Symless Synergy is a powerful software solution designed to enhance productivity by allowing seamless sharing of mouse and keyboard across multiple computers, regardless of their operating systems.

Synergy for PC lets you easily share a single mouse and keyboard between multiple computers with different operating systems each with its own display without special hardware.
