How to Upgrade HP 8200 Elite CMT to TPM 2.0 for Windows 11

Select Language:

If you’re trying to upgrade your HP 8200 Elite CMT to Windows 11, you might be wondering whether you’ll need a TPM 2.0 chip. The truth is, there’s no way to upgrade the TPM 1.2 hardware on this model to version 2.0 because it’s a physical component that can’t be changed through firmware updates. The oldest HP desktop in the Elite series that supports a TPM 2.0 upgrade is the EliteDesk 800 G2.

Even if it were possible to upgrade the TPM, your HP 8200 Elite CMT still wouldn’t meet Windows 11’s official requirements because of other hardware limitations. This model uses Intel 2nd Generation Core processors, while Windows 11 officially needs at least an 8th Generation or newer. Additionally, the system uses an older BIOS or UEFI that doesn’t fully support Secure Boot, another key requirement for Windows 11.

However, if upgrading hardware isn’t an option, don’t worry — you can still upgrade your PC to Windows 11 through some reliable workaround methods. One popular method involves modifying the Windows 11 installation process using a simple trick. There’s a YouTube guide that walks you through this process clearly and easily: Watch the tutorial here.

This method uses a clever backdoor that Microsoft created for server installations, which can be adapted to work with Windows 11. It’s a straightforward approach that has worked well for many users, including myself, on older HP desktops without any problems.

The key part of this fix involves changing just one file during the installation: replacing the “appraiserres.dll” file with the version from Windows 10. This small change disables the checks for TPM, CPU, and Secure Boot, allowing you to install Windows 11 without meeting the usual hardware requirements. As long as Microsoft doesn’t change how the installer works in future updates, this trick should remain one of the quickest shortcuts around unsupported hardware.

If you try Windows 11 and decide it’s not for you, you have 10 days to revert back to Windows 10 without too much trouble. After that period, you might need to do a fresh install to switch back, unless you follow the detailed steps in another easy-to-follow YouTube tutorial here: Rollback to Windows 10 tutorial.

Remember, these workarounds are meant to help you get Windows 11 running on older machines that don’t technically meet the requirements, but proceed with caution and be aware that modifying system files can carry some risk.
