previusly from xp, i recently switched over to vista ultimate sp0. i'm using office 2003 for my wordprocessing. in xp i wasn't facing any problems using office 2003 or for that matter any other software. in vista though, everytime i click on something (say, start>run, or win+E, or just about anything), a message box pops up saying "windows is configuring microsoft office 2003 professional edition" and then when it completes the configuring for a minute or two, it goes off. again when i start explorer or documents or click on start>run (or anything) the same msgbox pops up. this happens everytime i click my mouse and select anything or key in any windows shortcut key. though my system isn't harmed in any way, but it has become annoying to all of us using one pc for our jobs.

i tried switching windows installer service (services.msc) to disabled. but that prevents any software installation. so i've to reenable that for installation and then disable afterward. all my office 2003 setup files are cached in c:\msocache. one of my tech friends suggested i upgrade to office 2007 but i hate office 2007 because it isn't user friendly at all. so i'm stuck up with this annoyance.

i would greatly appreciate help in this regard.
