Simple text form. Its the same way for IE10/11 and so on.
1. Click the Start button, 2. Click the Control Panel, 3. Click Programs and Features, 4. Click on View Installed Updates on the left-hand side, (Internet Explorer 10 will be shown as an automated update), 5. Right click and choose Uninstall, (This process takes a little while so be patient and do not be tempted to stop the program while it is deleting Internet Explorer 10. Soon you will be asked to reboot the computer for this change to take effect. Do reboot as this will reset the computer to the former version of Internet Explorer 9).
