I know this sounds stupid, but I'm new to this and I need you guys to confirm something for me...
I'm currently using Windows XP SP1, and I didn't use a 'real' Windows CD.
1) Upgrading from SP1 to SP3 doesn't erase any of my files/programs on the computer, right?
2) I'm thinking of downloading the install file from here :http://www.microsoft.com/downloads/details.aspx?FamilyID=5b33b5a8-5e76-401f-be08-1e1555d4f3d4&DisplayLang=en
Will it be a problem that I didn't use a 'real' Windows CD to install Windows in the first place?
Thank you very much!
