All of a sudden, Internet explorer 11 doesn't work on my pc. It opens the browser window for a second or two and closes immediately. I've tried uninstalling and reinstalling, I did virus and malware scans, I run sfc /scannow and chkdsk commands, nothing worked. I tried opening Internet explorer without add-ons, and running as administrator, with no luck. What other ideas could I try? I do not know if it is relevant, but Chrome, which works ok, gives an update error (error 7).
