Hello Haziq Omar,
To stop Windows Update from overwriting your custom Nvidia drivers, you can implement a two-layered defense. First, prevent Windows from including drivers in its update cycle by enabling the Do not include drivers with Windows Updates policy in the Group Policy Editor (for Pro/Enterprise users) or by creating the ExcludeWUDriversInQualityUpdate DWORD value set to 1 within the registry key HKEY_LOCAL_MACHINE\SOFTWARE\Policies\Microsoft\Windows\WindowsUpdate (for Home users). Second, provide an extra layer of protection by searching for Change device installation settings in the Start menu and setting it to No, which stops the system from automatically downloading manufacturer-specific apps and icons that often accompany driver updates.
