How to Reset Your Zune
Here we take a look at the original Zune, without a touchscreen. Microsoft has always taken the heat when it comes to their software crashing, rebooting of its own free will or otherwise malfunctioning. Of course, it's no different on the Zune, and your media player may stop working once in a while. Don't fret. Just follow these simple steps to reset the Zune:
1. First, try switching the hold switch on and off. The switch can get stuck now and then, even when you think it's off. So don't proceed until you give this a try.
2. So the hold switch flicking hasn't helped? Try plugging the Zune into your PC using the sync cable. That does work to unfreeze your Zune once in a while.
3. Still stumped? Hold the "Back" and "Up" buttons together until the screen turns black. It should happen within 5 seconds. This combination will work even if the hold switch is on, so try step 1 first.
4. The Zune logo will now appear along with a white progress bar in the middle. Wait a few more seconds and it will be back to normal.
5. An alternative, if the problems keep recurring, is to click "Install Games" in the Zune software even if the games are already installed. It will reinstall them anyway and reboot when finished.
The above steps can have some side effects, which however unlikely, are still possible. Recent changes to settings such as new radio presets, background picture, etc. may be lost.
