#595 Mingw-w64 installer Start Menu shortcuts misplaced

[pal100 rep0roc]

Due to some unpleasent issues I had with Msys2 mingw-w64-i686-toolchain, I decided to go stand-alone.
Your installer request Admin priviledges immediately, and because of this it should definitely place the shortcuts in All Users Start Menu, unfortunately it places them in Admin user Start Menu folder. At least, this is what happened on my Windows 10 system. Most users would think that Start Menu shortcuts creation simply failed. Moving the shortcuts around is messy. You have to use an elevated file manager, followed by files permissions editing.

All Users Start Menu locations:
Windows XP: %ALLUSERSPROFILE%\Start Menu\Programs
Windows Vista/7/8/8.1/10: %ALLUSERSPROFILE%\Microsoft\Windows\Start Menu\Programs
