Is it possible to enable Microsoft Updates via a registry key, group policy or by downloading & installing a separate package to 'flip the switch'?
To clarify, I'm not talking about enabling 'Automatic Updates'. By default systems get Windows Updates, but I want to get Microsoft Updates to get updates for all Microsoft applications (The Office Suite, Visio, Project etc).
UPDATE: This is solved. The given solutions further below will work. I'll just point everyone to this excellent Microsoft article:
