Make sure your PC is setup to automatically receive updates from Microsoft / Windows
Update.
(you especially need to check this if you've done the reset procedure above,
as it can wipe-out the update settings)
Go to: http://update.microsoft.com
and make sure it works - it may give you a warning (yellow bar) at the top of the
browser window asking if you want to allow the ActiveX control run. Make sure you
pick the one that says something like "always allow" or whatever it is
(I don't remenber the exact verbage).
Once it downloads & runs the control, there is a button near the top-right of
the page that says something like: "Pick a time to download updates" -
Choose the option to automatically download & install at 3:00am every day. Of
course, the PC will need to be powered on for this to take place.
If your not already running the version that's named "Microsoft Update",
it will probably offer that option on the page as well. You should be using the
Microsoft Update version, so install it - it extends and takes the place of Windows
Update. You'll probaly be presented with the ActiveX warning again - allow it.
Next, after making sure it's setup - you probably need to run it manually by
going to the same page and clicking on the Express update button. It might take
a few minutes to find all of the updates. then you'll click on something like
"View and Install Updates" - this will show you the list of updates it
wants to install. Then you simply click the install button and let it do it's
thing. This could take quite a while if it hasn't been updated recently - so
be prepared to wait before running it.
Sometimes it'll tell you to restart the PC to finish installing the updates.
Once it restarts, run the express update again until no further updates are available.
This can get quite annoying after a few restarts or updates, but it needs to be
done if you intend for your PC to be protected from possible security risks.
Once that is done - then you can run it in "Custom" mode to find other
optional updates that may be available for certain software on your PC, and to install
new optional programs Microsoft - things like Live Messenger and such. You'll
be able to pick and choose the updates you want when in custom mode.
