 Graphical Linux programs require installation of a X server like [https://sourceforge.net/projects/xming/files/latest/download Xming] on the Windows host. To use it, one has to say in the shell window

+Unfortunately, only single-processor xds runs smoothly, whereas the parallel xds_par stops with an error message (supposedly fixed by the CU). The workaround is:
-# since xds_par does not work anyway, just copy the xds binary over the xds_par binary so that it is available under both names (XDSGUI runs xds_par!)
-# in XDS.INP, specify MAXIMUM_NUMBER_OF_JOBS= <number of cores>
+* in XDS.INP, specify MAXIMUM_NUMBER_OF_JOBS= <number of cores> and MAXIMUM_NUMBER_OF_PROCESSORS=1
 This will then use process-level parallelization instead of thread-level parallelization, and works rather well.
-XDSSTAT and the conversion to MTZ files by XDSCONV require a CCP4 installation.
+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.
