today auto-update installed .NET framework 3.5 SP1 on my p4 3.06ghz computer. it boots up then freezes so i have 2 do a hard shutdown. i booted up into safemode then attempted 2 remove it but couldn't because of an error message in setup so did a sys restore and that removed all installed .NET frameworks so now none r installed and computer runs great. do i need the .NET frameworks? i understand the .NET frameworks r 4 programming which i don't do. now the auto-update icon is present but i'm afraid 2 install them. i searched the microsoft site then googled it but couldn't find a specific answer.
