Every time you visit a web page, your web browser stores or ‘caches’ it as a small file in your Temporary Internet Files folder. Over time, the volume of these files can build up. Clearing out your browser’s cache will help it to work faster when loading pages and reduce the amount of valuable disk space these cached files take up.
In Internet Explorer 9 and 10, click Tools > Safety > Delete browsing history. Tick the checkbox next to Temporary Internet files. You can also choose to delete your web browsing history and cookies here. If you don’t want to delete cookies and files associated with websites in your favourites list, select the Preserve Favorites website data checkbox.
It’s also a good idea to reduce the number of installed add-ons. These small programs add features to your web browser, such as extra toolbars, but can also slow down your web browsing. To view all installed add-ons in Internet Explorer 9 or 10, click Tools > Manage Add-ons. Then under Show, click All add-ons. To turn off an add-on, click an item, and then click Disable. Repeat for all the add-ons you want to remove and then click Close.
