Hey. My updater just prompted me for this update about 3 hours ago. When i rebooted after the install my computer basically started to take a huge s**t. Everything slowed to a molasses-like state and I couldn't connect to the net. Things quickly came to an eventual freeze. I did a system restore and now everything's back to normal... I didn't know if it was something malicious or not posing as a SP upgrade so I checked the windows site and it was in fact available for download. Anyone who knows why this may have occurred? I may need to eventually upgrade in the future.
