Microsoft recently announced at the Build conference that Windows 10 will soon include Bash, the command-line shell used by GNU Linux and various flavors of Unix.

Starting in January 2016, Windows 7 and newer no longer trust new software signed using SHA-1 certificates. This means developers will need to sign new binaries, INFs and MSIs with SHA256 certificates and time stamps.
