Microsoft has confirmed that this fall’s feature upgrade for
Windows 10 will be identical to the already-available May 2020
Update (version 2004).
If the typical upgrade scheduled is followed again, we’ll see
Windows 10 21H1 update in the Spring of 2021, but rumours
suggest that 21H1 won’t arrive until the second half of the
next year because
Microsoft has internally switched focus to Windows 10X.
Microsoft is currently testing builds from the Iron development
branch, and the Iron is the codename for Windows 10 21H1.
According to Microsoft, new features that you’ll see in preview
builds aren’t specifically tied to this release, so there is no
guarantee that these features will appear in the final version
of 21H1 update.
What’s new in Windows 10 version 21H1
Based on the changelog of development builds, here’s everything
you need to know about the update that will eventually become
Windows 10 will list unused files and apps you can remove
Windows 10 includes quick ways to free up space. For example,
the Storage Sense feature in Windows 10 allows you to delete
unnecessary and temporary files to optimize the storage when
the hard drive fills up.
You can also use the Disk Cleanup tool to reclaim space to
store more important files, but you may not notice the unused
apps, files or documents during the cleanup process.
With Windows 10 21H1 update, Microsoft has added a feature
called “User cleanup recommendations”. This feature, which is
currently part of the Storage settings, will create a list of
apps, files, personal data that you don’t use frequently.
You can sort the list by the date and easily decide if you need
large files, apps or not.
Offloading of apps
Windows 10 is also getting a new feature that will
allow you to offload apps that you don’t use frequently.
This feature will automatically archive your apps but your data
and settings will be saved. Once you try to reopen an app
that’s been archived, Windows will automatically download and
restore the app again from the Microsoft Store (if it’s
The ‘Archive’ apps feature is currently available in preview
builds and is expected to arrive with Windows 10 version 21H1.
One preview build, available in the Dev Channel, comes with a
more intuitive way of managing your computer’s disks and
With this feature update,
Microsoft is expected to modernize its Disk Management tool for
users. Unlike the classic Disk Management tool, this new
modern experience follows UWP principles and beginners can
easily view or understand disk information or create/format
For advanced users, Microsoft says it will continue to offer
the traditional ‘snap-in’ Disk Management MMC console.
Sound Device Settings
Microsoft is also improving the modern Sound Device Settings.
The Sound Device tab in the Settings app can now tell you which
sound device is your default player and you can also click on a
device to set it as default.
Likewise, Microsoft has updated the classic Volume Mixer with a
new link that opens the Settings app’s per-app sound screen.
Task Manager is getting a new column called “Architecture” that
will show you the architecture (x64, x86, xARM64) of each
Windows 10 now lets you configure the DNS directly from the
Settings app. This feature was previously accessible via the
DNS Over HTTPS
DNS over HTTPS (DoH) is designed to make your web browsing more
secure and private by blocking outsiders from discovering the
websites your computer is accessing.
Preview build adds a build-in DoH setting to Windows 10 that
will enable DNS over HTTPS for all apps and browsers
running on your PC. This includes Microsoft Edge, Chrome, and
Built-in DoH support is incredibly handy as you no longer need
to configure each browser’s DoH settings individually.
Apparently, Windows 10’s DoH feature is currently only
available to testers and is expected to be included in the next
year’s update. If you want access to the system-level DoH in
Windows 10 preview builds, simply head to the network settings
and configure the DNS.
