What you need to know

  • Windows 10 20H1 build 18936 is now available for Fast ring Insiders.
  • Along with the new build, Microsoft has opened up screen mirroring via the Your Phone app to more Surface devices.
  • This build also introduces password-less sign-in for Microsoft accounts on Windows 10.

Another week means there's a fresh Windows 10 20H1 Insider build to check out in the Fast ring. The latest build pushes the build number up to 18936 and includes the usual batch of bug fixes and improvements, but there are also some cool new features to check out.

Most notably, launching alongside this build is the rollout of support for Your Phone screen mirroring for more Surface devices. The feature is enabled through a driver update for Insiders on the following devices: Surface Laptop, Surface Laptop 2, Surface Pro 4, Surface Pro 5, Surface Pro 6, Surface Book, and Surface Book 2.

There's also a new password-less sign-in feature for Microsoft accounts and much more. Here's a look at all of what's new.

What's new in 18936

  • Your Phone app – Phone screen now available on more Surface devices: As promised, we're excited to expand the availability of the phone screen feature to more PCs. With the latest driver update in the Windows insider rings (Marvell 15.68.17013.110), the following Surface devices will preview the phone screen feature – Surface Laptop, Surface Laptop 2, Surface Pro 4, Surface Pro 5, Surface Pro 6, Surface Book, and Surface Book 2. If you have one of these devices, give it a try and let us know what you think!
  • Quick Event Create from the Taskbar: Do you ever open the clock and calendar flyout to help organize your thoughts while making plans? We've been working on making it easier to create new events and reminders, and are happy to announce that as of today, all Insiders in the Fast ring should see this when you click on the date in the taskbar:

  • Pick your desired date and start typing – you'll now see inline options to set a time and location. We're looking forward to you trying it out! Let us know if you have any feedback.
  • Go passwordless with Microsoft accounts on your device: For improved security and a more seamless sign-in experience, you can now enable passwordless sign-in for Microsoft accounts on your Windows 10 device by going to Settings > Accounts > Sign-in options, and selecting 'On' under 'Make your device passwordless'. Enabling passwordless sign in will switch all Microsoft accounts on your Windows 10 device to modern authentication with Windows Hello Face, Fingerprint, or PIN. Don't have Windows Hello set up yet? No problem! We'll walk you through the setup experience on your next sign-in. Curious how a Windows Hello PIN is more secure than a password? Please note: This feature is currently being rolled out to a small portion of Insiders and the above option may not show for all users in Settings. If the toggle isn't showing for you yet, check back in a week so.

Portable (and affordable) power accessories we love

Each and every one of these charging gadgets will keep your favorite gear and gadgets going for longer, and none of them costs more than $30.

VisionTek 8,000 mAh micro-USB power bank (opens in new tab) ($13 at Dell)

This compact dual-output powerbank can speedily recharge any and all your devices, thanks to a two-amp "fast charge feature," using its micro-USB out port. Its simple design includes an LED indicator, and it costs about as much as a single ticket to the movies.

Panasonic eneloop AA batteries (opens in new tab) (From $13 at Dell)

Panasonic's rechargeable batteries are among the best available, and just a couple of them will keep your favorite remote, mice or other peripherals powered up when you need them. They're also eco. And the company's affordable charger (opens in new tab) fits and charges both AA and AAA batteries at the same time.

Belkin Qi Wireless Charging Pad (opens in new tab) ($30 at Dell)

This unobtrusive Qi wireless charging pad looks good (and kind of like a UFO …) and easily charges all your Qi-compatible device up to 5W. Its LED indicator lights up when you're charging. And it costs just $30.

  • Windows 10 Insider Preview 18936.1000 (rs_prerelease) -Error 0xc0000005. Not even funny. Not able to update since 18890. They don't even try to fix the problem with i5 processors.
    Time for apple, Microsoft is getting worst every year.
  • Can't really complain about an Insider program you decided to join, especially the fast ring. MS discloses that there will be bugs that could make your computer inoperable. So, they suggest that you make a backup to system restore or ghost an image, if the error for some reason keeps you from doing this. It's even bee suggested to not join the Fast Ring with your main device, because of the issues that can potentially occur. I joined the Fast Ring, with my original Surface Pro. For the most part, the updates worked fine, with a few bugs, which was expected. However, I ended up getting an update that kept it from booting at all. I currently have the Pro 6, but I will not join the Fast Ring with this device. I will eventually get the old Surface fixed.
  • Yup, off to Apple for you. Clearly you have no idea what you're doing and have no idea what being on the "Insider" program means.
  • Never had an issue updating yet and My Surface pro runs an I5.
  • Have you tried using the latest ISO image to upgrade with? It might work better than Windows Update method. A clean install with the ISO would likely work too
  • try the last ISO
  • Interesting. I was under the impression my Pro 4 could not support Your Phone. Either they made some changes or they mislead me. Either way, I'm happy to see it. I will patiently wait for 20H1, since I refuse to go beyond the Slow Ring on my only computer.
  • I think virtually all computers are supported, but not all computers can use every feature, particularly the screen mirroring feature.
  • The person who wants to switch to Apple probably shouldn't be in the program but I share his frustration. I have been an insider in the fast ring for over four years and this is the worst it's been for getting a bug addressed. I am stuck on 18908 using a plain vanilla Surface Pro 2017 and yes it too is an i5. To see that the latest incarnation won't install is a little odd. I'm in the program to test the software. Obviously I can't do this for now. I suppose the real software engineers are off for the summer 😉. Maybe I'll be able to install again by September.
  • Well, I don't actuary like phone mirroring, I really want to see actionable notifications as you do on Dell Mobile Connect. That said, having dropped the money for a spec'd i7 SB1 not that long before the SB2 came out I was a bit aggrieved to not have it. This app has been getting better, notifications are a lot more reliable than they were and its working, I do look at my phone less now.
  • I prefer Dell connect, too. I really like being able to make and receive calls on my Surface.
  • I actually had a passwordless sign in tonight on my laptop which isn't in the Insider program. Usually my phone will pop an authenticator notification, but instead Windows popped up a PIN screen. Interesting.
  • How about inline stylus support and inline ink to text conversion for addding appointments and tasks for the day. Would be a very welcome addition as an input method to the systemtray clock and calendar widget, especially for all the surface tablet pc devices.
