Issue "AMDRyzenMasterDriverV27" service

RyzenMaster is not installed. But I get this error in eventmanager on Windows 11.

I'll pull my "solution" for a previous version of that service from:

 

https://community.amd.com/t5/pc-drivers-software/the-amdryzenmasterdriverv22-service-failed-to-start...

 

My error message was slightly different from yours.  So, I don't know if this will work.  But, it might be a starting point.  Also, in the stuff below, I'm asking if I can delete the entries I found.  But, as I said in my final edit, I did delete them and the problem went away.  Hope it helps you:

 

"...If I fire up Sysinternals' Autoruns utility:

https://learn.microsoft.com/en-us/sysinternals/downloads/autoruns 

and filter for AMDRyzenMaster, it shows three places where that stuff is autostarting:

  • \AMDRyzenMasterSDKTask AMDRyzenMasterSDKTask (Verified) Advanced Micro Devices Inc. C:\Program Files\AMD\CNext\CNext\cpumetricsserver.exe Thu Jan 11 12:45:02 2024
  • AMDRyzenMasterDriverV20 AMDRyzenMasterDriverV20: AMD Ryzen Master Service Driver (Verified) Advanced Micro Devices Inc. C:\Windows\system32\AMDRyzenMasterDriver.sys Thu Jan 11 09:21:26 2024
  • AMDRyzenMasterDriverV22 AMDRyzenMasterDriverV22: AMD Ryzen Master Service Driver (Verified) Advanced Micro Devices Inc. C:\Windows\system32\AMDRyzenMasterDriver.sys Thu Jan 11 09:21:26 2024

Right-clicking and doing a "Jump to Entry" for the first entry, above, AMDRyzenMasterSDKTask, that's apparently started in Task Scheduler.  The only trigger I see is "on demand."  It IS running though, but I don't know what's initiating it.  Can I just delete that scheduled task since I no longer have Ryzen Master installed?

The last two entries, AMDRyzenMasterDriverV20 and V22 are both started in the Registry at:

Computer\HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services

Besides their very existence, the only odd thing I see is their ImagePath.  They both point to C:\Windows\system32\AMDRyzenMasterDriver.sys (which DOES exist).  But, their paths are preceded by question marks:

\??\C:\Windows\system32\AMDRyzenMasterDriver.sys

Can I safely delete those?

EDIT:  Well, I've deleted all three of those autostart task and, so far, no smoke has been emitted from my computer.  So, I'll tentatively say it's OK to delete them."
