Since the latest KB5021866 update, ExplorerPatcher is not anymore compatible.
Worse: it breaks Windows expected behavior.
There is no more taskbar and the process "explorer.exe" becomes buggy.
This is exactly why I do not want to edit the registry or use a third-party add-on program. A Microsoft update could disable the "fix" or, as PhunkyBob says, cause even bigger problems. Does anyone know when Microsoft will restore this "never combine" capability natively within Win 11? I would like to update to 11, but if my different Outlook windows (email, contacts, calendar, tasks) are all lumped together as one icon on the taskbar, the inefficiency of constant switching back-and-forth is a dealbreaker for me.
