I'm using Windows 10 tech preview.
Anytime I create a junction (using either mklink from cmd or junction.exe here: http://technet.microsoft.com/en-us/sysinternals/bb896768.aspx ), I cannot load it with Windows Explorer, nor does it work with any applications. I used this same technique in Windows 7 and Windows 8 with never an issue.
I get this error:
You don't currently have permission to access this folder. Click Continue to permanently get access to this folder.
Clicking Continue yields this error:
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 the only user, and an administrator. The security tab does not shed light -- SYSTEM, Administrators, and my user account all have full allow permissions on this folder. I have created multiple junctions and none seem to work.
