Windows 10: this installation is forbidden by system policy. contact your system administrator

when i try to connect something to my laptop it always says installation is forbidden by system policy.All except a keyboard and an office mouse.But when i try to plug in my phone charger to connect it,it gives my this message,not only that but aso a new gaming mouse i bought and my usb.I dont know whats wrong with it and ive tried lot of things like Prohibit non-administrators from applying vendor signed updates,Software Restriction Policies node and select New Software Restriction Policy and disable.msi.

Installation forbidden by system policy

The device in question is a SanDisk 16gb usb drive. It works ok on this Win 7 computer, and it works ok on another Win 10 computer, but on one Win 10 machine I get this message, "The installation of this device is forbidden by system policy."

What's the fix?
