Before you run the cleanup utility, you must decide what to delete. [See Image 3] If you make your selections carefully, you can improve performance while minimizing how long Disk Cleanup takes to run. Here's what you might see:
- Downloaded Program Files - These files download automatically when you view certain Web pages.
- Temporary Internet Files - These files contain copies of web pages you've visited.
- Offline Webpages - These files are web pages you opt to view without being connected to the Internet.
- Games News Files - RSS files accumulated from games you play.
- Recycle Bin - These are the files in the Recycle Bin. Note that files are not permanently deleted until you empty it.Setup Log Files - Files created by Windows during setup processes.
- Temporary Files - Files created and stored by programs for use by the program.
- Thumbnails - Files that represent icon for pictures, videos, and documents.
- Per user archived Windows Error Reporting - Files used for error reporting and solution checking.
- System archived Windows Error Reporting - Files used for error reporting and solution checking.
You may also see items like Zune temporary converted files and other odd entries. Click and read what these files are, and delete them if you're comfortable doing so.
As noted, you may also access the More Options tab, where you can remove programs that you do not use; you may not. This tab is shown only on certain systems that meet specific criteria. Clicking Clean Up from this tab opens Control Panel, where you can view installed programs and remove the ones you don't use. If you purchased your computer from a "Big Box" store, you probably have lots to get rid of. Do it. Also from the More Options tab, System Restore and Shadow Copies Clean Up option lets you delete all but the most recent restore point s(which I won't suggest), and old backup images.
