+It seems like virtualisation technology has caught up on this topic. Current versions of VMware and VirtualBox should run just fine on Windows systems with Hyper-V enabled. This is documented in the FAQ of WSL (Windows Subsystem for Linux). I can verify this running 64-bit Windows and Linux guests in VMware 15.5.6 at the same time as a 64-bit Android system in the Android emulator that comes with Visual Studio and .NET MAUI. On Windows 10 22H2. Even on an Intel Core i7-3770 processor, one generation older than VMware’s original minimum requirements. So this tool is now probably obsolete for most users.

 Hyper-V is Microsoft’s virtualisation solution that can be installed with Windows. Visual Studio device emulators for Windows 10 Mobile rely on Hyper-V for the guest system. While this may work in most cases, it has the major disadvantage that Hyper-V is running permanently when installed, unlike application hypervisors like VMware or VirtualBox. With the Hyper-V hypervisor already running, these other virtualisation solutions cannot work properly, for example 64-bit support is no longer available and performance is degraded because the VT-x CPU hardware extensions are not available inside a VM guest (which your entire Windows desktop will then be). When using device emulators for Android or other VM solutions for other work, Hyper-V interferes badly with those virtualisation applications.
 
 The only option that Microsoft allows is uninstalling the Hyper-V role from Windows. This takes a short time and then restarts the system. It is also a bit hidden within the classic control panel in a lenghty list of features. When installing it again, you need to know which features to select.
