I succeeded in shutting of News and Interests by following the recommendations for editing the registry:
- regedit in the search bar.
- Edit->Find in the Registry Editor
- search for 'ShellFeedsTaskbarViewMode
- double-click on the entry.
- change the 'Value data:' field from '0' to '2'
- click 'OK'
- File>Exitt in the Registry Editor
This worked for me, but with a modification:
ShellFeedsTaskbarViewMode won't allow a value change for some reason
ShellFeedsTaskbarPreviousViewMode does allow a change and appears to have solved the problem as days have passed with no more news junk popping up.
Hope I know what I'm doing and thanks for the tip.
