  • Press the power button on the computer to turn it on, and immediately press the “F2” or “Delete” key on the keyboard. You can also do this by restarting your PC.
  • If the timing of pressing the key is not correct, the BIOS will not start, so it is more reliable to repeatedly press the key until the BIOS screen appears.

 Disabling the TPM feature

1. Click “Advanced Mode” on the UEFI BIOS boot screen.

* Advanced Mode is a mode in which detailed settings can be made.

 2. Click Advanced in the top menu.
 3. Click “PCH-FW Configuration” in the setting items.
 4. Click the box for Intel Platform Trust Technology and select Disable. 

The name of the setting differs depending on the CPU.
There are two types of names for TPM settings on CPUs currently used in Windows:

  • For Intel, ” PTT (Platform Trust Technology)”
  • For AMD, ” fTPM(firmware TPM)”

5. A warning about BitLocker will appear, click OK.

Clicking OK here does not finalize the settings. 

6. Click Exit on the menu.
 7. When the exit method is displayed, click “Save changes and reset”.
 * To cancel disabling the TPM, click “Exit without saving”. 8. After the PC restarts and Windows boots, the TPM is disabled.

Confirm TPM Disable

1. Right-click the Start button and click “Device Manager” in the menu.  2. If you can’t see “Security Devices” in Device Manager, you have successfully disabled the TPM.
 With this, the prompt to upgrade to Windows 11 is not displayed, and the upgrade stop is completed.

Mechanism and precautions to stop Windows 11 upgrade

One of the requirements for Windows 11 is the installation of ” TPM (encryption)”. So, by disabling the TPM, it changes to a computer that does not meet the requirements and completely stops the Windows 11 upgrade. After disabling the TPM, in the requirements check, “Windows 11 system requirements are not met” is displayed as shown in the figure below, and the upgrade can be stopped.
 If you upgrade to Windows 11 or do a clean install, just set the TPM to “Enable”. 

Note before disabling the TPM:
If BitLocker (disk encryption) is enabled, disabling the TPM may require entering a recovery key. Do not disable the TPM if you do not know your recovery key. The safest method is to unlock BitLocker before disabling the TPM. Checking whether BitLocker is enabled or disabled and how to unlock the encryption are also introduced in detail on the following page.
