Please note there are below requirements before starting the installation / upgrade to Windows 11:
|Processor||1 gigahertz (GHz) or faster with 2 or more cores on a compatible 64-bit processor or System on a Chip (SoC).|
|RAM||4 gigabyte (GB).|
|Storage||64 GB or larger storage device Note: See below under “More information on storage space to keep Windows 11 up-to-date” for more details.|
|System firmware||UEFI, Secure Boot capable. Check here for information on how your PC might be able to meet this requirement.|
|TPM||Trusted Platform Module (TPM) version 2.0. Check here for instructions on how your PC might be enabled to meet this requirement.|
|Graphics card||Compatible with DirectX 12 or later with WDDM 2.0 driver.|
|Display||High definition (720p) display that is greater than 9” diagonally, 8 bits per colour channel.|
To check if you are meeting all the requirements for Windows 11 installation, Download and Install PC Health Check App and click on Check now button. If you are meeting all the requirements that’s great, you can start the upgrade process.
But as we know there are a lot of systems which are not meeting the CPU or TPM requirements, you can follow the steps as given in the next sections of this article to bypass this requirement.
Also, If you have TPM 1.2 and your laptop is compatible with TPM 2.0 then you can upgrade it using BIOS security settings. Please check the next section on how to upgrade it. If Secure Boot is disabled on your system, you can enable it via BIOS.
Upgrade TPM level from TPM 1.2 to TPM 2.0 and enable secure boot
If you are using TPM (Trusted Module Platform) 1.2 and want to upgrade it to TPM level from 1.2 o 2.0. First you need to check if your laptop / desktop is compatible with TPM 2.0.
If yes, then you can change BIOS security settings from TPM 1.2 to TPM 2.0. If your local drives are encrypted with Bitlocker, disable bitlocker and decrypt your drive before the upgrade. Also, make sure to take a backup copy of all your data before taking this action.
- Restart the machine and press F1 to enter into the BIOS mode. Go to Security tab and using your keyboard select Security Chip and Press Enter.
- Check the Security Chip Type to see if you can change the TPM level from 1.2 to TPM 2.0. On my laptop it was set to TPM 1.2 which i updated it to TPM 2.0.
- To check the Secure Boot, Go to Security tab -> select Secure Boot and press Enter.
- Make sure Secure Boot is Enabled.
If you are not meeting the TPM 2.0 or CPU requirements then below registry entry needs to be created to bypass the TPM or CPU checks. You will still require TPM 1.2 at least to proceed with the installation. During Windows 11 setup process, a warning message will be shown, click on Accept to continue with the installation process.
Steps to create registry entry (Please note that you will require administrator rights on the PC to make changes in the registry and your system will require a reboot after the registry entry is created)
- Click on Start and search for Registry Editor.
- Navigate to HKEY_LOCAL_MACHINE\SYSTEM\Setup\MoSetup.
- Create a REG_DWORD registry entry
AllowUpgradesWithUnsupportedTPMOrCPUand set its value to 1.
Once the registry entry is created and you start the setup process to install windows 11, you will receive below Warning message to state that your PC doesn’t meet the minimum system requirements for running Windows 11. Click on Accept and then click on Refresh to proceed with the installation of Windows 11.
- Make sure to use PC Health Check App to check if your device is compatible before upgrade to Windows 11.
- If Device is not compatible w.r.t. TPM or CPU then create a reg key as I had mentioned earlier in this post. This will bypass TPM and CPU checks.
- Fix for 0x800F0830 – 0x2003 – The Installation failed in the SAFE_OS phase with an error during INSTALL_UPDATES operation.
