Failed to create virtual ethernet switch.
The system cannot find the file specified. (0x80070002)
Here is a to screenshot of error:
OS: Windows 8.1 (x64) + Update 1
Getting the same error when trying to create from Powershell.
Go to Settings -> Network & Internet
Select Change adapter options
Right click on NIC Adapter -> Properties
Reinstall the Hyper-V Extensible Virtual Switch

All resolutions suggested failed!
This did work immediately and I have had no issues since. Here is how you do it:
Open the following registry key and give "All Applications" full control permissions
That was it, no more issues after that.
