The first thing we need to do is keep the hard disk clean. I$\text{'}$m talking about getting rid of the stuff on your hard drive you don't need. This is because a full hard drive is a slow drive, as discussed in my lecture. You need to delete the browser cache, clean up your deleted files by using the Recycle bin, and remove temporary files. To remove these files, run your Disk Cleanup Utility frequently because it will remove all these at once.How often should you run Disk Cleanup? Please, explain your answer.
