However, you can rename the system file at the command prompt or shell by typing the following line:
Cannot rename Kernel32.dll: The specified file is being used by Windows.
command ren kernel32.dll kernel32.old
To work around this behavior, use the REN command at a command prompt to rename the file.
Microsoft has confirmed that this is a problem in the Microsoft products that are listed at the beginning of this article.
