I know that some applications also install these Microsoft Visual Studio C++ Redistributable Packages.
If I remember correctly, then the SmartFTP Client installs them (to give you an example).
Due to the following article some instances can also be delivered with Windows 10 itself:
Some are installed along with Windows itself. The specific versions that get installed depend on which version of Windows you’re using. I’m using Windows 10, which comes with the 2012 and 2013 Visual C++ Redistributables
I thought it might be a good idea to bundle them with Windows, because:
They are located in the Windows folder
You can not determine what application installed them (or can you get this information from the registry???)
How to proceed?
