bpo-32507: Change Windows install to include app-local UCRT (#5119)

Misc/NEWS.d/next/Windows/2018-01-07-12-32-49.bpo-32507.vB4gxk.rst

+Use app-local UCRT install rather than the proper update for old versions of
+Windows.

Misc/NEWS.d/next/Windows/2018-01-07-12-33-21.bpo-29911.ewSJKb.rst

+Ensure separate Modify and Uninstall buttons are displayed.

PC/dllbase_nt.txt

-In Win32, DLL's are "pre-linked" using a specified base address.
-When the DLL is loaded, an attempt is made to place it at
-that address.  If that address is already in use, a new base address
-is selected, and the DLL subject to fixups.  Apparently, these
-fixups are very slow, and significant performance gains can be
-made by selecting a good base address.
-
-This document is to allocate base addresses to core Python
-and Python .PYD files, to give a better change of optimal performance.
-This base address is passed to the linker using the /BASE
-command line switch.
