The General tab in Control Panel's System program is a helpful, information-only window that displays:
The version of Windows installed on your computer (including Service Packs)
The Windows edition (Home, Professional, Media Center, and so on)
Registration information that was entered during Windows Setup
The type and speed of your computer's processor
The total physical memory (RAM) installed on your computer
You'll need some or all of this information when you request tech support over the phone, particularly if you're talking to Microsoft.
To display general system information:
Choose Start > Control Panel > Performance and Maintenance > System > General tab (or press Windows logo key+Break) (Figure 4.89 ).
