pass ok

What did you see instead?

not ok

This issue is related on #23153. This test fail to match name of interface since wmic command output DBCS (double byte character set) when redirect to pipe. But wmic command output utf-16 when redirect to file. So the test should fix to get output from file.

Thank you for creating the issue. Please provide the output of the error message. Maybe provide a screen shot?

I will let @johnsonj decide what to about his CL 84696 before we deal with this issue.

I believe this is fixed, in that the test no longer fails because it is no longer run.
