Question: HyperV instance running Windows 10 & built-in VPN, I would like to prevent all internet traffic in the instance that the VPN fails. This answer provides good information:

[In Windows 10 how do you ensure all traffic goes through VPN?](https://superuser.com/questions/1021371/in-windows-10-how-do-you-ensure-all-traffic-goes-through-vpn/1021384#1021384)

But I get the error:

The route deletion failed: Element not found

Can something like this process be performed on a HyperV instance?

Answer: 
just change the extension of the file to .RAR and expand it. It should uncompress the file without any problem.
This error usually happens when a compression operation of a large folder is interrupted.
The issue for me was that I had zipped the files at a **relative** location with double dots i.e. I'd run `zip -r zipfile_name.zip ../relative/path/to/folder`. Recreating the zip but using an absolute path solved my problem e.g. `zip -r zipfile_name.zip /absolute/path/to/the/same/folder`.
