Fix Drag and Drop Not Working in Windows 8 Pro
– This is a common problem in Windows XP/7/8 explorer.
– In File Explorer, use the left mouse button to select a file and also keep the button held down. Then smiply press Esc Key once from your keyboard and release it. It will re-enable the drag and drop function automatically.
– If the ESC solution still can’t fix the issues, try hitting both other keys several times, such as Ctrl, Alt, or Windows buttons.
It actually works for me.
