I saw the same issue on my Windows 8.1 System: The link or junction was not visible to the cmd window and I was not able to delete it. I did the following to delete this junction:
- Launch Windows Explorer
- Navigate to "C:\Windows\System32\config\systemprofile\AppData\Local\Microsoft\Windows"
- In the Windows Explorers folder options enable (if not done already):
- Display the contents of system folders
- Show hidden files and folders
- Delete the folder/link/junction "INetCache"
