Windows 11 has brought some great new features and design
improvements to the operating system, but perhaps the best
change is one that didn’t get much fanfare – under the hood
Windows 11 comes with several important changes to the way the
operating system prioritizes apps and processes. Microsoft has
done a lot of work in memory management to favour the app
windows you have running in the foreground so they have enough
CPU and system resources allotted when you launch them.
For example, when you’ve several tabs open in Microsoft Edge
and you launch multiple instances of Word, PowerPoint or Excel,
these apps will launch without any lag. That’s because these
app processes are already running in the foreground and they’ve
access to more compute resources than inactive apps.
As a result, Windows 11’s overall experience should feel
responsive and fast, especially when launch multiple apps on a
“That’s seconds of time saved in this case. And the time
savings add up as you use the apps over the course of your day.
So it feels responsive and fast. Foreground prioritization is a
big part of that. And this same concept actually applies to the
Windows shell itself, the browser and your open tabs in Windows
11,” Microsoft’s VP Steve Dispensa from the Windows Management
For a better experience, Microsoft has also enabled sleeping
tabs in Edge by default. This could result in an average saving
of 32% for memory and 37% for CPU usage on Windows 11 and
older. These optimizations will also equate to longer battery
life, according to a Microsoft spokesperson.
Microsoft has also confirmed that Windows 11 will make devices
resume from sleep faster than before. To offer a mobile-like
always-on experience, Microsoft has optimized Windows 11 calls
to hardware components.
Microsoft has also enabled a new feature that would ensure
enough power is available for threads that really need it to
wake up your device from sleep instantly. On devices with
8th-gen processors and newer, you can expect an “almost
instantaneous” experience, similar to Windows on ARM always-on
Windows 11’s new design optimized for performance
Windows 11 is all about design improvements and it comes with a
new “design material” called Mica, which applies to apps like
File Explorer, Settings, and nearly all inbox apps.
For those unaware, Windows 11’s Mica effect updates the
background colour of the application with the desktop colour
and theme to distinguish between several open instances of
Thankfully, Microsoft has optimized Mica and rounded corners
for performance. In a Q&A,
Microsoft promised that “performance is a top priority” for the
new design language and these new materials don’t harm the
usability of the OS.
In fact, Mica is expected to be faster than Fluent Design
materials like Acrylic.
It’s worth noting Windows 11 is not going to be significantly
faster than Windows 10, but the overall experience is expected
to be slightly better. On devices with hybrid processors like
Intel’s Lakefield processor, performance gains from Windows 11
could be between 2 percent and 11 percent, according to early
