Please let us know what your findings are as I'm having the same issue with SQL Server 2012 and 2014. The temporary netsh fix works at the moment.

ok so I just figured out my issue...

I found 2 'Shell' folders...

\AppData\Roaming\Microsoft\Microsoft SQL Server\100\Tools

\AppData\Local\Microsoft\Microsoft SQL Server\100\Tools\Shell

I had to remove both before it reset itself.

I'm having the same issue, I exported from SQL 2005 and also tried from a side by side 2005/2008 import and each time I tried to import the registered servers...
