The properties for this item are not availableThere’s a bug with Windows 10 which prevents you from seeing the properties for a folder.  To trigger it, you need to do the following:

  1. logon to Windows 10 with user account UserA.
  2. Run As an application, such as Explorer++ or QDir, with a different user account UserB
  3. right mouse-click on a folder, and select Properties.

“The properties for this item are not available” occurs.

The fix
Apply March 2016 Cumulative Update for Windows 10 for x64-based Systems (KB3140745), or later

The workaround
The “Interactive User” value needs to be removed form the the Runas registry key under [HKEY_LOCAL_MACHINE\SOFTWARE\Classes\AppID\{448aee3b-dc65-4af6-bf5f-dce86d62b6c7}]

You may need to take ownership of the key in order to change it.
