I have lost 'The multimedia class scheduler' from my computer, causing my audio on the computer not to work.

I can not find 'The Multimedia Class Scheduler' on my computer via the list of titles on 'Services' . It is as if it has been completely deleted and that i feel like i need to re install it somehow. Consequently my windows audio will not start under any circumstances, because from the research i have gathered it relies on the multimedia class scheduler to present for it to be able to be activated. The problem occurred after a windows 7 update. 

The symptoms of it show that there is a red cross over the speaker icon, it also says that one or more audio services is not running after the trouble shoot - hence missing The Multimedia Class Scheduler.

Any help would be great!

Thanks, Joe.

    1. Open a command Prompt by right clicking and select 'Run as Administrator'

    and then at the command prompt type:  chkdsk  /f  /r    then press the enter key.

    If prompted to schedule the volumn to be checked the next time the system restarts,

    enter: y

    Also if you know the manufacture of your hard drive you can download their diagnostic software.

    Another utility: SpeedFan has an online health analysis feature

    (SMART tab) for hard drives. It will show how your drives

    compares with other drives of the same make and model.

    1. Run the  SFC   /SCANNOW    command. This will check and repair if necessary any critical Windows system files.

    Click on Start/All programs/Accessories  then

    Right click on Command Prompt option and select 'Run as administrator'.

    (or "Safe Mode" open a Command prompt)

    At the command prompt enter:  SFC  /SCANNOW

    Not a hard drive issue. I reinstalled the Multimedia Class Scheduler  and it worked for several days. I have restarted several times during those days without issue. Today I have the same exact problem listed above again. The only thing that's happened overnight was Windows 10 updates and an update to NVidia. Reinstalling the service again but this appears to be a temporary fix until one of the programs mentioned does an update. Dell XPS 8500, Core i7, 12 Gb ram. Win 7 originally now Win 10. Any suggestions would be appreciated.

    I saw the typo and fixed it but still nothing came up.  When I go into registry edit the whole system profile is missing under multimedia.  Can't find it as of yet in process manager. Thanks though for trying.
