I'm also using the Insider Preview of Windows 10 (though I am on the slow update ring) and (at least) on version 1703, build 15063.138 I have no trouble running DMD. Also, can you check if Windows Defender isn't mistaking the compiler for a virus (e.g. by white-listing it or temporary disabling the protection)? There have been some reports about certain anti-virus/malware programs wrongly detecting dmd as such, though I don't think Windows Defender has been mentioned before. Finally, can you give some more information on how are you running dmd? Command Prompt, PowerShell, Windows Subsystem for Linux (bash.exe), MinGW or some IDE? Is there some error message or backtrace that gets printed? Also does dub run ok? (You can testing by fetching a package - e.g. 'dub fetch dscanner'.) --
