I know there´s no need to rush getting Windows 10 as I should receive it for free in the future, at least according to what I´ve read.
However, information about the upgrade offer popping up in the taskbar tray icon area are showing up and I didn't get those yet.
I think I found the reason. My 3 PCs are members of a small private Active Directory, all are Windows 8 Pro, upgraded to Windows 8.1 and have genuine keys applied to them. Opening the config in "C:\Windows\System32\GWX" shows, that the following value is set:
<EnableDomainJoined>false</EnableDomainJoined>
The file is write protected and can only be edited as an Administrator. Doing so and setting that value to true I am still not getting the icon. I tried running the GWX executable before and after running the pre-defined scheduled tasks "Microsoft/Windows/Setup/gwx*".
There's another value, where the current phase is defined. I´ve set the following to "AnticipationUX" since for that phase "TrayIcon" is defined as true.
<Phase>None</Phase>
This didn't change anything either.
Does anyone know how to activate the upgrade offer on PCs that are members of a domain? I don't want to take the PCs out of it just for this.
