I just installed IDBlaster and I am using the defaults with the installation: WMP7 + WMP8 Unique ID, NT -specific ID, Windows ID and Internet Explorer ID. When I edit one of the unique ID's, why can't I click on "Grab Registry Value and Intelligently Format" and have it perform that function on Internet ID or Windows ID or NT -specific ID? Also, how do I determine what ID's I might need to add? I frequently run 2 mp3 download programs (LimeWire and WinMX). Should I add these? If so, how do I find the current ID's? I am running Windows XP Pro, so should I delete the NT entry? This has been confusing to me, so thanks for your help.
