1. Keep your hard drive clean and uncluttered:

This is one of the easiest tips to follow yet you may have ignored your hard drive for a while.

You simply have to make frequent use of two tools that will quietly run in the background while you go about doing your work. These are:

- Disk Cleanup Utility: Main function of this tool is to eliminate unwanted files from your hard disk o http://windows.microsoft.com/en-us/windows/delete-files-using-disk-cleanup#delete-files-using-disk-cleanup=windows-7

To clean your registry, you can make use of any of the good registry cleaners available in the market. These tools not only provide registry cleaning service, but also provide registry defragmentation, registry backup and restore facilities.
