Internet Explorer 10 is not compatible with many online banking sites and a host of other websites not yet upgraded to render properly in this brand new browser release.
During the month of March, Microsoft will be making its Internet Explorer 10 browser available for Windows 7 and 8. This browser update will be automatically propagated and installed as part of the next Microsoft Windows update.
Preliminary testing has identified compatibility issues between the new Internet Explorer browser and many online banking sites.
Since many banking sites do not support Internet Explorer 10 at this time, we STRONGLY RECOMMEND THAT YOU DO NOT install the new browser on computers that access any cash management or banking sites.
If you insist on installing IE 10 or the Microsoft auto-update gets past you and find that you can’t remove it to roll back to IE9, there is a workaround.
To force a webpage you are viewing in Internet Explorer 10 into a particular document compatibility mode, first open F12 Tools by pressing the F12 key. Then, on the Browser Mode menu, click Internet Explorer 10, and on the Document Mode menu, click Standards.
This special mode will allow most incompatible sites to work for you. This is by no means guaranteed and your success with this workaround may be limited.
