The core issue on Windows 10 is often related to driver installation. Many discussions on tuning forums, such as MHH Auto, revolve around this problem.

This can be done by restarting the PC and pressing a specific key (like Shift) to access advanced startup options or by putting Windows into "Test Mode". More advanced users even resort to using a Windows 7 installation on newer PCs for reliable operation, as they perceive Windows 10 as problematic for this task.
