#11
Only other thing i can think of at this point is corrupted files. Is Microsoft Edge working well or any other browser ? Have you done all windows updates and were they successful ?
If IE 11 is only one not to work you can try running system files checker. At an (Admin) Command Prompt copy and paste this and press enter, let it finish
sfc /scannow
Same open Command Prompt copy and paste this and press enter, let it finish
Dism /Online /Cleanup-Image /RestoreHealth
After reboot the PC, then try IE 11. Let me know if you receive any errors running these commands and if SFC finds corrupt files it fixed or can not fix.
