Thanks to goodplay for his post DDU v220.127.116.11
-Windows update is set back to it's default now, so it is mandatory when using DDU to disconnect the internet.
-DDU may be flagged by your AV as a PUA/PUP (potentially unwanted application / potentially unwanted program)
Display Driver Uninstaller (DDU) V18.104.22.168 Released ! | Wagnardsoft
Isn't DDU a safe mode software, so naturally no internet is available
No....when you restart out of safe mode...to install the drivers,,you are connected. Read the post:
-You MUST disconnect your internet or completely block Windows Update when running DDU until you have re-installed your new drivers.
Just set active hours (Win10) to prevent spontaneous updating even for drivers - I remember this was a problem with Win7 but I never saw it on Win10
