Changes are coming to Windows 10 with the release of version 1903 that affect everyday users and IT decision makers. Here’s what you need to know.

Development of Windows 10 is a continuous process—while previous versions of Windows received service packs or point releases that served primarily as rollups of Windows Update security patches, Windows 10 receives feature updates on an approximately six month cadence. These updates bring significant user-facing changes, as well as changes to enterprise features.

Windows 10 version 1903 (also called 19H1) was made available to the Release Preview ring of the Windows Insider Program on April 8, 2019, and was added to the MSDN download catalog on April 18, 2019. General availability for consumers is expected in May 2019, though a firm release date has not been announced.

For those wishing to get an early look at the new version, check out TechRepublic’s guide to getting Windows 10 version 1903 early, likewise, those wishing to defer an upgrade should check out the guide to delaying installation of Windows 10 version 1903.

TechRepublic’s overview of the May 2019 update to Windows 10 is a “living guide” that will be updated as new articles about the update are published across TechRepublic, ZDNet, and CNET. For more on Windows 10 generally, also check out TechRepublic’s cheat sheet for Windows 10.

What to know before and after installing the Windows 10 May 2019 Update

Unplug and remove your external drives and memory cards

Users receiving notices that “This PC can’t be upgraded to Windows 10” when attempting to install the update should remove external drives and memory cards, as they can block systems from installing the update. The update process can cause drives—including internal drives—to be assigned different drive letters after installation.

You’ll need more free space to install the May 2019 update

Microsoft has increased the amount of free space needed to install the May 2019 update to 32 GB, an increase from the 16 GB needed for 32-bit versions and 20 GB for the 64-bit versions, which ZDNet’s Liam Tung called “entirely unrealistic.” Microsoft is also introducing “reserved storage,” allocating 7GB of the disk to ensure that future updates can be installed smoothly.

Check your privacy settings after installation

Previous updates to Windows 10 reset privacy settings to the defaults, which share a relatively high amount of usage and analytics data with Microsoft. Though Microsoft has attempted to be more transparent with privacy settings, the spontaneous reset of privacy settings can be an unwelcome surprise. Be sure to change your privacy settings in Windows 10 after updating.

The update brings more robust protections for Spectre and Meltdown

Microsoft is bringing Google’s retpoline patches to Windows 10, which should finally bring robust and performant patches for the Spectre and Meltdown vulnerabilities. Microsoft’s previous attempts at patching these vulnerabilities have been plagued with issues, as patches caused random reboots, blue screens, and inadvertently made it easier to exploit the vulnerabilities.

Forcing periodic password changes may become a thing of the past

Microsoft is questioning the wisdom of using Group Policy to enforce password expiration. The company is seeking public comment on the practice, arguing that the practice is outdated and ineffective. As TechRepublic’s Lance Whitney put it, “if you have evidence that [your] password had been stolen, you would change it immediately rather than wait for some predefined expiration date,” while Microsoft colorfully noted that “if your users are the kind who are willing to answer surveys in the parking lot that exchange a candy bar for their passwords, no password expiration policy will help you.”

New features coming to the Windows 10 May 2019 Update

Streamlining Start, Search, Accounts, and Sign-In

For new accounts, Windows 10 reduces the number of icons and groups applications into folders more than in previous versions, and makes them easier to remove. Likewise, there are now less hoops to jump through to uninstall built-in applications.

Search is now less cluttered, with filter icons at the top, the five most frequently used apps in the center, and recent documents and browsed pages at the bottom. Cortana has been separated from Search, now allowing people to remove the Cortana button from the taskbar.

The Sign-In options panel in Account Settings has also been streamlined, with an option to use a personal security (FIDO2) key added.

DPI Awareness includes better support for Hi-DPI apps & displays

As notebook computers increasingly use Hi-DPI displays, apps may not perform as expected when connecting external displays. Since Windows 10 Version 1803, Microsoft offers to fix apps without having to log out of Windows, so this fix is now applied automatically, unless the features is manually deactivated. It’s also possible to view and sort apps by DPI awareness in the Task Manager, as a column for that attribute has been added.

Other visual enhancements, including a “Light Mode” to complement the darker theme that shipped with Windows 10, were also added.

You can safely access Linux filesystem data inside File Explorer

Users of Windows Subsystem for Linux (WSL) will be able to access, move, and copy data stored inside WSL instances using File Explorer, making it easier for developers using WSL to manage files in those environments without relying solely on the command line, or third-party kludges that can lead to data loss or corruption.

Application sandboxing allows for safe app test driving

On Windows 10 Pro and Enterprise, Windows Sandbox adds a containerized environment for running untrusted executables. The sandbox is destroyed after the app is closed. This feature relies on hardware virtualization extensions (Intel VT-x, and equivalents) present on modern hardware, though this may require manually enabling these extensions in the system BIOS. Likewise, the Windows Sandbox feature itself must be enabled using the Windows Features dialog in the Control Panel.

Windows Defender System Guard brings advanced security features

The Windows Defender System Guard container, formerly called Virtualization-Based Security or Virtual Secure Mode, isolates the Windows kernel to shield against cases where it may be compromised. Using Hyper-V, secure “memory enclaves” are used to isolate signed code executed at a higher virtual trust level, preventing malware from editing firmware and boot components of Windows.

Likewise, Windows Defender Application Guard is a security mode for Microsoft Edge, which allows users to visit untrusted websites without worrying about malicious code on those websites gathering system information or downloading malware onto the computer. An extension exists for Chrome and Firefox that loads untrusted websites in the guarded Edge instance. It is unclear if or when this feature will support the new Chromium-based Edge, still under development.

Windows Admin Center modernizes Windows Server, Azure instances, and workstations

Improvements to Microsoft’s Windows Admin Center (WAC), following its introduction one year ago, allows system administrators to manage Windows Server 2019 instances, as well as Azure-hosted services, and traditional workstation deployments of Windows 10. The web-based WAC is particularly helpful for managing hybrid cloud deployments, as it unifies multiple services into one dashboard.

PowerShell access, naturally, is still available for users who prefer the command line. For users of Storage Migration Service or System Insights, WAC is the only GUI available. While not all functionality has been ported over from the classic Remote Server Administration Tools (RSAT), reliance on older tooling is only necessary in specific circumstances. TechRepublic’s Simon Bisson notes that “Microsoft is gently nudging admins and other users away from their old admin tooling,” adding that “it won’t be too long before it’s your only option if you want to get the most from your Windows Server installs.”

Features not coming to the Windows 10 May 2019 Update

With the Windows Insider early-access program, Windows development now happens far more out in the open than was the case with prior versions, leading to public-facing experiments that may not be adopted in final releases.

Plans for “Windows Sets” app data grouping abandoned

Sets, a Windows management feature that allows users to group app data, websites, and other information in tabs, appears to be abandoned in the update, according to ZDNet’s Mary Jo Foley, who noted that significant engineering work would be required of the Edge and Office teams to implement the feature, which was not well received in public testing with Windows Insiders. Users who want a feature like Sets can turn to the Stardock “Groupy” application, which provides similar functionality.
