VWS isn't supplied with VMS -- DECwindows is.  But you can have them both on the
same workstation.  Here's how, roughly:

    --	Install VMS and DECwindows.  Tune the system according to the
	documented recommendations, and save a copy of SYS$SYSTEM:VAXVMSSYS.PAR
	in SYS$SYSTEM:VAXVMSSYS.DECWINDOWS.
    --	Install VWS.  Tune the system etc., and save a copy of
	SYS$SYSTEM:VAXVMSSYS.PAR in SYS$SYSTEM:VAXVMSSYS.VWS.
    --	The most crucial SYSGEN parameter is WINDOW_SYSTEM, whose value (use
	HELP in SYSGEN) is

		0	No window system
		1	DECwindows
		2	VWS

To change window systems, copy or rename the appropriate parameter file to be
SYS$SYSTEM:VAXVMSSYS.PAR, and reboot.
