Hi, I have windows 7, IE10. When trying update to ie11 I got an error something with c947, so I tried to go to the basics and remove IE completely (control panel->uninstal programs-> uninstall updates->unistall windows internet explorer 10) and got an error (without a specific number). Quick googling led me to make an sfc/ scannow which informed me I have corrupt files but it can't fix them. I then tried to remove these KB: ww sevenforums com/performance-maintenance/300474-how-do-you-fix-corrupted-files-found-sfc-scannow-4.html Didn't help. I then tried to safe mode and to Dism /Online /Cleanup-Image /RestoreHealth bot to no avail (error 87 not recognized command in this context). Not sure what's next and would appreciate help. thank you very much.
