Microsoft has quietly restored a pair of long‑requested taskbar behaviors to Windows 11 — the Notification Center (and calendar flyout) can now be opened from a secondary display on multi‑monitor setups, and the larger calendar clock with seconds has returned to the Notification Center — delivered as part of the optional preview update KB5065789 for Windows 11 versions 24H2 and 25H2.
For years, Windows power users have lived with a jarring inconsistency: on multi‑monitor systems the taskbar on secondary displays showed the time and date, but clicking them did not open the Notification Center or calendar flyout. That interactivity was only available on the primary display, forcing users with desks full of monitors to move the cursor across screens to check notifications or glance at a larger calendar clock. Windows 10 had the more intuitive behavior; when Windows 11 first shipped, Microsoft’s redesigned taskbar removed or altered several small but useful features — and multi‑monitor notification access was one of the most frequently mentioned omissions.
Microsoft’s recent preview update, KB5065789 (released as a non‑security preview on September 29, 2025, and staged for inclusion in the October patch cycle), reunites Windows 11 with these elements. The update is published for both the 24H2 and 25H2 branches, reflecting Microsoft’s shared codebase between those two servicing channels. Microsoft’s support notes document KB5065789 as a preview that includes a broad set of quality fixes and feature roll‑outs delivered in a gradual fashion.
The release also exposes the tradeoffs Microsoft faces: balancing a stable, unified design language with the need for configurability and power‑user preferences. The company’s current strategy — release a reimagined design, then selectively restore high‑value legacy affordances — appears to be the path forward. For end users, these changes are welcome and demonstrate Microsoft continues to iterate thoughtfully on the Windows 11 experience.

Background
For years, Windows power users have lived with a jarring inconsistency: on multi‑monitor systems the taskbar on secondary displays showed the time and date, but clicking them did not open the Notification Center or calendar flyout. That interactivity was only available on the primary display, forcing users with desks full of monitors to move the cursor across screens to check notifications or glance at a larger calendar clock. Windows 10 had the more intuitive behavior; when Windows 11 first shipped, Microsoft’s redesigned taskbar removed or altered several small but useful features — and multi‑monitor notification access was one of the most frequently mentioned omissions. Microsoft’s recent preview update, KB5065789 (released as a non‑security preview on September 29, 2025, and staged for inclusion in the October patch cycle), reunites Windows 11 with these elements. The update is published for both the 24H2 and 25H2 branches, reflecting Microsoft’s shared codebase between those two servicing channels. Microsoft’s support notes document KB5065789 as a preview that includes a broad set of quality fixes and feature roll‑outs delivered in a gradual fashion.
What changed in KB5065789
Notification Center and calendar flyouts on secondary displays
One of the most visible changes is functional parity for the system tray across multiple monitors: clicking the date/time area on a secondary display now opens the Notification Center and calendar flyout — the same behavior users already had on the primary display. This is a user‑experience fix more than a technical overhaul, but its impact on productivity for people using two or more monitors is immediate. Tech press coverage and early Insider reporting confirm the change landed in Dev/Beta preview builds and has been folded into the preview KB for general testing.Calendar flyout clock with seconds
Windows 11 now offers the larger calendar flyout clock that was absent from early Windows 11 builds. The flyout can show a larger clock display with seconds — a feature many longed for after the Windows 11 taskbar initially removed several Windows 10 conveniences. The clock is off by default and is controlled by a new toggle in Settings: Settings > Time & language > Date & time > Show time in Notification Center. When turned on, the calendar flyout displays the time (including seconds) above the date and calendar grid. Several Windows how‑to sites and Insider reports document the new setting and how to enable it.Delivery channel and rollout model
KB5065789 is a non‑security preview (C/D‑release) update that Microsoft published on September 29, 2025. Microsoft uses a staged rollout model: the preview is available as an optional install (visible when users enable “Get the latest updates as soon as they are available”), and fixes and features may be gradually enabled via A/B testing or server‑side feature flags. Microsoft’s documentation and Windows Insider notes emphasize this gradual activation model; consequently, even after installing KB5065789, some users may not see the change immediately. Microsoft plans to include the preview fixes in the October Patch Tuesday cumulative releases as well.How to get the features now — step‑by‑step
There are two paths: the supported route (install the preview update and opt in to early feature flights) and the power‑user route (use third‑party tooling to force‑enable features that are currently gated). The supported path is recommended for most users; the second route carries risk and should be used only by experienced users who understand the implications.- Supported (recommended) method
- Open Settings > Windows Update.
- Toggle on Get the latest updates as soon as they are available (this opt‑in exposes optional preview releases and feature flights).
- In Optional updates available, locate and install KB5065789 (September 29, 2025 preview / October patch preview).
- After installation and a reboot, open Settings > Time & language > Date & time and enable Show time in Notification Center if the option is present.
- Verify behavior on a secondary display by clicking the date/time area on the secondary taskbar. If the Notification Center or calendar flyout appears, the change is active.
- Power‑user (ViveTool) method — caution advised
- Some Insider and preview features are still hidden behind feature IDs used in Microsoft’s controlled rollouts. Community tools such as ViveTool (open source) can toggle these feature flags, but using them bypasses Microsoft’s controlled activation and may cause unexpected behavior.
- Commonly reported ViveTool usage to expose the Notification Center clock includes commands like:
- vivetool /enable /id:42651849
- (If the first ID doesn’t surface the feature, users have reported success with /id:48433719 as an additional toggle.)
- After enabling, restart explorer.exe or reboot, then check Settings > Date & time to toggle Show time in Notification Center.
- Important caveat: using ViveTool modifies hidden feature flags and is not supported by Microsoft; it can complicate troubleshooting or update rollbacks. Back up data and use a test device where possible.
Why this matters: practical and UX implications
- Multi‑monitor users win back a small but meaningful time‑saver: no more hunting for primary display focus when checking notifications or the calendar. For professionals using full‑screen apps, trading between screens, or working with reference screens, the restored behavior reduces friction and cursor travel time.
- The return of the calendar clock — particularly the option to show seconds — matters for roles that need precise timing (e.g., broadcasters, real‑time trading desks, time‑sensitive testing). Previously those users relied on third‑party tools or kept a separate clock utility pinned to the desktop.
- The change illustrates Microsoft’s incremental approach to restoring or reintroducing legacy behaviors where user feedback is strong. It’s a reminder that some UI design choices made at initial release were intentional but continue to be tunable based on cumulative feedback.
Enterprise and IT admin considerations
- KB5065789 is a preview (non‑security) update intended for testing and validation. Enterprises should not deploy optional preview updates en masse without proper QA, because preview packages can include experimental features or be tied to enabling server‑side flags that aren’t yet fully validated in corporate environments. Microsoft’s documentation explicitly marks these releases as preview and indicates that they roll into the formal Patch Tuesday cumulative releases. IT pros should treat KB5065789 as an optional test release and wait for the targeted Patch Tuesday build for broad deployment.
- The “Get the latest updates as soon as they are available” toggle can cause devices to receive out‑of‑band or experimental updates. For managed devices, administrators should avoid toggling this for production systems and instead validate changes in a test ring first.
- If enterprises depend on specific multi‑monitor behaviors or have custom tooling that interacts with the taskbar or Notification Center, testing is essential. Small UI changes can ripple into automation tools, remote‑control software, or custom shell extensions.
Risks, known issues, and cautions
- Preview updates are optional and sometimes buggy. Microsoft-run forums and Q&A threads show users encountering installation or post‑update issues with preview builds. If you’re not troubleshooting‑savvy, skip preview installs until the changes reach the regular cumulative update channel.
- Using ViveTool to force enable hidden features is a community technique, not an official Microsoft support path. ViveTool modifies internal feature flags and can complicate future updates or support calls. Use it only on test machines and understand how to undo changes (vivetool /disable /id:<ID> or a full reset).
- Feature rollout variability: even after installing KB5065789, the Notification Center clock or multi‑monitor behavior may still be disabled for your device because Microsoft activates features server‑side and ramps them gradually. Do not assume that installing the KB will immediately enable everything for all machines.
- Minor UI regressions or accessibility regressions could surface; Microsoft’s gradual approach intends to catch these, but early adopters may encounter stray issues. Testing with assistive technologies is recommended if devices are used by people with accessibility needs.
Alternatives and complementary tools
If the native options still don’t meet a user’s needs — or if they prefer more customization than Microsoft offers — there is a thriving ecosystem of taskbar and tray mods and utilities:- Windhawk mods: Windhawk hosts a popular Taskbar Clock Customization mod that can show custom formats, news, weather, and performance metrics like CPU and RAM in the clock area; it’s widely used by enthusiasts seeking deeper customization than Windows natively provides. Windhawk is a lightweight mod framework and its taskbar clock mod specifically lists features for news feeds, weather, and performance metrics. Users should evaluate the stability and review the mod’s source code before installing.
- HWiNFO, Core Temp, and similar utilities: these well‑established system‑monitoring tools can push sensor values (temperatures, loads) to the system tray. They’re a safer path to see CPU/GPU metrics in the tray without modifying Windows internals. HWiNFO supports adding sensor readings directly to the tray area.
- Rainmeter and third‑party skins: for users who want rich desktop displays with clocks, news, and telemetry, Rainmeter remains the go‑to. It provides powerful, networked widgets that can sit alongside the taskbar.
Technical notes and verification
- Microsoft’s support page for the September 29, 2025 preview documents KB5065789 as the optional non‑security release for Windows 11 versions 24H2 and 25H2, and lists the build numbers associated with the preview release. That page is the authoritative KB entry for the update.
- Independent reporting from outlet coverage and Windows Insider announcements documented the change in multi‑monitor Notification Center behavior in preview and early Beta/Dev builds prior to the KB’s publication, corroborating the timeline that the feature was tested in Insiders and then included in the preview KB.
- Multiple how‑to and technical blogs tested and published the specific Settings toggle name and guidance to enable the calendar flyout clock — commonly quoted as Show time in Notification Center under Settings > Time & language > Date & time. Those guides also reported the setting is off by default and that the feature is gated and may require opt‑in or a feature‑flag unlock on some devices.
- Community documentation and Insider posts verify the ViveTool IDs commonly quoted for earlier Insider builds (for example, id:42651849 and id:48433719 to expose the flyout clock). Note that feature IDs can change between builds and over time as Microsoft iterates — so these IDs should be treated as ephemeral and may not apply to every release. Proceed with caution and cross‑check latest Insider guides if using ViveTool.
Practical troubleshooting checklist
- If you installed KB5065789 but don’t see the feature:
- Confirm the KB actually installed (Settings > Windows Update > Update history).
- Ensure Get the latest updates as soon as they are available was toggled on prior to installing the preview; some preview content is gated to that opt‑in.
- Reboot after installation; some features require explorer.exe restart or a full reboot.
- If the setting is still missing, wait a few days — Microsoft’s feature rollouts are often controlled server‑side.
- For power users testing ViveTool, enable the commonly reported IDs, reboot, then check Settings > Date & time. If issues arise, disable the IDs or uninstall the preview and roll back to the last stable configuration.
The broader picture: product design, listening to feedback, and small UX wins
This tiny but visible reversal — returning a calendar flyout clock and restoring Notification Center access on secondary displays — is an instructive case study in product design and community feedback. Microsoft’s initial Windows 11 taskbar choices embraced a minimalist, curated approach, but the persistence of community demand for a few legacy behaviors shows that small affordances can have outsized practical value.The release also exposes the tradeoffs Microsoft faces: balancing a stable, unified design language with the need for configurability and power‑user preferences. The company’s current strategy — release a reimagined design, then selectively restore high‑value legacy affordances — appears to be the path forward. For end users, these changes are welcome and demonstrate Microsoft continues to iterate thoughtfully on the Windows 11 experience.
Conclusion
KB5065789’s reintroduction of secondary‑display Notification Center access and the calendar flyout clock is a small but meaningful restoration of lost functionality that directly benefits multi‑monitor users and anyone who values a quick, glanceable clock. The features are packaged in a preview update and will be rolled into the formal October Patch Tuesday servicing, but Microsoft’s gradual activation model means not every device will see the behavior instantly. For most users, the safest path is to install the preview only on test machines or wait for the cumulative release; advanced users may force visibility with ViveTool or choose mature third‑party mods such as Windhawk or sensor utilities like HWiNFO when they need deeper customization. This is an incremental, pragmatic win for Windows 11 usability — a reminder that sometimes the smallest features deliver the biggest daily benefits.Source: Neowin A long-requested taskbar feature finally makes it to Windows 11
