Media Center wont start on Vista - "Media Center has stopped working"


Active Member
I have just rebooted Vista and for some reason when I now try and start Media Center i get a message saying "Media Center has stopped working". When I click on view problem details it also tells me:

Stopped working

Problem signature:
Problem Event Name: CLR20r3
Problem Signature 01: ehshell.exe
Problem Signature 02: 6.0.6000.16386
Problem Signature 03: 4549b55e
Problem Signature 04: mscorlib
Problem Signature 05:
Problem Signature 06: 4536f11f
Problem Signature 07: 3318
Problem Signature 08: 15a
Problem Signature 09: System.UnauthorizedAccess
OS Version: 6.0.6000.
Locale ID: 2057

I have also noticed that there is a service called "Windows Media Center Service Launcher" which isnt started. When I try and restart it it just stops after a couple of seconds.

I have checked the media center event log and its full of messages like "The recording schedule has been corrupted and was automatically deleted on 08/31/2007 07:05:37. You may need to reschedule your recordings." I have done some searching and the only thing I have found that seems to relate to this message is this link:

I have tried some of the advice in this thred but the event log was then full of messages like "unable to find C:\Documents and Settings\All Users\Application Data\Microsoft\eHome\EPG\tracehelper\DefaultDomain-VISTAPC$.xml" so I restored the EPG folder and tried to just delete the massive .sdf files.

Does anyone have any ideas or know of a way to completely reset Vista Media Center back to default settings ?

Afraid not. You say a reboot started all this? What made you reboot? Were you installing/removing/tweaking something?

yes sorry forgot to mention :( I had just applied this weeks windows updates, all seem to be unrelated to MCE but to rule these out I have been down the route of uninstalling them but no luck.

I have seen a couple of utilities that seem to be able to "reset" media centre back to default but they dont seem to be supported on Vista:

I am convinced that there is some corrupt data (maybe guide data) at fault here and I just need to either delete a file or set some kind of flag for media centre to reinitalize its settings.

Any ideas ?

I've had strange things happen to me after updating vista.

Recently I updated vista and IE completely stopped working and kept crashing.
I did a system restore to just before I installed the updates, and after a reboot everything was fine again.


i would try turning off UAC in "user accounts" in the control panel..
good luck!


Hi folks;

I started getting this error after installing patch KB938979, ironically called a "reliability and compatibility" patch. I fixed it by navigating to folder "C:\ProgramData\Microsoft\eHome" and granting Full Control access the folder, its subfolders and files, to the Everyone security group. Hope this helps.....

A shame when it comes down to that, but with good backups, it shouldn't be too much hassle.
