I have the same issue here. 5 windows 10 machines all with NoMachine 5.2.11 or 5.1.42 we working well before the windows 1607 update. Now the nxservice won’t run at startup and the nxserver stops running as started. 1607 Windows home update appears to be generally toxic to NoMachine and all connections fail. The only device still working is an android tablet but it is only a client so it has nothing it can connect to 🙁 help?
