This link tells about that problem when Windows Update is searching for the version of windows update software that you have though, NOT the actual updates itself so I'm not sure if the this your problem or not.
On Sunday, Feb.20,2005, a friend reinstalled Win XP Home on my DELL Dimension 2350.
For some unexplained reason, Win Update's page states that it is searching for the latest Windows update...but then...nothing happens.
I have not been able to download SP2, either, for which I am concerned because my computer is unsafe and unsecure.
Please help me...I need it urgently!! Thanks!!
