Well it most likely puts a new uxtheme.dll in there I guess?
XP SP3 doesn't have anything in there that should stop it being immediately deployed. I will need to do a bit of messing around (extra nic driver, raid driver for single disk intel array - muppets) and then it should be good to go on our network.
Then I will be stopping my work on XP deployment for ever and ever, handing it to someone else in time for the e-series
I used a customized XPSP2 that included loads of themes. Though as EP said I think that is what it did, updated the uxtheme.dll and I've gotten contact with the person who made the customized install I used to inform him of that but figure it will be a while before it gets fixed and unless I do something to really fubar the install I can live without the themes
