Getting certs into local machine databases should[1] be possible on all 
Windows certified machines, but in the status-quo there's no 
cross-vendor solution to doing this. Relying on the Shim-provided

[1] Every time someone has claimed it's impossible to me I've ended up 
demonstrating otherwise, but that's not a guarantee
