One of the more common tasks which many of the refurbished laptops will undergo is the reinstallation of the operating system. At the time of being refurbished any of the existing data on the hard drive will be erased during the formatting process. These days the actual file systems provide exceptional security mechanisms and have since Windows 2000 was released. The NTFS file system has undergone several refinements and will be the most secure basis for any installation of 2000, XP, Vista or Windows 7 today. This holds true for refurbished laptops as well as any other computers which run the Windows operating systems.
In a practical sense the main benefit of this common process is to create a completely fresh software environment on the refurbished laptops under 200 so that the users are actually starting from scratch. This is how the optimum level of laptop performance will be achieved as it will be in the same state of configuration as it would be if it had just been manufactured. When the hardware is in proper working order and the operating system has been freshly installed on the used or refurbished laptop, the speed and responsiveness of the computer are going to be at their utmost peak level of performance.
This is precisely why this step is a good idea on many used laptops which are beginning to have major issues with software related performance. This is not always the best answer however and bear in mind that this process does basically wipe out all of the existing data stored on the computer. This is essentially how the refurbished laptop arrives at such an optimal level of performance.
