I hope you realize that this, though it is just a technical detail, has an impact on how we can/cannot use certain things, for example administrative tools, on windows 10.
Steps to reproduce:
On Windows 10 (here: v1511)
1 start notepad elevated entering different credentials (via right click or via runas.exe)
2 use the open dialogue to navigate to c:
3 rightclick a folder and select properties. You'll see an error message on windows 10: "the properties for this item are not available"
Why is that?
