Windows Media Player - Rebuild Corrupted Libraries

How to Rebuild Windows Media Player Corrupted Libraries

   Information
This tutorial will show you how to rebuild your Windows Media Player (WMP) libraries in order to remove corrupted files (for example, files deleted from the hard disk that linger in the WMP library) in just a few, easy steps. This tutorial can also be applied to other issues.
   Note

  • Using this tutorial will not delete any media files physically; instead, it will reset the WMP libraries to their default state, without changing your previously made settings.
  • Windows Libraries are not affected by this tutorial.


The N and KN editions of Windows 7 have all the features that normally come with each individual Windows 7 edition, except for Windows Media Player 12 and related programs, such as Windows Media Center or Windows DVD Maker.

The N editions of Windows 7 allow you to choose your own media player and software required to manage and play CDs, DVDs, and other digital media files. If you choose to use Windows Media Player 12, downloading it, along with related software, is free. Download Media Feature Pack for Windows 7 N with Service Pack 1 and Windows 7 KN with Service Pack 1 (KB968211) from Official Microsoft Download Center
   Tip
Please make sure Windows Media Player is closed during this process.





Here's how:

1. Click on the Start Orb and type "services" into the search, then select Services from the list of search results.

Alternatively, you can right-click the Computer icon, select Manage, then choose Services under "Services and Applications" in Computer Management.

2. In the list of services, locate "Windows Media Player Network Sharing Service" and stop it via one of the highlighted options.

   Tip
Please keep the Services window open, you will need it later.


3. Click on the Start Orb and use the search again, this time type in C:\Users\(user)\AppData\Local and click the Local folder from the list of search results.

4. Inside the "Local" folder, navigate to the "Microsoft", then "Media Player" folder. Delete all the files contained in this folder and close the Explorer window.

5. Now go back to the Services window and start the Windows Media Player Network Sharing Service. Next time you start Windows Media Player, it will automatically rebuild all libraries using the information on folders that are included in the Windows Libraries.

Thanks Gornot

Thanks for the great description of how to do this. I had to do this before but forgot about it when my media player started acting strange again. Media sharing wasn't working properly and cleaning out the Media Player folder seems to have immediately fixed the problem. This also works for Vista systems which is where I had to do it before.

when i turn the player on i always have to wait for to load up the files, then it'll repeat many of them,and it will label them (wma and m4a) so should i use this method also, or do i have to do something else

I think it suffices if you delete the .wmdb folders only.

I got thru step 2 and got a Services Error Message: Windows could not stop the WMP Network Sharing Service on Local Computer. This service did not return an error. This could b an internal Windows error or an internal service error.

The problem I'm having is that WMP 11 occasionally duplicates files in random folders and for some reason has done so recently with many of them...to many to change manually. What gives here?

Strange, have you checked the options on the wmp? Scanned for viruses and others threats?

Don't what options those would be. Know viruses. I guess it's time to get a new player. I'm sick of dealing with it. I've been putting up with glitches and problems for 12 years. If MS doesn't care about WMP, why should I?

Then if you decided that, get VLC.

Windows media player corrupted

Thanks for this information. I got to this part where I typed in "C:\Users\(user)\AppData\Local" but "Local" doesn't open to any option for Microsoft media???????? When I clicked on "Local", it opened to "temp" files???????? Not sure what I'm doing wrong? Thanks for any help you can provide at this point.

EFE

PS:
My problem is WMP has a corruption that won't erase the files completely, after I deleted all the music files so I could start over with a clean library, all my music icons still show in the library although none will play, the music is gone but not the icons and lists of songs?

New Acer laptop with Windows 7 and Intel processor.

Still hoping someone can answer my problem? I'm stuck at stage 3 of the repair, it doesn't open to a "Local" file that will allow me to delete WM library files. My "Local" opens up to "temp" files???????? Stuck and bewildered. :(

You should replace (user) with the actual username in Windows. e.g.

C:\Users\oreo27\AppData\Local

Let me know if this works out for you :)

Thanks oreo27,

Tried that (my name in place of user) and it gave me a list again but not with "Microsoft" and WMP files that could be deleted? The only "Local" icon opens up to temp files. There are list of 3 Microsoft files, one is Microsoft Feed, Microsoft a 8be and Microsoft a 823, none of them give me WM files??????????? Confounded! ))) ;
