Windows 2000中在cmd命令符下Tab实现自动补全

To enable automatic complete for Cmd.exe, use Registry Editor (Regedt32.exe) to view the following registry key:
HKEY_CURRENT_USER/Software/Microsoft/Command Processor
Edit the CompletionChar value, and set the value of REG_DWORD to 9. Note that you do not need to restart your computer.

在注册表中找到：HKEY_CURRENT_USER/Software/Microsoft/Command Processor
设置CompletionChar为9即可。
