A standalone redistributable installation before, Debugging Tools for Windows was finally absorbed into Windows SDK. MSDN quote from Download and Install Debugging Tools for Windows:
Install Debugging Tools for Windows as a Standalone Component
If you do not want an entire kit (WDK or SDK), you can install the Debugging Tools as a standalone component from the Windows SDK.
TO INTSTALL JUST DEBUGGING TOOLS: In the SDK installation wizard, select Debugging Tools, and clear other components that you don’t want. Note that .NET Framework 4.0 also will be installed.

Install Debugging Tools for Windows without Installing .NET Framework
If you do NOT want to install the .NET Framework, there are additional steps needed.
Start the install process on a different computer where it is okay to install the .NET Framework. The installer requires .NET Framework 4.0 or higher, and will install .NET if it is not already installed.
Install the Debugging Tools as a standalone component from the Windows SDK. In the installation wizard, select Debugging Tools, and clear other components that you don’t want.
After installation is complete, go to the program files directory and look for (%Program Files%)\Windows Kits\8.0\Debuggers\Redist.
Copy and run the applicable MSIs on the computer that cannot have .NET.
Also, Windows SDK for Windows 8 Consumer Preview is not available as ISO download. So you have to use web downloader, install the gear, and having gone through this, the .MSI of interest are finally there.
You gotta be kidding me, though still thanks for not removing those completely.
