The only way I know of to get around this whole update business is
to run a virtual machine. This is what I've done since I use a Zune
which requires the runtime11 update.
So if you have an XP disc, download virtualbox and install xp as
a virtual machine.
Once the install is complete, you don't have to do the first part of
mil0tis's instructions, just install wmp10 and finish from there.
