I've never actually used the Fax service in windows, but in just looking at it, there is a personal conver pages option in the Fax Console.
To get to the Fax console goto Start -> Accessories -> Communications -> Fax -> Fax Console
Then in the console, click tools -> personal cover pages
You can then select new to design your own, or import them using the .cov or .cpe file format.
Its a frigging Laptop, not a Labtop!!!!
