I have found this MIcrosoft site very useful.
Just the command line reference alone is a wealth of information.
The site has guidance from Windows7 to XP.

Thanks for the useful tip. Strange that nobody else responded, since use of the command line is sometimes unavoidable. And because it's rarely used, one tends to forget the numerous commands.

Thanks
I think the lack of response maybe because I posted it in the wrong place. I have only just joined this forum. On the other two sites I work on Tech Support Guy and Geeks there are special forums to place something like this and then an admin decides whether or not to make it a sticky, I could not find it on here.
