This problem occurred some days before. It was working before. I used it to delete all the files permanently, but now I guess it has been disabled (I don't know how). Can someone help me out?
No device changes have been made nor any software was installed. The delete button alone is working, which sends the deleted file to recycle bin. And as per the keyboard issue, all the keys are working. This is a laptop and I use external keyboard and I've checked on both of the keyboards, so I don't know what's the cause.
My OS build is 10586.916, version 1511 and edition Windows 10 Home.
