Step 7: Disk Cleanup

Disk Cleanup (cleanmgr.exe) is a computer maintenance utility included in Microsoft Windows. It’s designed to free up disk space on computer users' hard drive. The cleanup process firstly involves searching and analyzing the hard drive for files that are no longer of any use. It then proceeds to remove the unnecessary files, freeing up disk space on the hard drive. There are a number of different file categories that Disk Cleanup targets when performing the initial disk analysis:
• Compression of old files
• Temporary Internet files
• Temporary Windows file
• Downloaded Program files
• Recycle Bin
• Removal of unused applications or optional Windows components
• Setup Log files
• Offline files
• And more…

Aside from removing unnecessary files, users also have the option of compressing files that have not been accessed over a set time period of time. This option provides a systematic compression scheme. Infrequently accessed files are compressed to free up disk space while leaving the frequently used files uncompressed for faster read/write access times. If after file compression, a user wishes to access a compressed file, the access times may be increased and vary from system to system. In addition to the categories that appear on the Disk Cleanup tab, the More Options tab offers additional options for freeing up hard drive space through removal of optional Windows components, installed programs, and all but the most recent System Restore point or Shadow Copy data in some versions of Microsoft Windows.

Once you have CCleaner, you may find that there is no need to use this.

As with all cleanups, try not to be doing anything on your computer while it is working.
