OCS Agent dectectinf Windows 10 as Windows 8

[fgendorf]

Reference issue #232

General information

Operating system : Windows 10 10.0.19044

OCS Inventory information

Windows agent version : 2.10.1.0

Problem's description

Sometimes the OCS agent send to server the information that Windows 10 are a Windows 8.... I checked and I can see WMI are OK, but the machine was on lockscreen on monitor and another user accessing trough RDC.

We also have this problem.

My five-minute-analysis (please correct me if I am wrong):
It seems the OCS windows agent uses dtwinver (http://www.naughter.com/dtwinver.html) to detect the OS: https://github.com/OCSInventory-NG/WindowsAgent/blob/master/SysInfo/Dtwinver.cpp - but as you can see here this is from April 2019 (a time where Win10 1903 was current).
So I guess the dtwinver version in OCS agent has to be updated? Or why not read the version from registry or other sources which require no 3rd party library?

Edit:
Ok it seems OCS agent trys to first use WMI and then falls back to dtwinver: https://github.com/OCSInventory-NG/WindowsAgent/blob/master/SysInfo/SysInfo.cpp#L73
So I suppose this is a WMI issue...
