I have a Windows to Go drive that I'd also like to use as a normal flash drive.

However, I can't move files to the root directory, or copy files there. Attempting to do so produces this error:

An unexpected error is keeping you from creating the file. If you continue to receive this error, you can use the error code to search for helm with this problem.

Error 0x80070522: A required privilege is not held by the client.

Looking around for a solution seems to turn up fixes that apply for a locked-up C: drive, but this drive isn't C:, and turning off my own personal UAC doesn't sound portable.

Note:

Giving Everyone Full Control in the security settings does not seem to help.

E: NT AUTHORITY\Authenticated Users:(S,AD)

NT AUTHORITY\Authenticated Users:(OI)(CI)(IO)(M)

NT AUTHORITY\SYSTEM:(OI)(CF)(F)

BUILTIN\Administrators:(OI)(CI)(F)

Everyone:(OI)(CI)(F)

BUILTIN\Users:(OI)(CI)(RX)

Mandatory Label\High Mandatory Level :(OI)(NP)(IO)(NW)

Creating a file from an administrator PowerShell session works fine.

  • Can you add the result of icacls X: to your question, where X is your drive letter? Have you tried an elevated command prompt?

  • the permission seem OK, and even if they weren't you should get an Access Denied (0x5) not a 0x80070522. Can you create a directory in the root as normal or elevated user?

  • @PeterHahndorf I can create a directory as a normal user no problem.

  • I would ignore that error and store all my files in directories under the root. Storing files on the root level is never a great idea.

Have you tried disabling UAC? Same thing happened on my Workstation, and now it is working great.

  • Start/Run/secpol.msc
  • Local Policies
  • Security Options
  • User Account Control: Run all admins in admin approval mode and Right Click
  • Click properties
  • Check disabled
  • Reboot Computer/PC.

  • Yes. Unfortunately, it didn't help.

I just tried this on a more recent build (10586), and the problem seems fixed. :)

  • I'm currently experiencing the same problem on build 17763, so not sure this was ever fixed. You may have gotten lucky.
