How To Configure and Use CCleaner

While it is said that the CCleaner may improve your computer performances, it is important to make sure CCleaner is set up correctly.

What is CCleaner?

CCleaner or “Crap Cleaner“, just from the name itself we can learn, or at least guess, its function is to clean the crap files from Windows® in order to increase the computer performances.

The Windows® Utility Tool’s size is quite small, only 5 MB. Despite its tiny size, the tool has plenty of use such as to clean the no-longer-needed file from windows like temporary files, broken shortcuts, browsing and internet history in your internet browser, unused registry and to disable unimportant startup programs which run from the start as Windows® running.

To improve the computer performance by using CCleaner you need to make sure that you make the right setting. It is worth noting that you need to be real careful deleting files with CCleaner.

Here are the sections of CCleaner explained in detail for you:

Internet Explorer Files

Temporary Internet Files – These are HTML files, images, JavaScript files, and other files that Internet Explorer saves as you browse so that if you go back to the page, it can quickly pull the files from the disk instead of having to request them again from the server.
Cookies – For a further discussion of cookies, please see the Choosing which cookies to keep topic.

History – Internet Explorer stores pages you’ve visited and the time and date you visited them.

Recently Typed URLs – Internet Explorer saves your recently-typed URLs so it can suggest them as you type new URLs with the same starting letters. This rule removes them.

Index.dat files – These files function as an index for the browser, and store temporary information about URLs, search queries, and recently stored files to speed up browser operation.

Last Download Location – Internet Explorer remembers where you downloaded the last file.

Cached Feeds – Web feed is a data format used for providing users with frequently updated content. If deleted, it will be redownloaded upon next Browser restart

Add-ons Statistics – Internet Explorer stores all internal statistics about add-ons, which were installed on IE.

Autocomplete Form History – Once you’ve used Internet Explorer for a while, you’ll notice that as you start typing letters into a text box on a form, it will present you with suggestions. Note: Using this cleaning rule will also deleted your saved passwords.

Saved Passwords – Internet Explorer stores passwords for pages you’ve visited.

Windows Explorer Files

Recent Documents – This option clears the list Windows Explorer maintains of your most recently-opened files (see, for example, the My Recent Documents item on the Start menu).

Run (in Start Menu) – This option clears the list that the Start Menu’s Run dialog box maintains of programs you’ve run from it.

Other Explorer MRUs – Windows Explorer also maintains Most Recently Used (MRU) lists for the following types of information: Find Files, Find Computer, printer ports, and streaming data. If you select this check box, CCleaner will also clean the breadcrumb records used by Windows 7 (breadcrumbs appear in the Explorer path box and display the path you took to get to a folder).

Thumbnail Cache – This option clears the Windows Explorer image thumbnail cache, which is maintained to speed up the browsing of folders containing photos and images. But it will also contain the thumbnails of images that are no longer on the system. (This rule is for Window Vista only.)

Taskbar Jump Lists – When CCleaner is minimized to the taskbar, clicking right mouse button on its icon you will show you Jump List Tasks of CCleaner.

System Files

Empty Recycle Bin – If you select this check box, CCleaner will empty your Recycle Bin.

Temporary Files – CCleaner will delete the Windows temporary files which are not in use. By default it only removes files that have not been accessed in 48 hours. This can be changed to clean all temp files in the Advanced Settings.

Clipboard – CCleaner will clear the contents of the Windows Clipboard.

Memory Dumps – When Windows crashes, it stores small memory dumps so that technical users can debug their systems. CCleaner will delete these files.

Chkdsk File Fragments – These are clusters and chains that are left over after you run CHKDSK. CCleaner will delete them.

Windows Log Files – Windows logs many events and activities, such as access, policy changes, Internet use, tasks, and so on. As a result, the dozens of logs it creates are scattered across the system. They will all be deleted by CCleaner.

Windows Error Reporting – (Vista only) Whenever a program crashes, Windows saves details of the crash to report back to Microsoft. This option will clean all the error reports from your system.

DNS Cache – When you visit a Web site, Windows attempts to speed up future visits to that site by writing its DNS information to the DNS cache. This option will clear out the cache so that Windows can start storing DNS information from scratch.

FTP Accounts – All available FTP accounts with their usernames and passwords to the servers are remembered in the system.

Start Menu Shortcuts – This option will delete Start Menu shortcuts that are invalid (they point to files that no longer exist).

Desktop Shortcuts – This option will delete desktop shortcuts that are invalid (they point to files that no longer exist).

Advanced Windows Files

Old Prefetch Data – To run quickly, Windows uses prefetch files to store information about programs that you frequently use. The Cleaner deletes old prefetch data for programs that no longer exist or haven’t been used in a long time.

Menu Order Cache – When you drag and drop items on the Start menu into different locations, Windows stores this information in the Menu Order Cache.

Tray Notifications Cache – This cache stores information about any items that have ever appeared in your System Tray, and whether or not you have set them to Hide, Hide When Inactive, or Always Show.

Window Size/Location Cache – When you open and close Windows Explorer, Windows records folder settings for window position, sort order, columns, folder type, toolbar toggles, and search result views.

Environment Path – TBA

User Assist History – User Assist History is a built-in monitoring feature of Windows that records when you access programs, shortcuts, Control Panel applets, and possibly even Web sites.

IIS Log Files – Microsoft’s IIS server keeps logs of its activities on your system.

Hotfix Uninstallers – (XP only) Every time you download and run a Hotfix from Microsoft, Windows stores an uninstallation program for that Hotfix on your system.

Custom Files and Folders – This setting relates to CCleaner rather than any part of Windows. If you select Custom Files and Folders, CCleaner will use the information in the Include and Exclude part of its Advanced section to add or ignore files, folders, and Registry keys while cleaning.

Wipe Free Space – When you delete files from your hard drive, Windows only deletes the reference to the files, not the files themselves. Over time, the contents of the files will be overwritten as Windows writes new files, but it’s possible to recover some or all parts of deleted files.

Applications Tab

Web Browsers

(for example, Mozilla Firefox, Google Chrome and Safari)

Cookies – Web cookies stored by each browser. Note that the cookie list in the Options section of CCleaner controls cookies for all browsers you have installed, not just Internet Explorer.

Download History – A list of files you downloaded through that browser.

Session – You can save the session and reopen it at the later time. Session contains all saved and opened tabs.

Internet Cache – HTML, images, and other files accumulated while you surfed the Web using that browser.

Internet History – A list of the sites you visited and the dates on which you visited them.

Saved Form Information – User names, passwords, search terms, and anything else you typed into any forms that appeared in the browser’s HTML canvas.

Compact Databases – Some Web browsers (notably Mozilla Firefox and Google Chrome) use databases to store bookmarks, history, and other data. When you remove information from these databases, they may still take up room with fragmented space. If you select Compact Database, CCleaner will defragment and trim unused space from these databases.

Website Icons – Some browsers store website icons which are displayed on the address bar and in the favorites list.

Saved Passwords – Web browsers can store passwords for pages you’ve visited.

Other Applications and Utilities

Applications – These refer to third-party applications you’ve installed that don’t fall under the Internet, Multimedia, or Utilities category. Some examples are CD/DVD-burning programs and word processing software.

Internet – These programs include browser add-ons such as Flash and the Google toolbar, instant messaging programs, and firewalls.

Multimedia – These programs are video players and editors, or video helper programs for Web browsers.

Utilities – These include utilities such as Zip management, disk tools, and spyware scanners.
