With your help I was able to restore win 8.1 OEM and finally upgrade to win10!
 I was able to use reagentc /setosimage directly from win 10 and then build the win8.1 recovery usb

It has been said by MS that /setosimage was deprecated  in Windows 10, But it does not appear to be the actual case..
Windows 10 does not use a factory recovery image per say - it uses the component store (winsxs) and a provisioning package to reset Windows 10...

But it appears that Reagentc can still be used to direct Win10 recovery to use a factory install.wim

If your Host OS is Windows 10
You run reagentc /setosimage > pointing to the factory windows 8.1 recovery image
You create a recovery drive from within the Host Windows 10 OS
you boot from the recovery drive
and RESET Windows 8.1

and RESET Windows 8.1
Thanks,

from my experience last 2 years with Windows 8.1 , I am sure many users need to switch back to Win8.1,
 I left "Get Windows 10" on taskbar alone  :grin:
  In real life, many "big or complex , task specific " utilities can not update their files/programs as fast as Windows,
   and MS breaks compatibility badly especially at driver level....
    That is the reason I see developers slowly moving to "not use .sys where possible" way.

I am sure real life users would need to RESET Windows 8.1 If they "Get Windows 10"   :thumbsup:
 Thanks for the info  :great:

Yes, Win10 still has a long way to go and many, way to many reported issues...
I have Win10 within VHD - just for reference testing..
Had 10 on Host and did not like it - reverted back to 8.1
Activated free Win10 upgrade on all other PC's via VHD
Once 10 activated it is activated for life of PC
