Yesterday we reported that KB3035583
has been re-enabled on a number of Windows 7 PCs in order to force the Windows 10 upgrade and it turns out that another patch is responsible for all of this.
Basically, Microsoft has rolled out another update that enables KB3035583, which in its turn activates the Get Windows 10 app and displays upgrade nags on Windows 7 and 8.1 computers.
The update in question is KB3150513 and is aimed at both Windows 7 and 8.1. Its purpose is to prepare computers running any of these two OS versions for the upgrade to Windows 10, but in order to do that, it has to un-hide the original KB3035583 patch that Microsoft uses for upgrade distribution.
The description that Microsoft offers in the KB page doesn’t include too many details, though:
“This update provides updated configuration and definitions for compatibility diagnostics performed on the system. The updated definitions will improve accuracy and help enable Microsoft and its partners ensure compatibility for customers who want to install the latest Windows operating system. This update will be offered only if KB2977759, KB2952664, or KB2976978 is installed on Windows 8.1, Windows 8, Windows 7 Service Pack 1 (SP1), or Windows 7 RTM.”
