I live in the Linux world, so this might be a stupid question to Windows users.
I need to set an environmental variable. I know I can do this through the control panel, but what a pain in the ass.
If I open a command prompt and use the "set" command, the variable seems to last only as long as the commend prompt session is open.
How do I set an environmental variable from the command prompt so that it lives beyond the command prompt session?
And while I'm at it, can someone recommend a book that explains how the Windows OS works? I'm not looking for a "Windows for Dummies" presentation, but one that goes a little deeper ... something akin to "Linux in a Nutshell".
