Q:

Windows Explorer Stuck on Cancelling

Does this ever happen to you? When try to copy a file and suddenly you want to cancel it or in my case I was try to write it over a network drive and I lost the connection. 

But regardless what's the reason this annoying box just doesn't go away. Anyone know why this is happening? or How I can prevent such happen over and over again?

A:

Not sure why it happens, but I get it too. To get rid of this annoying dialog you need to kill explorer and restart it:

from Task Manager, Processes tab, find explorer.exe and choose "End Process"
still in Task Manager, select File → New Task → type explorer → OK

A:

Try a copy program that handles exceptions better like TeraCopy or Unstoppable Copier. Both free, fast, and far more reliable than Windows' native copy.
