DWS stands for Destroy Windows Spying, and was developed as a tool that should prevent Microsoft from obtaining any information in concealed ways. As such, it blocks communication of all software with Microsoft's servers, so don't be surprised why something all of a sudden stopped working, especially if it ought to connect to Microsoft(Store, Skype,..), but even if there is no apparent reason, for a software, to connect to them in order to work properly, it still going to be blocked which can upset it very much and it will refuse to work at all even if the connection is not necessary.
