You need to evaluate them inside Emacs: M-: system-configuration RET M-: system-configuration-options RET > Both are precompiled version I downloaded; the 24.3.50.1 from dropbox: > https://www.dropbox.com/sh/3pgcb3iiy8s9irl/c171Xhsd99 I'm quite sure the release binary is optimized, while the snapshot one is not. > (I wasn't able to compile it myself on windows; I tried it, but I wasn't > able to find all prerequisites. This is really easier on linux.) Latest versions compile like on GNU/Linux, you just need to create a suitable environment first, using the advice in nt/INSTALL.
