I have laptop that recently updated to Windows 10. Everything works fine except for the fact I can't read or write files on any USB removable media. Flash drive, Phone, External HD. I have access to the drives and I can actually create folders but If I try to open an existing file or copy it off of the drive I get the message "Access Denied" or Administrator access required. I can read the media in other PC's though.

I have tried formatting a new USB drive and I made sure that the GP wasn't denying access to the USB removable media but to no avail. I have tried different profiles both local and domain as well but I still can't figure out why I can't open files on USB media.  I

I also tried using TAKEOWN command but it doesn't work on a FAT file system.

Anyone have any ideas what could be causing this?
I attached a screenshot of what is happening.

Are there events logged in the Security section of the Event Log that appear to be associated with the problem occurrences?

This is the new security trouble brought by anniversary update on Windows 10.
Are you logged in using default system account of the Windows 10?

I haven't checked the Event log. I will do that and look for some clues.

I did enable the local admin account and try it from there but I still couldn't open any of the files.

Ok, then do you have another PC to connect this drive to and try to open the files there? It might be that the drive itself went bad.

I can open the drive on other computers as well as the files.

I can open the drive on the laptop in question and view it's contents.  I just can't open the files on it nor can I save files to it. It's not just to a specific device. I can't open, create, or move files on any USB media. If a colleague gives me a flash drive with files on it. I can see the files but I get access denied opening them.

Ok, at least we know now that problem is on a software level. How did youtake the ownership?
Can you start a commandline as administrator and then do this:
TAKEOWN /F X:\ /R /D Y
where X is the drive letter of your external drive.

If you right click on any file on this drive - select Properties - then Detail (like on my example) who is the owner of the file?

So there is no ownership of the file.
Can you try it then again to take the ownership?
