IE11 - Startup Tabs - Restore Last Session Not Working
Solution 1:
I had the same problem as you have and the same system. I went to tools>>> Internet options>>> Advanced settings >>> Go to Enable Caret Browsing for new windows and tabs and put a check mark next to this. I did this and it opened my last browsing sessions. I couldn't before.
Hope this helps and if it doesn't then I would suggest to reset to default and then go back and check the Enable Caret Browsing again.
Solution 2:
This seems to be an issue with Internet Explorer's core system, if your system will allow you to uninstall/re-install IE, I would do so.
You can usually do this in the Windows 'Turn Windows Features on or off' section.
