Update:
After several reboots still had the problem!!!!
More investigation and turning services on or off the problem is NOT as above
I turned these services back on since they did not seem to be the issue…..
Final result turned off:
“Steam” (for games) and who I think the culprit is:”Video Performer Manager”!!!
Personally I think the video manager is the issue but for now they are both off and when I get more time on my hands will try to put “steam” back on.
Thanks
David

Here are the files involved from msconfig:

C:windowssyswow64HsMgr.exe Envoke
C:windowssystemHsMgr64.exe Envoke

Both are found in: HKLMsoftwaremicrosoftwindowscurrentVersionRun

thanks again

Thanks jerry
you hit it on the nose
did a clean boot, disabled a file called “HsMgr” not in the Win32 folder and that “fixed” the issue.
the file was in the C:windowssystemHsMgr.exe envoke and HsMgr64.exe Envoke.
not sure if a virus or otherwise, will keep an eye on it
again, Thanks
