Can anyone advise as to how to check if SP1 has been installed on my machine via windows update ? Ive had a look through the update history but can't see anything. I know that in XP it would normally tell you when you looked at the system information.
If you run WinVer it will tell you. On XP would go Start, Run and type in winver and click OK. Not sure where 'Run' is on Vista, but it should still support winver.
