Win10 upload done arduino not working


I can upload BLINK and it works with win10 PC.

When I upload a big sketch the upload finish OK but the arduino does nothing

This same sketch ,cable and arduino works on win7

Is there a known problem with win10 buffer size?(with arduino)

Any ideas as where to start debug?
