Requirement: -Windows XP up to Windows 10 Creator update 1703 (anything higher is at your own risk) -NVIDIA, AMD, Intel GPUs -Microsoft .NET Framework 3.0 or higher Recommended usage: -You should disconnect your internet or block Windows Updates. -DDU should be used when having a problem uninstalling / installing a driver or when switching GPU brand. -DDU should not be used every time you install a new driver unless you know what you are doing. -The tool can be used in Normal mode but for absolute stability when using DDU, Safemode is always the best. -If you are using DDU in normal mode, Clean, reboot, clean again, reboot. -Make a backup or a system restore (but it should normally be pretty safe). -It is best to exclude the DDU folder completely from any security software to avoid issues.
