The Windows 10 update KB5053643 (build 19045.5674) is now rolling out in the Release Preview Channel as the first preview of the April 2025 update. This is another maintenance update for the operating system that brings various fixes and improvements to version 22H2.
According to the official changes, the Windows 10 build 19045.5674 introduces web search providers for Windows Search to comply with the European Economic Area (EEA) regulation.
Microsoft is also adding the Noto CJK (Chinese, Japanese, and Korean) fonts and updating Country and Operator Settings Asset (COSA) profiles. Also, to reduce the risk of unauthorized access, it enables system processes to store temporary files in a secure directory C:\Windows\SystemTemp by either calling the GetTempPath2 API or using .NET’s GetTempPath API.
The update KB5053643 also fixes thumbnail issues with File Explorer, Troubleshooters while in Remote Desktop, and incorrect text for printer using Independent Hardware Vendor (IHV) drivers.
Installation process
If you want to download and install Windows 10 build 19045.5674, you can force the update from Settings > Update & Security > Windows Update, turn on the “Get the latest updates as soon as they’re available” toggle switch and click the “Check for updates” button after enrolling in the Release Preview Channel from the “Windows Insider Program” page.
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.
The company also confirmed they will retire support for Microsoft 365 apps on Windows 10. While you can still launch and use apps like Word, Excel, and PowerPoint, Microsoft will no longer update them, which will likely degrade their performance and reliability.
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.
