>The close is necessary if you want to free up the resources right away. Without it, the process' resources are retained until the garbage collector kicks in. The close will force them to be released immediately.

Thanks for the info

>Even better than using the close though would be to put the process in a using block (http://msdn.microsoft.com/en-us/library/htd05whh%28VS.80%29.aspx). That will ensure that its resources are released even if there is an error that prevents it from reaching the close and will handle the close for you.

Good one, I am using it in the Data class but didn't think of using it in the Process class, which is greatly welcome because this one processes DOS utility and other types of programs so this will be safer.
