Here is a list of routine maintenance you should be performing on your computer each and every month. If you use your computer on a daily basis or surf the net everyday, you should perform this maintenance weekly. There are other things that many people do on a monthly basis, but here is what EVERYONE needs to do, at least monthly and how to do it:
Clean out all temporary files -- you don’t need any of them and they just take up valuable hard drive space.
Clean out your "cookies"(电脑中的一些数据)—the things that lead internet trackers back to you. Remember that if you clean out all your cookies, you will have to log back into any sites you set up to log you on automatically—such as this site.
Empty your trash can / recycle can -- again taking up valuable hard drive space.
Get rid of all Spyware.
Run a Virus Scan.
Shake out and clean your keyboard.
Run a scandisk to check for any errors.
