Windows Media Center opens up by itself sometimes. How can I stop this from happening? I don't even use this program at all.

It just comes up full screen with no apparent trigger. No keyboard shortcuts that I know of.

At machine startup? After opening a file of some type? Keyboard have a default key which will open your default media player? Unfortunately everything happens for a reason...we just need to figure that reason out... –  Aaron McIver Jan 12 '11 at 20:22
    
Not after machine startup. Not after certain file type. I was just typing along in my code editor and it came up. I can't imagine any keyboard shortcut I could have pressed but I know it is possible. @Aaron –  George Bailey Jan 12 '11 at 20:39

There are a couple of things I've seen cause this:

Multimedia keys on the keyboard - if your keyboard has multimedia keys, some of them may launch MCE. With some keyboards it is easy to hit these by accident.

Remote control receiver - I have an MCE remote control receiver attached to my PC. Pressing certain buttons on my universal remote (the ones you would expect, but also others like the "Info" button) causes MCE to open up. Some laptops have receivers built in, so this might apply to you even if you don't think it should.

Check for command line parameters to ehshell.exe. Not sure if any are passed to MCE but might give you a clue. Since you're running Windows Vista, you can see the command line right in the Task Manager. View menu -> Select columns -> check "Command Line."

It is not a multimedia key. It just happened today. I selected text, pressed Ctrl+Space, Ctrl+Enter and Enter in NetBeans editor which was running a bit slow at the time. (Also I seriously doubt it is a NetBeans problem.. It just happens that is the tool I am using most of the time.) and then my laptop screen (secondary monitor) went blank and then the Media Center started. I do not have a built in receiver or a remote. How do I get to Process Explorer? –  George Bailey Jan 18 '11 at 20:10
    
Process Explorer is a Microsoft utility. Added a link to the Process Explorer download page. If you're running Windows 7 (not sure about Vista), you can see the command line right in the Task Manager. View menu -> Select columns -> check "Command Line." Also, since you are running NetBeans most of the time, it is not unreasonable to suspect it might be related. See if you can make it happen without NetBeans running, to narrow down the issue. –  skypecakes Jan 18 '11 at 22:14

I have it too sometimes. In the three years I have Windows 7, it happened to me maybe 4 times.

I don't have a remote control or media keys.

At first, I thought it might be some weird shortcut I accidentally pressed, but this last time this couldn't have been the case. I was watching a video in mplayer classic (which I've been doing every day for the past few years), went to the toilet, came back and pressed space (the play/pause key). After a few seconds, media center popped up full screen, made noises, all while my video was playing. It even changed my screen resolution to something higher than it used to be.

I tried the trick for turning off windows features, but I won't know if it's effective until I reboot, which might be months from now.

For future research, These processes were found, with these parameters:

1 "C:\Windows\eHome\EhTray.exe" /nav:-2

2 "C:\Windows\eHome\EHShell.exe" /homepage:Home.xml /prefetch:0

3 "C:\Program Files (x86)\Windows Media Player\wmplayer.exe" /SkipFUE /RemoteOCXLaunch /SuppressDialogs

3 was a child process of 2.

The following information was found here.

Have you gone to Programs and Features and uninstalled and reinstalled Windows Media Player?

Uninstalling and Reinstalling the Windows Media Player:

Step 1. Uninstalling the Windows Media Player:

  1. Go to Start and in the search type "Turn Windows features On or Off".

  2. Click on "Turn Windows features On or Off".

  3. Browse to the Media Features and uncheck the mark in front of Windows Media Player.

  4. Restart the computer

Step 2. Reinstalling the Windows Media Player:

  1. Go to Start and in the search type "Turn Windows features On or Off".

  2. Click on "Turn Windows features On or Off".

  3. Browse to the Media Features and place a check mark in front of Windows Media Player.

  4. Restart the Computer.

If you are having trouble using Windows Media Player, try using the troubleshooter to see if that fixes the problem.

Open the Windows Media Player Settings troubleshooter by clicking theStart button, and then clicking Control Panel. In the search box, typetroubleshooter, and then click Troubleshooting. ClickView all, and then click Windows Media Player Settings.

Also, people in the forum posted that they were using the Razer Lacosa keyboard. If you are also using this, it may be an issue with the keyboard. I would just uninstall Windows Media Player if you don't use it, just to save time.

-Good Luck!

I have the same problem, it seems to be connected to a keyboard shortcut for me, but I cant figure out which one—whatever it is I hit it about once a month when coding in visual studio/resharper. It always seems to happen in and around Ctrl/Shift/Alt/Windows key or some combination of these and possibly the space bar or some character around s on the keyboard.

Having real trouble figuring out what shortcut it is—because it takes a while to load I often dont know exactly when I've triggered it. Didnt even know what the program was to start with—I've never used Windows Media center in my life—thought it was a 'Get Started' screen for Windows Media Player or something. Think everytime its happened I've had WMP open.

Im using windows 7. Found this article which looked promising; however I checked the shortcut and found it was set to none, so I'm a bit stumped.

I solved this problem by uninstalling media center by going: Control Panel=> Programs and Features => Turn Windows Features on or Off (left hand panel). Not an ideal fix maybe but ok if you never use the program.
