thanks by advance.

This is one of the methods that people were sharing/discovered a while back. This works by attempting to block the DX12 DWM check that MS added to try and prevent things from running DX12 if an older OS is detected. (I cannot confirm these files work or are safe, use with caution and test in a VM etc.)

Keep in mind this may also require some additional work to the specific app/game too though depending on how its compiled and what libraries it uses. They may compile against a runtime that is designed for Windows 10 and has Win10 only API that you will either need to remove/bypass/emulate/etc. as well. They may also add their own checks for which OS is currently present to try and limit the game from running.

As an example, here is a project of mine that bypasses an application's limitation from running on anything but Windows 10. This is for Elgato's StreamDeck hardware/software. Elgato has the installer limited to only work on Windows 10 and also prevents the app from running properly in multiple ways. They attempt to block the app from working if it does not see its on Windows 10, it also does not show any plugins in the available list based on the OS information.

This is limited based on them using a newer version of Qt that is made for Windows 10 and also has its own code in place to check for a Windows 10 machine and not work for anything else.

My project emulates some of the API calls to fake which info is returned to make the software assume its Windows 10 and so on.
