The new build of windows 10 allows you to virtualize on arm64

The development of Windows 10 19H2, the second 2020 update of the operating system, is ongoing. However, unlike what many of us expected, we are hardly seeing any news for this second update. Week after week Microsoft brings new compilations of this future version of Windows to users within an Insider program, updates full of bug fixes (and new bugs) that, little by little, are shaping the second update of the year for Windows 10.

Users enrolled in the Windows 10 Insider program can already test the new build 19559 of the operating system before anyone else . As usual for several weeks now, this new version brings a large number of bug fixes and a complete list of bugs yet to be corrected. However, on this occasion, Microsoft has taken the opportunity to launch a long-awaited feature for the operating system, especially for those users who use it on low-cost computers or devices with ARM64 processors .

Hyper-V is Microsoft’s hypervisor that allows us to virtualize operating systems on top of Windows itself. Thanks to it we can install another Windows or Linux on a virtual hard disk. And in addition, it is responsible for running WSL, the Linux subsystem for Windows.

Computers with Intel and AMD processors can easily use this hypervisor. However, those computers with ARM processors did not have access to it, until now. Starting with this build, Windows 10 Pro and Enterprise users with ARM64 processors will finally be able to seamlessly use Hyper-V. It is not available for the Home edition of Windows 10.

There is no data on the performance of this hypervisor on this architecture, nor on whether all the functions are available. But it is a first step towards full support. Something important considering the Surface Pro X.

Fixed bugs in Windows 10 build 19559

In addition to the support for Hyper-V in ARM64, Microsoft has taken advantage of the release of the new build to correct several known bugs in its operating system:

  • Fixed bugs on Japanese IME keyboards.
  • Fixed a bug that crashed the file explorer when opening folders with photos in HEIC or RAW.
  • Fixed a bug that would freeze the file browser when trying to delete photos in TIF format.
  • Fixed a bug that did not fit the pixel well when using the Win + arrows keyboard shortcuts to place the windows on the screen.
  • Fixed a bug in the event virus that caused it to close.
  • Fixed the “KMODE EXCEPTION NOT HANDLED” bug that affected some Insider users.

Errors yet to be fixed in Windows 10 20H2

This new build 19559 also brings a larger list of bugs and bugs yet to be fixed.

  • BattleEye is still not working properly.
  • Narrator and NVDA are not working properly.
  • Microsoft is investigating some bugs that cause the update to hang for no reason.
  • There are two errors that affect users when using Windows Update: 0x8007042b and 0xc1900101.
  • Some IME keyboards still malfunction in the latest Windows 10 Insider builds.
  • The privacy section has a broken icon.
  • Fixed a connection error when using WSL2.
  • Some devices do not suspend properly or go to sleep.
  • The clipboard history is giving problems. If it opens (Windows + V) and closes without pasting anything, it stops working until the PC is restarted.

At the moment we still have no news about Windows 10 20H1, the update of the operating system that will reach users around April of this year. We expect that many of the bugs fixed in these 20H2 builds will reach 20H1 through a cumulative update after their release, as this new version of Windows 10 20H1 is already RTM.
