Windows 10 KB5003637 (Build 19043.1052) Full Changelog
- News and Interests feed is now enabled for everyone.
- News and Interests taskbar setting updated with new options.
- Fixes issues caused by News and Interests feed.
- Fixes memory leak bug.
- Fixes issues with Your Phone app.
Windows 10’s News and Interests feature was first announced in January and it started rolling out to consumers in April. With today’s update, Microsoft says it has enabled the feature for everyone.
For those unaware, the idea behind the new taskbar feed feature is to relevant information about what’s happening in the world by enabling Microsoft News (MSN) integration. In addition to MSN feed, News and Interests is also capable of showing local weather, finance widget, etc.
If it feels like another piece of bloat and you don’t want and wish it could go away, you can now easily customize the feed and turn off the “hover” feature or even disable the feed entirely.
To do improve News and Interests experience, you can open the taskbar menu (right-click anywhere on the blank area) and select the “Open on hover” option on the News and interests menu. This will turn off the hover effect.
Windows 10 Build 19043.1052 also improves the news and interests hover experience and it will no longer launch on its own.
In addition to News and Interests, Windows 10’s June update also addresses an issue that might prevent users from opening apps pinned to the taskbar using Microsoft Your Phone app.
As mentioned at the outset, Microsoft has fixed the memory leak issue in ctfmon.exe, a process used by Microsoft Office and some other apps with an editable box. In theory, this bug fix will help with high memory usage bug, but it depends on the configuration of the device.
Microsoft is currently not aware of any new issues in the update.
