"SysProtect is a freeware utility that resides in the Windows 95/98 system tray along the bottom right of your screen. It gives you the ability to lock down your Windows 9x workstation just as you could with Windows NT. Additional features include ability to display your screensaver after it has password-protected your machine for you, along with allowing you to specify a time interval for automatically protecting your system after a given amount of idle time.
"With this latest version, you can now use your own favorite images as your screen wallpapers while your machine is locked down, as well as receive log reports on any failed login attempts while you were away!"
