Windows XP and Vista users in the last few weeks have discovered that Windows Update, the software that automatically checks and installs new updates from Microsoft, was updating files on their machines even when they set the update to "manual". This seems pretty fishy at first, but it should really make no difference to the average user. It only updates Windows Update itself, not the updates that WU fetches from Microsoft. Although there are slight security implications here, all in all it's not a huge deal. [Yahoo - Image Credit]
