This happens when you are chatting and on a web page. It's normal to press enter when you play a game
There are many ways to open task management: the fastest way to do this: press CTRL+shift+esc to open the Windows Task Manager window. After you find the process, end it or open it and turn it off.
Solution: call up the task manager (taskmgr (or taskm.exe) and jump out of the Windows Task Manager, and find the windows mobile center in the process tab".
In the win7 system, press the Enter key to eject the power options (control panel all control panel items power options edit settings).
I just have this problem, you are actually accidentally opened windows mobile center, just in the power options position, so press enter on the power options, you use the task manager to see if it is to open the windows mobile center, off just fine
