Microsoft has released the optional KB5058481 preview cumulative update for Windows 10 22H2, introducing seven notable changes with a focus on enhancing the calendar flyout experience.

## Key Changes in KB5058481

The most significant improvement restores seconds to the time display in the calendar flyout, a feature previously removed for some Windows 10 users. When clicking the time in the taskbar, users will now see the complete time including seconds, which can be valuable for specific tasks.

Additional enhancements include:

– Extended upcoming events period to 30 days in the Rich Calendar feature
– Added description text for the Weather button in Rich Calendar
– Fixed rendering issues with GB18030-2022 characters in plane 2
– Corrected width rendering of some GB18030 characters
– Updated Country and Operator Settings Asset (COSA) profiles
– Fixed Windows Account Sync Consent system issues in European Economic Area markets

## Installation Information

After installing this update, Windows 10 22H2 will be updated to build 19045.5917. Users can install this optional update by:

1. Going to Settings > Windows Update
2. Manually performing a “Check for Updates”
3. Clicking “Download and install” when prompted

Alternatively, users can manually download the update from the Microsoft Update Catalog.

## Known Issues

The only documented issue involves NOTO fonts appearing blurry or unclear when displayed at 96 DPI, particularly affecting Chinese, Japanese, and Korean text in Chromium-based browsers. Microsoft recommends setting display scaling to 125% or 150% as a temporary workaround.

As an optional non-security preview update, KB5058481 allows Windows administrators to test upcoming fixes and features before they’re included in the June Patch Tuesday release.
