I've also just got a new Win10 laptop and had the same issue with missing mingw64_shell.bat during msys2 install. I solved it by creating mingw64.bat with the following contents:
msys2_shell.cmd -mingw64 -mintty
I deleted all old shortcuts and use this script instead. Everything seems to work fine -- can build GHC.
