Last year I wrote about how I was caught out with detecting Vista in login scripts (http://blog.sembee.co.uk/archive/2007/01/06/31.aspx).

Following the release of Service Pack 1 for Windows Vista, I was caught out again as the version number has changed. In my login scripts I use the output of the command "ver" to detect the operating system.

With Windows Vista RTM it was 6.0.6000. With Windows Vista SP1 it is 6.0.6001. Therefore any login scripts that detect Vista need to be updated to include both version types.

This is easily done and should not mean too much additional code.
If you have used the method in my examples and put the script commands in to sections, you simply need to add a line to the detect the later version:

findstr "6000" %systemdrive%\ver.txt
if not errorlevel 1 goto vista
findstr "6001" %systemdrive%\ver.txt
if not errorlevel 1 goto vista

:vista
rem vista commands here

By grouping them together the same commands can be used for both RTM and SP1 versions of Vista, unless you need to use different commands for the different versions.
