I have a Dell 1525 laptop and the other day I was updating it with Windows updates. My laptop didn't have SP1 yet so I installed that with some other updates and then my internet stopped working, even though it showed as connected. So I did a system restore to before the updates which fixed the internet. Then I installed all the updates except SP1 and the internet still worked. But when I tried to install SP1 (either in win update or with SP1 download) I get the error, "missing sqmapi.dll". This has happened to me before on a PC where I installed SP1 then did a system restore to uninstall it, then tried to install SP1 again, then got a similar error. So both times when uninstalling SP1 with system restore and trying to re-update SP1 has had the same consequences. So what is going on?
