As I said ,Recently I did a sfc/scannow scan and it had found some corrupted files. My computer sometimes working very slowly and freezes occurs. Later, I fixed them with SFCFix. But freezings still happens and computer is working very slowly. It is because of failure installation of language packs for ie11. I had tried to uninstall but failed. But interesting thing is that in-place upgrade to repair it is returning with compliance error.
