The OutKafe Client for Windows is maintained by Philip J. Hess. It was based on the Linux Client but ported to the windows platform.
This allows you to run an OutKafe powered cybercafe using windows desktops and a Linux server.
OKWin works by locking out access to the desktop and disabling functionality until a user logs in. Once a user logs in, the system is restored to normality until such time as the user logs out again or runs out of time.
OKWin was first released for OutKafe 5.1.0 and this is the current version.
