when should I use VS2015 platform toolset V140_XP?

Question

I want to switch from VS2010 to VS2015 but the documentation about V140_XP is not clear to me. I have two questions about it:

1. I use static library(/MT). so I don't need vcruntime140.dll or any other previous runtime library. Should I set platform toolset to V140_XP to run my application in windows XP or not?

2. Will my application run OK on windows 7 and later if I don't set platform toolset to XP?

Answer 1

You only need the v140_XP toolset if you're targetting Windows XP machines (which in new applications you should not be doing).

All later versions of Windows (Vista and up) are supported by the v140 toolset, but applications built with the v140 toolset will not run under XP.
