Clean Batch File - Deploying Service Pack 1 for Win7x64Pro

I've got a basic computer startup script to deploy Windows 7 SP1:

\\svr\share$\win7sp1\windows6.1-kb976932-x64.exe /quiet /nodialog /forcerestart

I want to add something ahead of this line to have the script check whether SP1 is already installed, and if it is, to terminate the script entirely.  Can this still be done w/ batch or does it have to be done with VBS?  What's the syntax?

There's a few ways it can be done, mostly all dealing with server pack or build numbers.

Here's my stab at it using a one-line script, but it's a pretty hefty one-liner.  I went with a REG QUERY comparing the "CurrentBuildNumber" value since Microsoft actually started incrementing that when service packs are added since Microsoft Vista.  Windows 7 is "7600" and Windows 7 SP1 is "7601".

For /f "tokens=3 delims= " %%A In ('REG QUERY "HKLM\Software\Microsoft\Windows NT\CurrentVersion" /V CurrentBuildNumber ^|Find "CurrentBuildNumber"') Do (If %%A LSS 7601 \\svr\share$\win7sp1\windows6.1-kb976932-x64.exe /quiet /nodialog /forcerestart)

Let me know if you need something additional such as OS type detection (WinVista, Win7, etc) as well

I can't speak for batch scripting really, but WMI knows. And you can get CMD to tell you it with:

WMIC OS GET CSDVersion

If the output from that can be tested...
