下载Win7 Ultimate安装盘，用这个KEY安装：

342DG-6YJR8-X92GV-V7DCV-P4K27

在网上寻找并下载DELL的OEM证书：DELL.xrm-ms，然后：

  1. Put "DELL.xrm-ms" in C:\ .
  2. Type cmd in Start menu.
  3. Right-click on the first result (cmd.exe) and click on Run as administrator (confirm by clicking Yes if required).
  4. Type the following:
    slmgr -ilc C:\DELL.xrm-ms
  5. Press ENTER and wait until a message confirms that the certificate has been correctly installed.

Windows 7应该激活了。
