hi,
3 questions please:
1 - do i need to retain the files in "Download History"?
2 - i don't usually play CD's on my computer. will i cause any problems
with the XP Pro system if i remove the application "MusicMatch Jukebox"?
3 - i would like to update my Adobe reader but i noticed that the update
comes with "Yahoo Tool Bar". i don't want the toolbar, can i just remove it
when the adobe update is installed?
thanks for the help.
