Microsoft continues to polish the scuff marks on Windows 10 with its latest Build 10130. The new build, released Friday for download via the Fast Ring of the Windows 10 Insider program, adds new icons, some default behaviors for virtual desktops and even a manual trigger for the Cortana virtual assistant. There are some more Start menu tweaks, too.

Microsoft hasn't yet committed to a release date for Windows 10, but it's expected in July. Assuming that's more or less true, there's little time left to add new features. “As I mentioned with the last build, from here onward you are going to see a lot of tuning, tweaking, stabilizing, and polishing which means fewer big feature changes from build to build,” Gabe Aul, who oversees the Insider program, said in a blog post. “You’ll see that in this build which has a number of small improvements and more polish.”

Microsoft is well into the “tweaking” stage of Windows 10. Some features still need to be refined, such as the Edge browser, but some of the work now centers around allowing users to configure and personalize their experiences. This helps Insiders settle in to their Windows 10 preview builds, and also lets everyone begin to see what the final look and feel of Windows 10 will be.

As we began to see with Windows 8.1, Microsoft is providing more and more configuration options for the Start menu. As before, the new Start Menu in Windows 10 combines the Live Tiles and menu options of both Windows 8 and Windows 7. What the Start menu offers now are the choice to turn off and on app suggestions, recently opened apps, and even to jump right to the full-page Start menu at launch.

Likewise, Microsoft has declared a winner in the layout for virtual desktops, which group windows and apps in standard layouts that can be switched out. The debate concerned which apps were shown in the taskbar below: every app running on the machine, or just those within the desktop itself. The latter, “filtered taskbar” won out, and is now the default behavior—but fans of the alternative can change it via the Settings app > System > Multitasking > Virtual Desktops.

You’ll also find that the app menus have returned to the tablet mode of Continuum. That particular feature was demanded by Insiders, Aul said.
