You: How do you clean out the cache in IE

Virtual agent: You can use the following steps to clear your temporary files, cookies, browsing history, or other personal information in Internet Explorer:

Click Safety from the Command bar.
Select Delete Browsing History from the menu.
On the pop-up page, select the check boxes next to the items you wish to remove.
Click Delete to clear your personal information.


In Internet Explorer 9, the Command bar is hidden by default. You can enable the Command bar by pressing the ALT key and then click View -> Toolbars -> Command Bar.

If you have problems deleting history in Internet Explorer, click Tools –> Internet Options –> Content tab –> AutoComplete and uncheck the Use Windows Search for better results box.

If the problem remains or if you have problems saving history in Internet Explorer, you can visit the Microsoft Answers Community, where Microsoft MVPs will address your specific issues and make further investigations.
