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: 
Sounds like you either don't have read permission on the zip file itself or write permission on the directory that is is contained in, which is where unzip is trying to create the files extracted.
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`.
