A. As with user variables, these can be changed using the system control panel applet:
- Start the System control panel applet
- Select the Environment tab
- Under "System Variables" select a variable and its value will be displayed. Modify it in the Value box and click Set.
- Once you have made all changes click Apply then OK
Alternatively you can directly edit the registry to make these changes
- Start the registry editor
- Move to HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\Session Manager\Environment
- Double click on the variable, e.g. Path and edit the value. Once complete click OK
- Close the registry editor
A final method from the command line is to use the SET command
C:\> set OS=OS2 DON'T do this :-)
