I’ve been given access to a server and told SP1 was installed on it, but I think maybe it wasn’t.
How can I check if Service Pack 1 is installed on Windows Server 2008 R2?
What I’ve tried:
If I right click Computer, then click Properties, it says “Windows Server 2008 R2” under Windows Edition. I would expect it to say “Windows Server 2008 R2 Service Pack 1” if it was installed, but I did find something in a Windows 7 forum about the Service Pack not showing up in computer properties.
If I click Control Panel – > Programs – > View Installed Updates, it’s not there either. I don’t see the words “Service Pack” or any reference to KB 976932, which I believe is the KB for Service Pack 1 for Server 2008 R2 as well as Windows 7. (Maybe I’m wrong?)
If I run msinfo32, it shows Version as 6.1.7600 Build 7600
If I call ver.exe from command prompt it says Microsoft Windows [Version 6.1.7600]
Is there any other way to verify if SP1 is installed? Or, could I prove it is NOT installed?
UPDATE: Maybe someone can move this to Server Fault?
Here’s the explanation I received: “The Windows Server 2008 R2 w/sp1 is from our Microsoft download, and the key used only works on that download” Is this normal/expected behavior for a MSDN download?
Go to start > run and type winver. Hit enter and a dialog will appear. On the second line in the main dialog body, you will either see something like this:
Microsoft Windows [Version 6.1.7600]
Or, if SP1 is installed you will see this:
Microsoft Windows [Version 6.1.7600: Service Pack 1]
If a service pack is properly installed, it will always appear in the winver dialog, so it’s absence is proof that it is not installed, or is corrupted in some way.
