OK so I have this webcam and it keeps saying Windows XP home edition service pack 2 cd needed, and I don't have a service pack 2! What do I do I want to install my cam!

Service Pack 2 (English version) (http://www.microsoft.com/downloads/details.aspx?FamilyId=049C9DBE-3B8E-4F30-8245-9E368D3CDB5A&displaylang=en) is available on Microsoft's web site or through Windows Update. Download and install. Also highly recommend you do a full system backup before proceeding with installation in case the installation is problematic...
