Microsoft's latest flight to the Beta Channel lands with a fresh accessibility tool and a long-awaited stability fix. Windows 11 Insider Preview Build 28020.2298, released on June 12, 2026, gives testers on the 26H1 branch an early look at a new Screen tint feature while patching up Task Scheduler's reliability gremlins.
This build is the first tangible sign of what the 26H1 feature update will deliver later this year. For now, it's light on new features—the Screen tint addition is the only headliner—but the quiet Task Scheduler tweak is just as important for anyone who relies on automated scripts and background tasks.
What's Included in Build 28020.2298
The build number 28020.2298 belongs to the 26H1 development branch, which will eventually become the feature update for the first half of 2026. It's being tested exclusively in the Beta Channel, meaning it's in a relatively stable state but not yet ready for the Release Preview ring.
Here's the official changelog as gleaned from the Insider blog and community reports:
- New accessibility setting: Screen tint. Found under Settings > Accessibility > Color filters, this option applies a customizable tint overlay across the entire display. You can adjust the hue, saturation, and intensity. A quick toggle keyboard shortcut (Windows key + Ctrl + C, then press repeatedly to cycle through filters) now includes Screen tint alongside the existing inverted, grayscale, and custom color filters.
- Task Scheduler reliability improvement. An issue causing Task Scheduler to lose its connection to the task engine after extended system uptime has been fixed. Scheduled tasks that previously failed to trigger or showed a "last run failed" error should now run consistently.
- General fixes. The build includes the usual assortment of under-the-hood tweaks—memory management optimizations, a patch for a race condition in explorer.exe that could cause File Explorer to hang when navigating OneDrive folders, and an update to the Windows Kernel to better handle modern hibernation scenarios.
A Closer Look at the Screen Tint Setting
Screen tint is not a brand-new concept. Third-party tools like f.lux and built-in features like Night light have long let users warm their displays. But Microsoft's new implementation is more granular and integrated at the system level, with potential benefits for a wider range of accessibility scenarios.
How It Works
Once enabled, Screen tint applies a uniform color overlay to the entire display, including all apps, the desktop, and even the lock screen. The overlay sits above all other content, similar to how color filters work today, but with a crucial difference: you can fine-tune the tint continuously.
- Open Settings > Accessibility > Color filters.
- Toggle on Color filters if not already enabled.
- Select Screen tint from the dropdown.
- A set of sliders appears: Tint color (hue circle), Intensity (0–100%), and Opacity (0–100%).
- You can also check a box to apply tint to full-screen apps (like games and video players) if desired.
The keyboard shortcut Win + Ctrl + C now cycles through all active filters, including Screen tint. Hold the keys and tap C repeatedly to switch; a small notification flyout shows the current filter name.
Why Screen Tint Matters
Night light reduces blue light to help with sleep, but it shifts the display orange on a schedule. Screen tint is infinitely adjustable and can be left on permanently or toggled on demand. This makes it useful for:
- Eye strain reduction. Users sensitive to bright whites can apply a subtle sepia or light green tint that reduces harsh contrast without distorting colors too much.
- Light sensitivity and migraines. Certain hues, like rose or light blue, have been reported to help mitigate migraine triggers and photophobia. By tuning the tint to a comfortable value, users can work longer without pain.
- ADHD and autism spectrum support. A stable, low-saturation overlay can reduce sensory overload from rapid color changes in apps and websites.
- Nighttime reading. Unlike Night light which disappears after sunrise, Screen tint can be your permanent "darkroom mode" for reading at any time.
Comparison with Existing Features
| Feature | Night light | Color filters (existing) | Screen tint (new) |
|---|---|---|---|
| Purpose | Reduce blue light at night | Help users with color blindness | Reduce eye strain, accommodate light sensitivity |
| Overlay style | Warm tint, scheduled | Predefined filters (grayscale, inverted, etc.) | Custom hue, intensity, opacity overlay |
| Customization | Color temperature slider | Limited to preset filters | Continuous hue and intensity controls |
| Scope | System-wide (some apps can bypass) | System-wide | System-wide (optional for full-screen apps) |
| Keyboard shortcut | None (scheduled or manual toggle) | Win+Ctrl+C | Win+Ctrl+C (cycles through) |
Screen tint effectively bridges the gap between the narrow scheduling of Night light and the rigid presets of color filters. Power users will also appreciate that the setting is exposed to Group Policy and MDM, so IT admins can deploy a company-wide tint profile if needed.
Task Scheduler Reliability Improvement
The other highlight in build 28020.2298 is a fix for a long-standing Task Scheduler bug that could cause scheduled tasks to report a "The task is currently running (0x41301)" status even after the process had ended, or simply fail to start. This would often happen after the system had been running for several days without a reboot.
The Problem
Under certain conditions, the Task Scheduler service (svchost.exe) would drop its RPC connection to the task engine. The service would remain in a "running" state, and the UI would show tasks as scheduled, but none would actually execute. The only reliable workaround was a reboot or manually restarting the Task Scheduler service—a chore for server-like systems that need to stay up for weeks.
What the Fix Addresses
The changelog notes that the service now implements a keepalive heartbeat between the scheduler UI/engine and the task hosting process. If the connection drops, it automatically re-establishes without user intervention. This is particularly welcome news for:
- Windows Server administrators who rely on Task Scheduler for maintenance scripts.
- Power users running custom wake-from-sleep tasks, backup routines, or automation via .bat and .ps1 scripts.
- Developers testing services that depend on precise task timing.
While the fix is small in description, its impact on reliability is significant. No more phantom "running" tasks that never complete.
How to Install and Test
If you're already a Windows Insider on the Beta Channel receiving 26H1 builds, the new update will arrive via Windows Update automatically. To check:
- Go to Settings > Windows Update.
- Click Check for updates.
- If build 28020.2298 is offered, download and install it.
Not yet an Insider? You can join the Beta Channel from Settings > Windows Update > Windows Insider Program after linking your Microsoft account. But be aware: the Beta Channel is still pre-release software. Daily driving a Beta build is not recommended for production machines.
If you're on the Dev Channel, this build is not yet available there. Microsoft will likely release a similar build to Dev Channel testers in the coming weeks, but for now it's a Beta exclusive.
Known Issues
No Insider build ships without a list of caveats. While the official blog post for 28020.2298 is light on details, early feedback from the Windows Insider community highlights a few rough edges:
- Screen tint may not apply to some UAC prompts. The Secured Desktop still renders with default colors. Microsoft is aware and says a fix is planned.
- Task Scheduler UI may briefly show an incorrect status. Right after installing the build, the task list might display "Task is currently running" for all tasks for a few seconds until the service fully initializes. This is cosmetic and resolves on its own.
- Live captions flicker. On devices with certain Intel GPUs, Live Captions may show a brief flicker when Screen tint is enabled. A driver workaround is in the works.
- The new build watermark. The desktop watermark "Windows 11 Insider Preview. Evaluation copy. Build 28020" is present and will be until 26H1 reaches general availability.
The Road to 26H1
Build 28020.2298 is one of the earliest builds in the 26H1 servicing pipeline. Microsoft's development cycle for Windows 11 follows a predictable rhythm: new features land in the Dev Channel first, then graduate to Beta, and finally to Release Preview before the public rollout.
That this build dropped directly to Beta suggests that the Screen tint feature has been stabilized internally and Microsoft wants broader testing before the 26H1 launch. Historically, Beta Channel builds were reserved for the "next" feature update, but with the recent merging of Dev and Beta channels for some branches, it's possible that 26H1 is being co-developed.
What else can we expect in 26H1? Based on the tempo of past updates, look for:
- Further refinements to the accessibility suite, possibly including cognitive load reduction features.
- More AI-powered tools, building on the Copilot integration introduced in 24H2.
- Improved cloud and enterprise management features.
- Continued polish of the File Explorer, taskbar, and system tray.
But for now, Screen tint is the star. It's a feature that might seem minor at first glance but could have a meaningful impact on how people use their PCs daily.
Feedback and Next Steps
Microsoft is urging Insiders to try Screen tint in real-world scenarios and provide feedback via the Feedback Hub (Win + F). The team is particularly interested in:
- Which hue and intensity settings feel most comfortable for extended reading.
- Any performance impact on games or GPU-accelerated apps.
- Requests for additional shortcuts or quick toggles.
As with any Insider build, your telemetry and feedback help shape the final release. So if you've ever wished for a way to tint your screen exactly the way you want, now's your chance to influence the feature.
Build 28020.2298 is available now. Install it, test the new Screen tint, and enjoy a more reliable Task Scheduler—your automated scripts will thank you.
Windows 11 Insider Preview Build 28020.2298 is available to Beta Channel testers enrolled in the 26H1 branch. Not all devices will receive the build immediately; rollouts are gradual.
