Dism.exe /online /Cleanup-Image /StartComponentCleanup&sfc/scannow&Dism /Online /Cleanup-Image /RestoreHealth&sfc/scannow&pause
And let it run through then reboot and run it again to check if it cleaned everything. It can take a while depending on if you have HDD or an SSD. It might appear to freeze, just let it run, sometimes it jumps from 20% to 100%, so just be patient.
After second reboot try out pinning again.
