Can someone tell me what the advantage is in using the Windows Update Downloader as opposed to just plain ole Windows Updates?

WUD downloads ALL of them en-masse, just like UDC for XP (http://xdot.tk/) will.

Windows Updates will give you obsolete (superseded) Updates -and- is SLOOOOWWWWW!

The intent of WUD/UDC is to create/slipstream a fully-up-to-date Install CD/DVD. Windows Update is strictly to Update a Running OS.

(note I reference XP, but there are methods for other-than XP)

 

edit - You may ALSO note that you MAY have to repeatedly go to WU to get ALL of the Updates. Note ALSO that -some- folks prefer to NOT have AutoUpdates on and ALSO to be able to update an OS off-line (not connected to the web).
