Microsoft just released Windows 10 Insider build 16237 for PC with a slew of new stuff, so we're breaking it down for you. Microsoft has made a number of Task Manager improvements for the upcoming Fall Creators Update, including the first appearance of a GPU tab in Task Manager that showed up in build 16226 (two builds ago). Today, that GPU performance tracker has undergone some tweaks, with an updated UI layout, more details like DirectX version, and the physical location of your hardware GPU. The blog post promises more improvements to come, as well.
Microsoft also released improvements to their Hyper-V virtual machine systems in this build, introducing a "virtual machine gallery" that's so far empty. The blog post again promises more details coming up, but the addition strongly hints at some ready made virtual machines coming to Windows, possibly similar to the way Azure handles a VM gallery.
What does work now is a "change installation source" button, that allows you to choose a local VM, either an .ISO or .vhd/vhdx file on your local machine, providing an easy and central way to install VMs.
