Running tar for Windows, using this command:
c:\Program Files\GnuWin32\bin\tar.exe -xzvf filename.tar.gz
gives the following error
c:\Program Files\GnuWin32\bin\tar.exe: Cannot fork: Function not implemented
c:\Program Files\GnuWin32\bin\tar.exe: Error is not recoverable: exiting now
On windows it doesn't seem to call gzip automatically.
Therefore:
You need to install GZIP for Windows
And then run a command similar to what follows:
"c:\Program Files\GnuWin32\bin\gzip.exe" -d -c "filename.tar.gz" | "c:\Program Files\GnuWin32\bin\tar.exe" -x
Another choice James is 7-Zip. It's open-source also but has an easy to use interface.

Doh,
I forget that Windows has utilities. I tend to look around for the ported linux stuff because I'm familiar with it.
