אחת מה"תכונות" היותר מדוברות (לרעה) על ה-Windows XP היא ה-Activation.
אם עד עכשיו עדיין אין לכם מושג מה זה בעצם, המאמר הזה הוא בשבילכם!
One very important thing to note is that if you reinstall Windows XP on the same PC without hardware changes, you can reactivate as many times as you want, without questions being asked. While it's most convenient to activate by the Internet, you can activate by phone without questions. If you do activate the first time by phone, and make a note of the activation key, you can reenter it when you reinstall later. If you just add memory, or change a graphics card, the weight on these components may be low, and XP will keep chugging thinking its being reactivated on a different computer. The network adapter (NIC) is the component that weights the most and makes a difference in Windows XP deciding if it's a reactivation on the same or different PC. Gamers, try not to use a different NIC card while you are at a LAN party
