If you’ve ever searched for things like
- Internet Explorer automatically opens and closes
- How to repair or reinstall Internet Explorer
- IE opens, flashes then closes immediately
then you know how frustrating it can be to have Windows automatic updates install the latest version of MSIE only to have it not work the next day;
I had this happen to me today and I spent nearly 90 minutes searching for solutions, trying various things solutions and repairing my Windows install.
- Resetting MSIE to its default settings via Control Panel http://support.microsoft.com/kb/967896
- MSFixIt to do the same http://support.microsoft.com/mats/ie_freezes_or_crashes
- Uninstalling the Windows Update (the last automatic upgrade to MSIE10)
- Uninstalling MSIE via “Turn Windows features on or off”
- Attempting re-installation of MSIE10 and MSIE11 via downloading the full installer http://support.microsoft.com/kb/318378
- System File Checker to repair missing or corrupted system files http://support.microsoft.com/kb/929833
The System File Checker (run within an Administrative CMD window) turned out to be my solution. A number of %windir%\system32 files were corrupted during the automatic upgrade of MSIE. SFC found and fixed all files (without the need to reboot into safe mode, etc.)
Unfortunately, if I’d been paying attention, I could have prevented this using MSIE >> About.
