hp z640 workstation upgrade Windows 11 (bypass) error at 8% does not meet system requirements

It looks like you're facing an issue with upgrading your HP Z640 workstation to Windows 11, where the installation halts at 8% with a message stating that the system does not meet requirements, particularly regarding TPM 2.0 and processor support. Here are some insights and potential fixes for the situation.

Image Analysis​

1. Windows 11 Setup Error Message:
   • The error indicates that your workstation might be lacking TPM 2.0, which is a security requirement for Windows 11. It also mentions that the processor is not supported. The processor compatibility is often tied to the Intel or AMD generations supported by Microsoft.
2. Windows Update Settings:
   • This image details the Windows Update settings available on your PC, showing that an update for Windows 11 (version 24H2) was available, along with options to manage updates.
3. About Windows:
   • This shows the version and build of the current operating system you are running, further confirming that you're attempting to upgrade from a relatively newer version.

Steps to Troubleshoot and Fix the Upgrade Issue​

1. Check TPM Settings:
   • Make sure TPM 2.0 is enabled in your BIOS. You can often access the BIOS during boot by pressing a key like F10, F2, or Del.
   • Look for options under Security settings. If TPM is present but not enabled, you need to turn it on.
2. Processor Compatibility:
   • Confirm that your processor is on the official list of compatible CPUs for Windows 11. If your processor is not supported, bypassing this check could be challenging and might not guarantee a smooth upgrade.
3. Upgrade Method:
   • Use the Media Creation Tool: Download the Windows 11 installation media using the Microsoft Media Creation Tool. This sometimes bypasses restrictions during the installation process.
   • Custom Install: If you boot from the USB created with the Media Creation Tool, choose "Custom Install" which sometimes allows more flexibility.
4. Manual Update Download:
   • If you suspect that the failure may relate to a specific update, you can check Windows Update and download updates manually. Go to the Microsoft Update Catalog (here), search for the required updates by KB number, and download them.
5. Registry Modification (Advanced Option):
   • Note: This method should be used with caution.
   • Some users have found success by modifying the registry to bypass the TPM and processor requirements. You can create a key in the registry before running the upgrade. This involves creating a backup of your registry first.
   • Steps involve:
     • Open Regedit.
     • Navigate to HKEY_LOCAL_MACHINE\SYSTEM\Setup.
     • Right-click on Setup, select New > Key, and name it LabConfig.
     • Within LabConfig, right-click and add the following DWORD (32-bit) values:
     • BypassTPMCheck set to 1
     • BypassRAMCheck set to 1
     • BypassSecureBootCheck set to 1
     • BypassCPUCheck set to 1

Important Note​

Bypassing system requirements can lead to performance issues, lack of updates, or stability problems. Ensure that you have backups of your important data before proceeding with any modification to your system.
