估计有很多朋友已经知道如何去实现了。

在ms网站上下载的vs2008 RTM版只有90天的使用限制，虽然90天以后，各种各样的破解、补丁都会出来。

但人都会有抢先意识，为何不提前体验无限制的正式版？

解决的办法同vs2005一样，只需更改CD-KEY，然后update即可，

具体的CD-KEY我就不写上来了，大家可以到这里去寻找：

如果还有不明白具体操作的，请看老外的原文：

he following process will upgrade the Team Foundation Server software.
If you are upgrading a dual server installation, this procedure only needs to be completed on the application tier machine.

1. From the control panel open Add or Remove Programs.
2. Select Change/Remove on the Microsoft Visual Studio Team Foundation Server product The Maintenance Mode Options screen will appear.
Select the last option (Upgrade) and enter the CD Key for the version of the software that you are upgrading......

我已经通过该方法将vs2008升为了无限制正式版
