KB2952664 was published on April 22, 2014 and appears in my Windows Update List (I am running Windows 7 Pro - 64 bit).
The description of this update is vague: "This update helps Microsoft make improvements to the current operating system in order to ease the upgrade experience to the latest version of Windows."
Anyone have more information on what this update actually does? If its sole purpose is to ease the "upgrade" from Windows 7 to Windows 8 (or 8.1 or 8.1 update), then I'll just permanently hide KB2952664 (I have no desire or intention to "upgrade" my Windows
7 system to any flavor of Windows 8).
If its purpose is to ease what would be a true Windows 7 upgrade to a yet-to-be-announced Windows 7 SP2, then I'll keep it (but still would like to have more information about what KB2952664 actually does before installing).
