry Editor.
6. Run the Windows 11 Setup.exe from an ISO or USB created with the Media Creation Tool.
7. Choose Keep personal files and apps to upgrade safely.
