I did some additional analysis as outlined below.
#AMD RYZEN MASTER BLUE SCREEN ON STARTUP WINDOWS 10 HOW TO#
In effect, this device is now missing: how can I recover this entry in Device Manager or is it not necessary? Any clarification how to correct (or ignore) would be appreciated. However, I also noticed that in Device Manager > System Devices the device listed under 'AMD RyzenMaster Device' (if I recall correctly) was showing troubles (triangle/exclamation mark, error 19 with reference to a wrong registry entry) and I decided to uninstall it assuming it would be re-established after another uninstall/reinstall of AMD Ryzen Master however, it did not also not with a scan for new hardware (and is also not hidden). Apparently these are automatically generated upon restart and/or reinstallation and the one does not go without the other and AMD Ryzen Master now works fine. I deleted the key in registry (suggestion that I found on many places) and that did not work until I amended the key by deleting "\?\" with which the ImagePath started uninstalling and installing AMD Ryzen Master in the end leaves me with two almost identical registry keys (both with an ImagePath starting with "\?\") one 'AMDRyzenMasterDriver' and one 'AMDRyzenMasterDriverV19'.

Unfortunately this also resulted in the very same "Ryzen Master not installed properly.

After an unsuccessful update of AMD Ryzen Master I decided to uninstall it and go for a clean install (2.).
