- The June 2025 Update for Windows 10 rolls out as a preview in the Release Preview Channel.
- It rolls back seconds to the clock and events for the Calendar flyout and introduces various fixes.
UPDATED 5/29/2025: Windows 10 update KB5058481 (build 19045.5917) is now rolling out in the Release Preview Channel as the first preview for the June 2025 update. This is yet another maintenance update for Windows 10 22H2, which introduces a new Calendar feature and various non-security fixes.
According to the official changes (Release Preview Channel previous notes), Windows 10 build 19045.5917 introduces a couple of non-security fixes for GB18030 and GB18030-2022 characters and an issue causing high server load on the Windows Account Sync Consent system in European Economic Area markets.
Although the operating system is now in maintenance mode, Microsoft continues to roll out new features. In this release, Windows 10 updates the Calendar flyout to bring back the clock view that displays seconds. Also, the flyout will now show upcoming events for the next 30 days, and it adds new text for the weather button in the Calendar.
Microsoft did not define updates in the Release Preview Channel. When the updates are ready for the Stable Channel as a preview, it’ll be known as a non-security update, and it’s not until they become fully available during the Patch Tuesday Update release that the company will label them as the “June 2025 Security Update.”
Installation process
To download and install this quality update for Windows 11, open the “Windows Update” settings, turn on the “Get the latest updates as soon as they’re available” option, and click the “Check for Updates” button. It’s important to note that it may take some time until you see the new features and changes on your computer as Microsoft gradually rolls out improvements.
Windows 10 end of support
Microsoft announced the end of support for Windows 10 on October 14, 2025, even though they are still releasing maintenance updates. After this date, Microsoft will no longer provide security updates, bug fixes, features, or technical support for Windows 10. This lack of updates will leave your system vulnerable to security threats and may decrease its performance.
Since the software giant will no longer provide updates or support for Windows 10, you should upgrade to Windows 11 or another operating system, such as Linux Mint, or plan to purchase a new device.
If you want to continue using Windows 10, Microsoft now offers Extended Security Updates (ESU). This service was originally reserved for organizations needing to run older operating systems beyond the official support period, but it is now also offered to regular consumers.
