First of all, Hi everyone! I just searched for a W7 forum, since Technet's forum is not accessible at the moment. It seems to be a big community too. http://windows7forums.com/images/VB/smilies/razz.gif Hopefully someone out there, and answers my question: Environment: Both x64 OSs, Vista and Windows7 RC are installed on separate drives. A brand new (original MS laser 7000) keyboard and mouse is attached via wireless USB 2.0. All drivers are downloaded from Microsoft Hardware Support site and via OS integrated Windows updates. They work fine in both OSs.. However, when restarting from either one OS, on the Switchboard (Windows 7 as first and Vista as second choice) I'm unable to use the keyboard's up and down arrow keys. I see a transmission takes place (a green LED indicator flashes), but nothing happens on the screen. I then connected a second keyboard to the normal PS/port, and then used the up/down arrow, which then worked fine. After getting to the login page, the wireless keyboard worked just as it should. Also, while I had Vista with XP, the switching was effortless. Any Idea, how to solve this problem, to not have a 2nd keyboard attached just for that one down key click to get into Vista?
