I had varying degrees of success and problems installing Discourse on my Windows 10.
What - knock wood - has worked best so far is to
- install a virtual machine (currently I’m using VMware)
- create a guest using Ubuntu as the server
- follow the “howto vagrant ubuntu” instructions
I am far from being a sys op and any success I ever have tends to feel more because of luck than actual knowledge. But installing into Windows 10 was a lot more hassle for me than installing into Ubuntu
