This is how it worked for me: 4 - CPU cores 4 GB - RAM 30 GB - Windows 10 Pro OS Originally I only used 2 CPU cores and it worked fine, but the client got laggy even in low res mode. Also diskspace depends on what os your installing, but for bare windows 10 install it's around 25 GB.
I would recommend using google cloud, you can get a $300 credit for free. There is a thread with a guide. I used to spend $30/month of the credit for an instance that could handle 2 clients.
