operating system will slow down and might produce errors. Click Start Computer.
2. Empty your recycle bin on a regular basis.
3. Use disk defragment tool regularly on your hard disk drive to improve data seek and read times.

Note: You might also want to look for application program duplication or overlapping versions.

System Restore, see Chapter 5 “Recovery overview” on page 63.
