Microsoft Windows 7 USB DVD download tool is very capricious, long time is not updated, doesn’t work in many cases (can after spent long time to copy 2-4gb, only in the end of process suddenly cast error that couldn’t create boot records; or doesn’t work on other version of windows and so on). Therefore i prefer to use tiny rufus utility. It’s free and very small – less than megabyte. Doesn’t need to be installed – portable – ready to work immediately after download. Very stable work to create Windows install disks for any edition and version, including windows 10 and windows 2016.
