Changing build string

I'm currently modding a Sp4 build of Windows 2000 & was hoping to

change the build string as shown on the desktop.

Is there anyone here who knows what file/s are responsible

for showing the build string on both the desktop & system properties.

I'm using tweakUI for showing the build on the desktop & found

that win32k.sys changed the windows name, but not the build string.

I attempted to use the search feature but all links appear to be

dead, I get a message of having to report the dead links..

I'll post a screenshot if you want to know what the project is about..

Thanks in advance..
