Closing those apps from the Task Manager should release the open handles....

Are you copying files from this to a RDP Session?

Yes, sometime I'll use rdp to copy some contents.

Safely remove hardware is only an issue if a file is cached, and not yet physically written to the disk.
I usualy just wait for the led to stop flashing, indicating that write operations have ceased, and pull the drive. I have not ever found a problem

I do use the safely remove hardware if the copy operation is important - just in case

Right click the Drive in Computer Management, and select Policies, and select "Optimize for Quick Removal".....

No share is just a normal pendrive, actually I tried all the pendrive or external hardrive will have the same problem. The default setting for the drive was set to Optimize for quick removal.

ok if still problem persists try scanning them with anti virus may be some hidden faulty program there associated with any running task

Actually not only one usb drive not working but all the usb drive that plug into my system will not be able to unplug. I'll try to do full scan on my system.
