Z Drive Windows 10

This is the second or third time this has happened. I randomly have a Local Disk (Z:) on my PC. It is always small, between 200-500 MB. When I click on it, it says,'You don't currently have permission to access this folder.

Click Continue to permanently get access to this folder.' When I click 'Continue'. It says, 'You have been denied permission to access this folder. To gain access to this folder you will need to use the security tab.'

I am unable to gain access no matter what. Does anyone have any idea why this is happening? Dbeato wrote:That is most likely the system reserved partition on the system that was mounted by Windows 10.DaveA-DoIT wrote:It's happened to a few of my users on 10.

In our case it was the recovery partition and the users definitely didn't manually set a drive letter, it just happened on its own. It isn't a recovery partition. I have my regular c drive, a recovery partition, and the Z: drive.Michael Perez wrote:A recent update made this appear for some users on Windows 2012 R2, once we rebooted it went away. I think it is some sort of staging area for updates.I am actually thinking that is what it is as well.

I read up on it a bit and a lot of other people have had the same thing happen to them. There is some speculation, but no one has a definitive answer yet.
