Windows 10X is not just yet another version of Windows 10. It
feels like a tablet OS mixed with phone features and the new OS
will supplement Windows 10, not replace it. The modular
operating system offers a lightweight experience but there are
potential performance penalties for virtualized sandboxed apps
and long-term users will grumble about it.
Win32, UWP and PWA-based apps run within their own Container on
Windows 10X to protect the OS from potential malware and
A Container is essentially a virtual machine with higher
integration, lower latency, access to more resources of the
machine, dedicated kernel, drivers, and registry.
Unlike a traditional virtual machine, Windows 10’s Container
offers greater overall performance and the whole thing shuts
down when you close Win32 apps to preserve battery.
Win32 Container adds support for legacy and new Win32 code.
Inside the Win32 Container, you’ll be able to run all your apps
including the system utilities, web browsers, and even old
While Win32 apps support is one of the most fascinating parts
of Windows 10X, it appears that Microsoft has run into new
problems, according to sources.
According to sources familiar with the development, Microsoft
is struggling with the performance of Win32 apps when
virtualized on 10X and compatibility levels are still not
Win32 apps in the container, which are allowed to have a
background presence within the Windows 10X operating system,
are unable to send a notification when they’re minimized.
There are many other performance-related issues with desktop
apps when they’re virtualized in the Container.
It’s worth noting that not all legacy apps have performed badly
when virtualized on 10X, but there are some apps struggling in
the container for basic features including screen sharing.
The apps which rely on system tray are no longer supported and
such apps will have to move elsewhere if Microsoft doesn’t
improve the Win32 Container. Likewise, you won’t be able to use
apps, add-ins or namespace extensions to modify File Explorer
Another limitation will prevent Win32 applications from
applying keyboard, mouse and window hooks (customization).
The good news is that Microsoft won’t release a half-baked
operating system like Windows RT or Windows 10 Mobile.
Microsoft has already delayed Windows 10X into 2021 and
Microsoft plans to improve container performance and deliver
the promised features for the new modern operating system.
Microsoft’s solution has a long way to go and the company is
trying to improve the container so normal users would accept
