You can also check and see if there is an option to uninstall it through the control panel.
What did you do prior to installing SP2 to assure your computer was ready? Did you go to your computer company's web site and read any recommendations? Did you make sure your computer is virus and spyware free?
Tried to install Win.XP SP2 last night from CD-ROM. Got a message to say 'setup cannot copy the file ipnat.sys and that continuing installation would mean windows might not work properly. I tried to stop the installation, but it wouldn't let me do that either. So I think I have only part of it installed. But now my new flash drive which was working perfectly, isn't working at all.......I am getting a message that says insert disk in drive g.........I'm at a loss to know what to do to get it working - i'm assuming this is a result of the Win SP2 part installation..........????
Help!!!!!
Thanks
