Quick things I’ve been using lately in w10. I’ve been a windows game developer for 20+ years by day and a win audio producer by night for about the same time length. Windows 10 is by far the best version of Redmond’s long in the tooth os.
Multiple desktop support has become very robust.
Win + tab will bring up an environment overview that allows you to add as many virtual desktops as your machine will handle. I use these modally (one for dev, one for art, one for communication) and I can switch between them without my hands leaving the keyboard. I am a long term supporter of tiled windows mangers (I contributed to WMI on Linux back in the 90s) and win 10 is getting closer to the perfect dev environment for me.
PowerShell/Linux support.
This is still a bit green but they have gone all in. PowerShell had gone from an awkward .net scripting language front end to a good shell mimicking bash. On top of that their goal of running a virtual Linux machine has been more successful than I thought it would be. It’s still rough, and I don’t use the actual bash shell daily, but doing apt-get on my Windows box bright a smile to my face.
Visual studio python support
This has been a game changer for me. Being able to have multiple python environments for all the different DCCs we use and building python modules aimed at each had been historically hard on Windows, and again in the last year or two things have turned around. Plus I hear the free version of visual studio is actually really good.
