Similar Issue
I got the same error regarding "ServicePackFiles/i386/conrtols.man" being replaced by an unrecognized version... it occured when I was running Windows Update with the XP Update KB900725.
My comp was having major issues. I did a lot to try to fix it. No luck. I eventually uninstalled SP2, reinstalled Windows XP, and deleted a ton of old/unnecessary data and problems.
When I first ran Windows Update I got this error message. It seems to have had little affect on the computer - I think, it hasn't been long enough to tell, really.
I'm just confused as to what this could mean??? Could it be an issue???
And I'm guessing the work I was doing counts as "Major HD activity"
