 The programs of the [[XDS]] package as well as [[XDSGUI]], [[XDSSTAT]], [[XDSCC12]] and so on may be run on 64bit Windows 10 within the [http://www.pcworld.com/article/3050473/windows/heres-how-windows-10s-ubuntu-based-bash-shell-will-actually-work.html Linux Subsystem for Windows] (WSL). This (easily!) installs a Ubuntu 14.04.5 LTS environment, which supports the apt package manager, so in principle any software available for Ubuntu may be installed.

+XDSSTAT and the conversion to MTZ files by XDSCONV require a CCP4 installation accessible by WSL. In principle, CCP4 may be installed within WSL (have not tested this), or on the Windows host.
-This will then use process-level parallelization instead of thread-level parallelization, and works rather well.
