来自国外的方法，原文是这样的：
Microsoft "Genuine Advantage" cracked in 24h: window.g_sDisableWGACheck='all'
AV sez, "This week, Microsoft started requiring users to verifiy their serial number before using Windows Update. This effort to force users to either buy XP or tell them where you got the illegal copy is called 'Genuine Advantage.' It was cracked within 24 hours." Before pressing 'Custom' or 'Express' buttons paste this text to the address bar and press enter:
javascript:void(window.g_sDisableWGACheck='all')
It turns off the trigger for the key check.
大概的意思是：
在你登入Windows Update网站时，当提示“快速”和“自定义”时，在地址栏填上：javascript:void (window.g_sDisableWGACheck='all') 当然要Enter回车确定啦，然后再选“快速”和“自定义”就可以了。
经测试有效！
