Every month is a good time to remove clutter from your computer so it performs well and you can find what you want when you want.
Uninstall games and programs that are no longer used as well as unneeded Desktop shortcuts. In Tools/Security, remove cookies and clear your memory cache and disk cache.
Delete your temp files weekly. Remove Filecheck files in the C: directory (.chk files), created when the computer shut down improperly.
Empty your recycle bin manually and start the disk Defragmenting process, which can take an hour or more.
Turn off features you don’t use, such as Universal Access, Bluetooth, Internet Sharing, Speech Recognition.
Remove Widgets not used recently to avoid using unneeded RAM and processor power. Empty Trash. Remove never-needed fonts, tools and foreign languages and unused applications and their supporting and preference files.
For data, sort to three folders: Active, Archive, Trash. This will speed up your retrieval of active files and backing up retained data. Archive dated files you may need some day. Be ruthless in trashing old files.
When you finish your organizing, back up remaining files and schedule your next maintenance work.
