I have the Microsoft Wireless Natural Multimedia Keyboard, along with the mouse that came with it. I love it WHEN it works. But each time I restart my computer, it is a coin toss whether or not my pc will find the keyboard and think it is installed. Sometimes uninstalling/reinstalling the software works....sometimes restarting the pc 1-10 times works...sometimes pushing the button on the reciever and keyboard works...sometimes nothing works until the next day. I'll never buy another cordless.:thumbsdown:
