I've been testing SoftPerfect ram disk these last few days. I'm not sure of how it does things internally, but I realize there is no windows service that gets installed to automatically mount the ram disk.
My question is, is the ram disk always on, even when theres no user logged on or such? As in a regular windows service?
It doesn't depend on the version. It depends on how you create the RAM disk.
In the main menu you can choose Disk - Add or Disk - Add Boot Disk. The former will create a RAM disk available when a user is logged on, the latter will create a RAM disk available immediately on the system startup.
