Just replaced motherboard on my old Dell D830 that I had upgraded to Windows 10 Pro from Windows 7 Pro last August.
Went through steps on setting up new MOBO and it is up/working just fine.
I happened to run Belarc Advisor just to get a snapshot of data for the file. What is interesting is that Belarc indicates the O/S is Windows 8 Pro (build 9200).
I looked at another recent thread here at TenForums and also took some of the steps suggested and figured that maybe I needed to install or re-install Windows 10. I checked the Update/Security/Activation tab and it indicates that Windows 10 Pro is installed, activated with a digital entitlement.
So ... why does Belarc seem to see only Windows 8 Pro? Maybe because of the "maturity" of the D830? I know that Dell has disclaimers at their site that says the D830 has not been certified for Windows 10.
So, it is working, but the data from Belarc just has me scratching my head.
Any suggestions or thoughts?
