How often to update Internet Explorer

While it's true that the more files you can load from your hard disk, the faster your browsing speed, it's also true that those pages on the Web might have changed since being stored on your computer. You might not want to miss fresh content just to save a little time. Fortunately, in addition to the size of the cache, you can also customize how often Internet Explorer 6 checks the Web for updated content.
First you will need to go to the Internet Explorer 6 Settings box:

1.	Steps to Follow  On the Tools menu, click Internet Options. The Internet Options box should open to theGeneral tab.
2.	On the General tab, in the Temporary Internet Files section, click the Settings button. This will open the Settings box.
3.	In the Settings box, there are four ways to check for newer versions of pages that are stored in the Temporary Internet Files folder:  •  Every visit to the page: You're assured of the most current content, but it's slower to browse previously viewed pages. •  Every time you start Internet Explorer 6: On your first visit to a page, Internet Explorer 6 will check for new information, but not on subsequent visits in the same browsing session. •  Automatically: Internet Explorer 6 will check automatically for any new content. •  Never: This option is fastest, but you could be viewing old content from the cache. To refresh the page, press the F5 button on your keyboard—this will connect you to the page on the Web and download new information to the Temporary Internet files folder.

Try several combinations of these options and cache size to find the best fit for your needs. You may need to use the settings for a few days to fully gauge how they are working.
