On Windows, Vim installs its binaries to $VIM\vim74. This is extremely annoying when you assign some file types to open with Vim. And while that can be somewhat easily fixed by searching for the old Vim path using RegEdit, you might have configured Vim to be launched in some other programs, too.
TL;DR: Executable paths that change with each update are annoying on Windows.
My program gets rid of the problem by launching the newest (based on the number in the vimXY folder) Vim.
Download vim-launcher.exe, rename it to gvim.exe and copy it right your $VIM folder. If you want a the same thing for the classic CLI-based Vim (does anyone use that on Windows?!), do the same thing but name the file vim.exe.
