I don't know if this is the right place to report a bug, but the Remote Desktop client for WVD does not work with userprofiles containing spaces. When subscribing to a feed it does show the applications, but without icons. When trying to open a application it gives the following error message:
Here you can see it tries to use the connection file, but the filepath has been split at the point where the space is. When renaming the profile to not include a space it works as expected.
It seems to be the same problem as with scripting generally when paths are not encapsulated with quotes ".
