My computer is now running on Windows XP SP3 and I recently uninstalled the
IE 8.

Now, I could not reinstall the IE7 as they prompt me an error saying I
already have the latest version of Internet Explorer.

I tried a system restore to the date I still has the IE8, but the current
IE8 is missing a lot of features/interface, such as the "File; Edit;View;
History; Bookmark; Help" toolbar.

After reading the relevant downgrading steps in Microsoft website, I learnt
that I must uninstall SP3 before uninstalling the IE8.

I would like to try this, but I was wondering after I uninstall SP3, there
will be no Service Pack in my system/computer.

I could not do an Automatic Update as that section in Control Panel is
unclick-able (in grey). However, my computer will do the updates while my
computer is shutting down. Thus the other alternative to get the Windows
Updates is by going to Microsoft website and download them using Internet
Explorer; which is one of the reasons why I need to restore IE so much.

and I just reformatted my computer in school on last Monday, as I do not
have a Window XP installation disc .

Therefore, how do I obtain a Service Pack after I uninstall SP3? Also, what
will be the result after the un-installation.

I would greatly appreciate if someone can advise me on this problem.

Thank you.
