Hi,
Welcome to Microsoft answers.
I suggest you to perform system file checker, it scans system files and replaces incorrect versions of the system files by using the correct versions.
Here are the steps:
- Click Start, click All Programs, click Accessories, right-click Command Prompt, and select Run as Administrator.
- Click Continue or supply Administrator credentials if prompted.
- In the Command Prompt window type the following, and press Enter:
sfc /scannow
Here is an article that will give you information on SFC Scan:

Follow these steps and check if it works fine.
- Close Microsoft Media Player for at least 30 seconds
- Click Start and then Run
- Type the following into the textbox:
[list]%userprofile%\Local Settings\Application Data\Microsoft\Media Player
- Click OK and a folder showing you your library files will appear
- Erase all the files that end with .wmdb
- Open Microsoft Media Player
- Push F3
- Select the locations for your music files
- WMP will reindex your music
