Windows Media Player not working.

If SFC could not fix something, then run the command again to see if it may be able to the next time. Sometimes it may take running the sfc /scannow command 3 times restarting the PC after each time to completely fix everything that it's able to.

If not, then run the Dism /Online /Cleanup-Image /RestoreHealth command to repair any component store corruption,

Repair-WindowsImage -Online -CheckHealth

Repair-WindowsImage -Online -ScanHealth

Repair-WindowsImage -Online -RestoreHealth

Restart the PC afterwards, and try the sfc /scannow command again.

If still not, then try using OPTION ONE above to run the sfc /scannow command at boot

If still not, then you could do a refresh of Windows 8, or run a System Restore using a restore point dated before the bad file occured to fix it. You may need to repeat doing a System Restore until you find a older restore point that may work.

If still not, then you can use the steps in the TIP box in the OPTION THREE section to manually replace the files that SFC could not fix.

Refreshing your PC goes like this:

• The PC boots into Windows RE (Recovery Environment).
• Windows RE scans the hard drive for your data, settings, and apps, and puts them aside (on the same drive).
• Windows RE installs a fresh copy of Windows.
• Windows RE restores the data, settings, and apps it has set aside into the newly installed copy of Windows.
• The PC restarts into the newly installed copy of Windows.

"When you reset your PC, the drive will be completely reset, and all your apps and files will be removed from it. Windows 8 will be reinstalled, and you'll need to change any settings and reinstall any apps that you want to get back after resetting. If you know if any files that you don't want to lose, then you should back those files up before starting the reset"
