MS SQL
Following on from my XP Updates thread, I find I have a plethora of MS SQL bits under 'add/remove'. I cannot recall why I installed them now - if I did. 'Scuse my ignorance, but what is the function of the MS SQL bits and pieces and do I actually need them at all/what do I need it for? Can they all be uninstalled and reloaded if it turns out I need them or will the world come crashing down at my feet?
