前两天买了一盘xp home edition的正版，分别装在了两台电脑上，上网后要activate windows, 所以其中一台就先activate了，结果是不是另外一台就不可以了？这种正版的光盘是不是只能用一次？而且只能用在一台电脑上？谢谢！

把你电脑的机器号给另一个人应该就可以了

不过搞不明白他装还有什么用？连所谓正版的那点心理安慰都没有，还不如网上下载Pro原版算号。

there is more difference than just a license.

My pirated windows XP still can be approved. Can there be any spyware?

The genuine validation process will collect information about your system, such as Windows product key, PC manufacturer, and operating system version, to determine if Windows is genuine. The complete list of information collected in the validation process is shown below:

OEM product key
PC Manufacturer
OS version
PID/SID
BIOS info (make, version, date)
BIOS MD5 Checksum


Q. What if my copy of Windows fails the validation process or I believe I have received pirated software?



A. In either case, Microsoft recommends the following steps: First, turn on Automatic Updates to make sure your system is being protected while you are resolving the problem. Second, use the resources on the Windows Genuine Advantage pages to learn how to recognize genuine Windows software. Third, see your reseller and ask for genuine Windows software, using a print-out of the validation session for support. Finally, if you can't get assistance from your reseller and you suspect you’ve been victimized, fill out a Report Piracy Now report so Microsoft can have a record of the transaction and determine if addition action is warranted.
