Sorry DavidPK,
Those reg keys are not authoritative. The only documented and supported programmatic approach according to Microsoft is checking ESU with WMI.
Microsoft does not publish any official registry-based method for confirming ESU activation in enterprise environments.
ESU activation is handled by the Software Protection Platform which stores license data in encrypted tokens not in a simple registry Dword. All of Microsoft's official deployment guides use WMI or slmgr.vbs never registry checks.
Please help us identify a way for us to report on ESU for Enterprise windows 10 in lansweeper.
