题解：

　　你是PCJOB的网络管理员，Tess，公司财务部的一名员工，想要升级那台连接到自己的Windows 2000 Professional计算机的打印机，以便于自已可以用更高的解析率来打印图形，Tess从互联网上下载了一个打印机驱动程序，然后请你帮她安装该驱动。但你不能确定这个驱动程序的安全性，你不希望因为驱动程序的兼容性问题而耽误用户的工作时间，这样的话，你需要怎么做？

　　与Windows 2000 一起提供的系统文件有一个Microsoft数字签署。它能确保特定的文件满足一定的测试级别，并且可以确保该文件不曾被更改，也没有被另一个程序的安装过程覆盖写入过。

　　有时候，在你的计算机上安装新的软件时，软件安装过程会用一个不兼容的版本覆盖写入系统文件，这就可能导致系统的不稳定性以及不安全性。
