I do not understand the terminology "elevated command prompt option 2".
If you open (click on) the
SFC /SCANNOW Command - System File Checker link you'll see three options pertaining to the System File Checker scan. Option Two explains to how run the scan from an elevated command prompt.
From what you've described (getting an error when trying to run system restore, and having issues with the media player) I still think you may have damaged system files. Running check disk tries to correct any errors physically associated with the hard drive. It doesn't necessarily correct errors associated with programs or software that are on the hard drive. Running a System File Checker scan would hopefully repair your media player.
* From your desktop, click the start button. You should see a blinking cursor in the bottom box called "Search programs and files"
* Type in the letters
cmd and your start menu should change to a single option at the top called cmd.exe
*
Right-click on cmd.exe and a sub-menu should open with the option to
Run as administrator (this is also known as opening an elevated command prompt)
* Click on
Run as administrator and you'll get a prompt asking if you want this program to make changes to your computer. Click yes
* A new window will open with a black background and white letters. You will see
C:\WINDOWS\system32>_
with a blinking cursor. Simply type in sfc /scannow and click Enter.
(Please note there is a space between
sfc and
/scannow.) The system file checker scan will start to run and examine all protected system files. It will also try to replace incorrect, corrupted, changed/modified, or damaged versions with the correct versions if possible. The Windows Media Player files are among the files that will be examined. The scan can take a long time to run. When it finishes you may get a notice that some files couldn't be repaired. Try running the scan two more times (total of 3 scans.)
