How can we stop Windows 10 from adding the word "shortcut"?
The registry tweak of setting Link to zero in HKEY_CURRENT_USER\Software\Microsoft\Windows\CurrentVersion\Explorer works in Windows 10 Technical Preview build 10130.
I do not know if it will work in build 10074 or if there is some anomaly on your copy which is causing it to revert, which could conceivably be connected to your machine not updating to the current build.
