... why does WU/MU wants me to have them NOW ...
Because Microsoft only just realised that they made a mistake in their WU/MU system.
KB936782 (MS07-047) has always been needed for WMP11 -- if you check the_guy's list you see it listed for XP SP2
AND XP SP3.
On 12-August-2008 Microsoft realised that this update was still necessary but not being detected on SP3. Now it is! You can find this out for yourself if you follow the links that the_guy provides and read security bulletin MS07-047:
QUOTE
Why was this security bulletin revised on August 12, 2008?
Microsoft revised this security bulletin to add Windows XP Service Pack 3 as affected software upon which Windows Media Player 9, Windows Media Player 10, and Windows Media Player 11 run. This is a detection change only; there were no changes to the binaries. ...
Also, don't make the dangerous mistake (as many do) that MU/WU is infallible, or even anywhere near perfect!
