Congratulations to Microzoz who thought to block the data of dragging for a System Protection in win10....HA..HA..HA.
Here the registry modification that unlocks protection:
Code:
HKEY_LOCAL_MACHINE > SOFTWARE > Microsoft > Windows > CurrentVersion > Policies > System
Change "EnableLUA" 1 to 0.
Reboot Your System ...
I remain convinced that win7 will be much longer a valid system...
Soon new updates ...
Edit : The version posted with registry modifies the DnD works perfectly in win10.
