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."
Why this matters: 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.
Personalization priorities
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.
Users can now unpin the Cortana menu in the Microsoft Edge browser, as well as the Favorites pane and Reading pane, too. Just look for the little pin icon to the upper right.
A new look for icons, others
A more controversial update may be the new icons that Microsoft has added to Windows 10. As you can see in the collection shown below, they mix older and newer visual styles. "In earlier preview builds, we heard our design was too flat and lacked richness," Aul wrote. "We've since iterated to deliver a balance between mono line style icons on mobile, and the three dimensional depth of desktop icons. The new icon set is familiar, yet fresh and usable."
Don't expect things to remain the same, though--Microsoft plans to iterate new icons even as it tweaks other features.
Likewise, Microsoft also tweaked the new "jump lists" on the taskbar, which explode out with options when you click on them.
Finally, there's the new Cortana button: the WIN key + C. Microsoft positioned this as an option for keyboard users, and that's plausible. It might also be an option for those who lack modern PC hardware and an active mic--or an acknowledgement that the "Hey Cortana" active-listening feature needs some tweaking.
Other improvements include allowing movies to be played back in the Movies & TV app in full screen, as well as a new Print to PDF function.
Are there bugs Sure. Wi-Fi connectivity issues have been reported, Aul wrote, and may require a restart. The Mail app may crash and not sync mail properly. Aul also said that the recent Build 10122 won't be pushed to the Slow ring, due to a bug (which I experienced) that gave some users fits when trying to upgrade to the new build.
In all, however, Windows 10 continues to become more refined. Aul said the company is still on track for a summer launch, which is looking more and more like July.
