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.
