Windows 7 也支持时间延长法

Win7之家（ www.win7china.com）：Windows 7 也支持时间延长法

 按照微软Pre-beta版本软件的惯例，Windows 7 Pre-beta也将会是个定时炸弹，也就是说，你最多可以用到2009年8月1日，尽管通过winver命令我们可以看到时间限制为2009年7月1日。无论是否有产品密钥，Windows 7 Pre-beta，包括6801和6956，都可以用到2009年8月1日。

在Windows 7 Pre-beta的用户协议中也有有关此时间的说法：“此软件将会在2009年8月1日时自动失效。除此之外，你不会收到其他任何通知。当系统失效时，你将无法取得与此软件相关的数据。”

事实上，即使你通过种种方法激活了Windows 7 Pre-beta，如使用泄露的key或其他小技巧等，系统还是会在2009年8月1日自动失效。而到期后，用户其实无需重新寻找可用key等方法去激活系统，因为，Windows 7和Vista一样，也是可以通过软件许可管理器或SLMFR.vbs时间延长的。

在Windows Vista, Windows Server 2008, Windows 7, and Windows 7 Server (Windows Server 2008 R2)中，用户可以通过Slmgr来延长系统的试用时间。在Windows 7中，用户可以通过slmgr -rearm命令延长试用期达120天。每次输入命令后，系统试用期将会延长30天。

另外，2009年8月1日的时间限制也适用于Windows 7中用户许可协议。“此用户协议将会在2009年8月1日时失效。在此期间，你可以在此协议下使用改软件。但如果你没有产品密钥的话，你将不得不每30天重装一次系统。”

附部分原文：

The development milestones of Windows 7, be them pre-Beta or fully-fledged Beta, are time-bombed, as is the case with all Microsoft pre-release software. When it comes down to the Milestone 3 releases of the next iteration of the Windows client, the expiration date is officially set to August 1, 2009. This despite the operating system indicating via Winver that it will expire as early as July 1, 2009. With or without a product key, pre-release versions of Windows 7 including Build 6801 and 6956, but not earlier than 6801, can be used up until August 1, 2009.

The expiration date of Windows 7 is delivered under the Time Sensitive Software section of the End User License Agreement. “This software will stop running on August 1, 2009. You may not receive any other notice. You may not be able to access data used with the software when it stops running,” Microsoft informs.

Indeed, even development milestones of Windows 7 that are activated using a genuine or a leaked product key, or by any other workaround, will stop running come August 1, 2009. Still, when it comes down to activation, users needn't resort to cracks or leaked product keys. Windows 7, even in the pre-release builds, supports rearming, just like Windows Vista. This is done via the Software License Manager or SLMGR.vbs. Slmgr is a tool that, as its name implies, permits end-users to deal with the various aspects of licensing.
