I purchased two identical PCs in March this year to use in two different
residences.
On one machine I cannot load update Windows XP manually or automatically.
The Update prog tells me which updates I need but when I click Express or
Custom the downloads fail.

When I check update history I have an error code 0x80200010.

I now have accumulated 26 failed security and critical updates since
purchase. The vendor of the machine does not know what the problem is. I
have tried turning off the firewall and the virus checker during the update
procedure.

Can anyone help?
