一 | 8月26日消息，前微软工程师Dave Plummer近日揭秘了Windows XP时代最著名的盗版密钥FCKGW-RHQQ2-YXRKT-8TG6W-2B7Q8的真实来源，这串字符并非黑客破解生成，而是一把泄露的企业批量授权密钥。 MIAMI -- Tropical Storm Tammy formed Wednesday afternoon in the Atlantic Ocean, putting a group of islands on alert for its expected approach.The Miami-based National Hurricane Center said Tammy was centered at 5 p.m. EDT about 625 miles (1,005 kilometers) east of the Windward Islands. It was moving briskly to the west at 23 mph (37 kph) and expected to gradually strengthen in coming days.Tropical storm watches have been issued for Barbados, Dominica, and Martinique and Guadeloupe. Forecasters said tropical storm conditions were possible in the region starting within 48 hours and that further watches and warnings will likely be required Wednesday night or Thursday. Tammy is initially expected to spread heavy rains over the northern Windward and Leeward Islands through Friday and then across the U.S. and British Virgin Islands and Puerto Rico over the weekend, according to the hurricane center.The center's opening advisory on Tammy said total rainfall could measure between 3 and 6 inches (7-14 centimeters) with maximum amounts of 10 inches (25 centimeters) in some spots in the northern Windward Islands and Leeward Islands. Lesser rainfall amounts are expected in the British and U.S. Virgin Islands into eastern Puerto Rico, the hurricane center added.The prospect of heavy rains as Tammy nears those islands raises a threat of scattered flash flooding, urban flooding and isolated mudslides in higher terrain, according to meteorologists.。 Windows XP是首款引入产品激活校验技术（WPA）的Windows系统，在此之前，用户安装系统只需输入产品密钥即可完成激活，没有额外校验。

二 | WPA则在产品密钥基础上增加了硬件ID校验，安装时系统会生成一个基于主板、CPU、硬盘等硬件信息的硬件ID，将硬件ID与产品密钥一起发送到微软服务器验证。如果密钥在另一台硬件配置不同的电脑上使用，就会被标记为盗版，这套机制有效阻止了单个零售密钥在多台电脑上重复使用。 但微软同时为企业客户提供了另一套激活通道：批量授权密钥（VLK），毕竟拥有数千台电脑的企业不可能逐台输入密钥走激活流程，VLK允许企业跳过WPA的硬件校验环节直接批量激活。微软信任购买了批量授权协议的企业不会将这些密钥外泄，因此VLK在设计上没有绑定硬件校验，而正是这一信任成为了整个事件的突破口。 Plummer表示，微软当时对企业客户的信任是激活设计中的关键假设，而这一假设被证明过于乐观。 FCKGW这把密钥就是一把合法的企业VLK，某家企业的批量授权密钥流出后，有人将其与企业版安装镜像搭配使用，这串密钥随后在互联网上迅速传播，出现在无数刻录CD和预激活版Windows XP安装包中。 对于整整一代PC用户来说，FCKGW就是Windows XP密钥的代名词，甚至很多人不知道这串字符代表什么，只知道装系统时输入它就能用。 Windows XP于2001年8月24日交付OEM制造，距今已25年，微软当时对待盗版的态度与今天也是截然不同。 2000年代初Windows是微软的现金牛，Office等产品的销售也依赖Windows的装机量，打击盗版直接关系到营收。
