I have fives pages of Windows hotfixes (if I print screen and post into Word). Most of these hotfixes took place during 2008 and a few in 2007. There must be about 130 of them. Is it necessary to keep them all? Correction - not all of them are hotfixes; a lot are security updates for Windows XP and updates for Windows XP. There are about 10 hotfixes - Sorry! I will delete the hotfixes but leave the rest unless informed otherwise. I am also confused because if you see attached list of programmes it states Service Pack 3 but I ran the quick version of Malwarebytes just now as I got a virus or something on the Internet (there was nothing in my computer) and the log said Service Pack 2 at the top.
