```

Any suggestions? (I tried re-installing but the same issue shows)

Answer: 
Yes!!!! I found sol'n

Un-install IE using control panel.
Install it again and make IE default browser with recommened settings.

and you done.

Worked for my case
Update of IE is not an option for me. I need it for testing on this machine. In my case following helped me:

I opened developer tools of IE8 (press F12). It was in 'IE8 Compat View' mode. I switched to 'IE8' mode and specified Document mode to 'IE8 Standards'.

Then I were able to sign in to TFS through IE8. Once I signed in using browser I restarted Visual Studio and everything worked correctly.
