Windows XP Security Tips

In our days all of us, we use a computer in a small network connected to internet, in our home or in a biggest network in our job for work, information or just entertainment.

However, over time the security risks are increasing but a lot of simple users or small companies, they don't know how to protect themselves from viruses, internet computers attacks, or data abstractions.

At this post, i 'll try to give some personal advices, for your own protection in Windows XP environment , from my experience until today.

1. First of all choose the Windows XP Professional Edition instantly Windows XP Home Edition, for operating system in your computer.

And this, because unfortunately Windows XP Home Edition, doesn't have all of the security features of Windows XP Professional Edition.

2. Use a strong password for each user account you have at your computer. A big security risk at Windows XP installation, is that Administrator account already exists but has a blank password. If a little expert user tries to log on in your machine using this account in safe or normal mode, then he will have full access in your data and in all of your computer settings and information.
