After setting up a Windows 2008 x64 server (not R2), I installed a number of Microsoft updates. After installing these updates, the computer reports that it has SP1 installed, not SP2.
I believe the culprit is KB917607, which allows Windows 2008 to display .hlp files.
Now I have to upgrade Internet Explorer on this server, and it won't install without SP2. I am very leery about reinstalling SP2, as I have installed a large number of post-SP2 updates, and I've had issues after reinstalling SP2 in similar circumstances.
How can I fix Windows so it reports the correct service pack?
UPDATE: One more piece of information - if I go into the control panel app "Programs and Features" and click "Show Updates", update KB948465 is there. That's SP2, but computer properties still show SP1.
