Microsoft has confirmed a known issue causing the text on the “News and Interests”” Windows Taskbar to get blurry after installing recent Windows 10 updates. Microsoft is currently working on fixing this issue with a resolution to be provided in a future Windows release. Microsoft first started rolling out the Google Discover-like news recommendation feature to Windows 10 Insiders in the Dev Channel in January. The news feed feature was later backported to Windows 20H2 and 21H1 via preview releases issued to the Beta and Release Preview rings.”
