I have removed SP1 from my PC. Now, I'm able to get online and surf. The .NET update wasn't an issue, even though it was done soon after the SP1 install. It did that on its own(auto) update and then it seemed the problem surfaced which is why I question it. Odd, removing SP1 seems so much faster than the install. Now, you would think the auto update would see that SP1 needs to be re-installed, yet no prompting. The update service shows no updating required, yet SP1 is removed??? It just doesn't make sense. maybe MS removed it as a precaution to some forthcoming SP1 fix. Yet, SP1 been out for awhile. Yet, my PC has only been clamoring for the week or so(I think) for it.
I did everyone else's Sp1 updates with no issues. Now, I do mine and it refuses to work when online.
