It's really luck.
I went home from get off work yesterday, I found out that OEM's Lenovo XP SP2 could not be online Update. It seems that MS is really crazy.
Helpless, I have to fix XP installed another Edition. I didn't expect to install it. Even if I selected security mode, it was directly restarted, and later analyzed is related to the virtual drive. I have to format the installation, very tossing. A lot of software in the computer is heavy, 唉 ~~~~~~
MS, very crazy.
