WinLock ensures that only authorized people can access sensitive information on your computer, as well as designate time limits for use.
This security tool will allow you to restrict your users from accessing essential system resources like Control Panel, Desktop, and system registry, disable Windows hotkeys (such as Alt-Ctrl-Del, Alt-Tab, Ctrl-Esc, etc.), hide the Start button and taskbar. And it runs from the system tray and requires a password to access any of the available settings.
WinLock loads automatically with Windows and allows you to add an optional startup message, provide audio notification, and set the time limit. Once reaching that limit, Windows is summarily shut down. You can toggle the timer on and off from the tray. It also lets you deny access to selected files, applications, Explorer windows (Recycle Bin, My Computer, etc.), USB and hard drives, filter Internet content, and prohibit access to questionable Websites. When enabled, there is no way around it without the proper password.
