Find the GP Version and Service Pack

I literally spent 30 minutes trying to find the GP service pack that was installed on my server.  Why can’t this freaking easy stuff be standard?

If you click on help (upper right corner)  as illustrated below:

You will get the GP version but no information whatsoever about the Service Pack.

So my next step was a Google search, which led me to the following websites below.

GP Version 10
No Service Pack: 10.00.0774
Service Pack 1 : 10.00.0903
Service Pack 2 : 10.00.1061
Service pack 3: 10.00.1193
Service Pack 4: 10.00.1424, 10.00.1411
