Uninstall Windows Anytime Upgrade / Windows 7?

I want to uninstall Windows Anytime Upgrade from my systems HDD and gain back all the drive space it takes up ..I found one link to the Lenovo Support that describes how to remove it from Vista, but nothing pertaining to Win7 ..http:[url].....

On the Lenovo Support page:

User may want to gain back approximately 3GB in hard drive space by removing the Windows Anytime Upgrade. Windows Anytime Upgrade software may be preloaded on any Microsoft Vista preload system except for Vista Ultimate.How to uninstall and delete WAU Bits from Preload.

Open a Command Prompt with Administrative Privileges:

Click All programs then click Accessories, then right click on Command Prompt and Run as Administrator.

Click on Continue message on the dialogue box with "Windows Need your permission to continue"

Change directory to the root of C Drive by typing CD from the "C:>" prompt.

At the CMD prompt type attrib -r WAUUPGRD

Type RD /S /Q WAUUPGRD

Warning: Make sure you type it in exactly as shown above.The RD command with the /S option will delete all directories and subdirectories contained within the directory specified. The / Q command turns off the prompt asking if you are sure you want to do this. Once you run this command, you can not undo it. This will remove Windows Anytime Upgrade from the preload.I did attempt to follow the Command Prompt steps they offered, but couldn't get it to work ..here is what I got (pasted from Command Prompt window)
