did u use DDU?
do you have intel chipset?
if yes, you have to UNTICK "prevents downloads of drivers from Windows update..." in the tab options.
this is to avoid windows from blocking the update of the intel drivers to 18.104.22.168x, which are now compatible with w10 1809 and amd.
once u have updated Intel, u can do the same with amd and radeon settings WILL open.
should w10 automatic update still try to download a very old amd driver after this, than download "wushowhide" from microsoft site in order to hide unwanted update (works for 6 months, after that re-run the program, also: remember to reboot the system as u use this or it will download old drivers anyway in that session).
