You could try installing the additional MS service, UPHClean That can help with slow shutdowns in some cases.   [URL]   SECOND ATTEMPT TO POST THIS
I did a clean install of Windows XP Pro SP2 with all drivers from the Dell site. No problems occurred. The last thing I installed was the driver for the wireless card. After this shutdown of windows is significantly delayed.From the message "Windows is being shut down..." (I have German Windows. I don't know the exact words of English Windows) to power off it takes4 seconds without wireless driver22 seconds with wireless driver.This is reproducible.I have the impression that Windows reacts slightly "sticky" after wireless installation. I mean, actions "feel" slightly delayed. However, this is just an impression, maybe due to growing paranoia. If at all, the effect is next to nothing.There is no excessive CPU activity.
