Looks as a symlink on Windows 8 can has the FILE_ATTRIBUTE_DIRECTORY flag.

Create broken link:
 os.symlink('non_existing_patch', 'broken_link', target_is_directory=True)
What return os.path.isdir('broken_link')?

It returns True.

Then tests should be adapted for Windows 8.

This behavior is not specific to just Windows 8. Symlinks to directories are treated as directories on Windows, in particular, they should be removed with RemoveDirectory, not DeleteFile.
Is there any reason this issue is still open?
