Sysinternals has released a command-line utility that can view and manage handles ( ), so I've decided to create a batch script that uses this utility to enable the classic theme in one click. By doing this, theming is disabled, and any new applications will fall back to the Windows Classic theme. It turns out that the Windows 98 style classic theme still has not been removed after all! I figured out that it's possible to enable it by closing the handle to the ThemeSection object in the winlogon.exe process.
