I have since my previous post installed the _manually_ downloaded file for
KB91945 and restarted. The restart failed on boot up, hanging with no
activity, so I forced a shut down and started again. All seems fine now as
far as browsing, accessing SystemRestore, etc.
At the WindowsUpdate site, it no longer offers the file under
OptionalSoftware updates, yet the History section shows it as having
installed on Apr 4, as before, though I know it was unsuccessful until just
now, Apr 8th.
At least it didn't mess things up again!

Off to ride the mountains, D H
Frank, Thank you for helping folks out here! I've not needed to check newsgroups for a long while, mostly after getting a new machine with XP on it and having VERY few problems anymore, but this one hit me so hard it ALMOST stopped me dead in my tracks. I was about to totally format and reinstall because I couldn't figure out ANY way of fixing the troubles I was having. No internet access because IE wouldn't load anything but white page. No ability to "repair" IE anymore; was not allowed to reinstall windowsXP home because "your version is newer." (Of course it is, it's been updated beaucoup times!) Anyway, I really believe your advice to the OP is going to be repeated a LOT, based on what I saw on this group when I just came back to check it out. Seems like a lot of folks are getting hit by something that causes similar issues. I'll copy below what I responded to one earlier post, since it adds a bit more that may or may not be necessary to fix the problem, but might help if it IS needed.
I hope this helps: I had problem of blank
screen on EVERY IE window, all my windows Help & Support attempts, etc. I
finally was able to search via an old computer just before giving up all
hope of fixing this short of total format & reinstall of my otherwise
healthy laptop. Then I found article KB902932 online (search for this and
save the file; you may need it again!)
I tried the first section of fixes (re-registering 8 DLLs via the Start/Run
command) and it totally fixed my problems. I now am quite sure the problem
came as a result of the Optional software "Update for WindowsXP KB912945,"
done on my laptop on April 4th. The WindowsUpdate _History page_ shows it as
"installed succesfully," but it still shows as "downloaded; ready to
install" on the list of Optional Software Updates when I go to WindowsUpdate
now.
I did some checking and read the log file generated on my computer about the
KB912945 update (which apparently did install?), and noticed a correlation
between files it copied and the DLLs that had to be re-registered on my
machine to repair the blank screen and other problems. The following files
are involved with both the above mentioned KB articles:
urlmon.dll
shdocvw.dll
mshtml.dll
browseui.dll
In addition to these, 4 others have to be fixed, but I don't see them on the
log of the suspect update file. Maybe I'm grasping at straws, but the timing
of the failure and the fact that the History at WinUpdate saying it
installed successfully doesn't make sense when it still comes up as an
update to choose in the Optional Software section at the site, nor does it
make sense that it says it's already downloaded; ready to install.
I probably am going to gamble and download the full file separately from the
KB article page and try to install it manually from the Run command line. If
it screws things up again, I'll be back to fixing the DLLs again, but
hopefully it will work. I hope it was just a corrupted file that somehow
still tried to install itself.
I do hope this fixes your problems as well as it did mine. I think there are
probably going to be a lot of folks in our situation if MS doesn't catch
this quickly and correct what is going wrong, either with the download of
the fix or else in it's installation procedures, I don't know which.
Good luck to you (and all of us!)
