The Internet Explorer has many security enhancements, that make it less susceptible to malware. However one can never be too sure ! Moreover, badly written add-ons can also affect the browsing experience in IE. Often we find that our once fast browser has become slow to start and use. Over a period of time, we may install and uninstall add-ons, plugins and toolbars. Should you find that your Internet Explorer freezes or is not working the way you want to, you can easily
reset Internet Explorer settings to default. This is called the RIES feature of IE.
Reset Internet Explorer Settings
To reset Internet Explorer Settings to default,
open IE >
Tools >
Internet Options >
Advanced tab >
Click Reset >
Close >
OK. Once this is done restart Internet Explorer. But before you use the reset button, there are a few things you should know.

When you click on the Reset Internet Explorer button,
the following will happen:
1. Toolbars and add-ons get disabled
2. Web browser settings revert to default
3. Privacy & Security settings are changed back to their default values
