The double-edged fix to “Your system administrator has blocked upgrades on this PC”
I wanted to bring this comment from Mark Berry up to the front, because he nails the problem and its solution quite precisely.
In the discussion about the new name-and-shame messages appearing on domain-joined PCs, Mark says:
The Technet link you posted links to the solution to this problem:

Two “blocks” are required, one blocking Windows Update from installing the upgrade, and the second blocking the little notification icon in the system tray.
If a system administrator implements the first block, but not the second, the upgrade is blocked but not the system tray icon. When the user clicks on the system tray icon, the user sees the message “Your system administrator has blocked upgrades on this PC.”
So the message means exactly what it says: the system admin is not allowing you to upgrade.
If the system admin implements the second block (which must be done by updating the registry), the notification icon will not appear in the system tray, the user will not be able to click on it, and no message appears.
