The system is Windows 8.1 Pro 64-bit, Internet Explorer 11. I reinstalled my operating system within the last week so there's very little in the way of "extras" on here that could be causing this.
The issue is that I cannot start IE unless I run it as an Administrator. Running as an admin works fine. Running it normally will just result in the IE window flashing open and then immediately closing. Looking at Task Manager, it's definitely quitting (i.e. not just getting hidden or anything).
I see nothing in the Windows logs (application or system).
I'm new to Win 8.1 and IE 11, so perhaps there's some good reason for this? Any idea what's happening?
