Create a System Password
A top-notch password is vital to protecting your computer from being compromised. Having a weak user-name and password is akin to leaving your wallet exposed among pickpockets. Hackers will stop at nothing to access the private and financial information in your system. To create a great password pick a password that is at least eight characters long, and combines numbers, lower-case and upper-case letters as well as keyboard characters.

If there is highly sensitive information on your laptop, consider encrypting it, especially if you often use the laptop in public places. This ensures that, even if your laptop is stolen it will be almost impossible to access your laptop data. If your laptop runs Windows XP or Windows Vista Business, then you already have a built in file-encryption utility. Windows Vista ultimate comes with Bitlocker, a powerful encryption feature to prevent data theft.

Similarly, if your system crashes, you could lose invaluable data.
