Environment

The key HKCU\Environment defines per-user environment variables. Normally, all you see in this key are two values: TEMP and TMP. Both are REG_EXPAND_SZ values. You can add environment variables to Environment, however, and then use those from within batch files, REG_EXPAND_SZ values, and so on. Of course, you can also rely on the user interface to add environment variables. In Control Panel launch System, and then, on the Advanced tab, click Environment Variables. Per-user environment variables are at the top of the dialog box, and per-computer environment variables are at the bottom.
