How do I?
 

How do I clear out old search boxes. Like in wikipedia, I type "a" and a bunch of previous search items pop up under it. How do I get rid of these?

Depending on your browser.

Firefox: Tools > Options > Privacy > Saved Forms
or
Tools > Clear Private Data

IE: Tools > Internet Options > Content > AutoComplete
or something on those lines. You can try clearing the data.

Or grab a performance program like CCleaner and they should erase it for you.

Hmmm. It worked for my IE explorer but not for my MSN explorer. And I don't see any option to clear it out.

I don't know about MSN Explorer as I never use that but you can try a cleaning program. Download CCleaner and see if that does the trick.

where?
