1. Windows 11: Focus Assist Mode - How It Works
Windows 11 has introduced new features that help you focus on what’s
important to you. One of these new features is Focus Assist mode,
which automatically lets you concentrate on your work without being
distracted by notifications and apps trying to get your attention. This
guide will show you how Focus Assist mode works in Windows 11 and
how to use it to stay focused while keeping distractions at bay.
What Is Focus Assist?

2. If you’re like most people, you don’t want to be interrupted while
working on a project. At least, that’s true until someone needs your
help or asks for a status update. Whether you're in a meeting or just
don't want to be disturbed, Windows 10 has a new feature called Focus
Assist that's designed to keep your focus and increase productivity.
Here's how it works and how you can make it work for you.
The 3 Modes In Focus Assist
Windows 10 has a feature called Focus Assist. This is a new feature
that, when enabled, helps ensure you aren't distracted while working.
By focusing on one application at a time, it keeps you from being
distracted by notifications from other apps and pop-ups. Here's what
each mode does: Block all notifications: When in Focus assist mode
with ALL notifications blocked, Windows limits sounds to reminder
alarms. You can still see what's happening with Action Center (if there
are new notifications) so that you won't miss any important alerts
about meetings or upcoming events in your calendar.
Turning On & Off
What You Can Do With Windows Focus Assist Mode: Windows' new
focus assist mode will provide users with a way to block notifications
while they're working on something else. This is just one of several new
features coming in the next version of Windows 10, and it's one that
might actually prove useful for students who spend a lot of time with
their laptops open in class, or for people who regularly need to focus on
just one task. Here's how you can enable it and use it.

3. Quick Task Switcher (Alt+Tab)
Switching between tasks can also be quite distracting, especially when
you have a dozen windows open. That’s why Windows has a feature
called Quick Task Switcher (called Alt+Tab). What it does is allow you to
quickly change between your open applications using only your
keyboard. Just hit Alt+Tab, and then use your arrow keys to switch
between apps. Note that if you want to use focus assist mode while
working in one application, then you should stop pressing tab or hitting
alt altogether. You will still receive notifications from other apps if they
are trying to get your attention, but you won’t lose focus as easily.
