by entering "regedit" in the run dialog box.
2. Go to the below mentioned path
HKEY_CURRENT_USER\Software\Microsoft\Command Processor
3. Click Command Processor and in the right pane double click "CompletionChar"
4. In the value data textbox, enter 9 and press ok.
5. exit regedit.

restart the command prompt.
