Microsoft Enables Hyper-V Support for Windows-on-ARM Devices

Microsoft is determined in its goal to move away from x86-64 dominance it had in the personal computer space for many decades. In the latest Windows 10 Insider Preview Build 19559, Microsoft has enabled Hyper-V support for ARM64 devices, such as Surface Pro X. Hyper-V is a Windows native hypervisor and it is Microsoft's virtualization technology that allows running other OSes on top of Windows. Being a low-overhead solution, it is more efficient than a virtual machine and allows for better performance of OS that is running on top of Windows.

With the Insider Preview Build 19559, Microsoft is enabling this feature on a Windows 10 Pro and Windows 10 Enterprise customers. It is important to note that by adding more features like this, Microsoft is expanding the software ecosystem of ARM64 devices, which should result in wider adoption of PCs like the Surface Pro X.

Anti-cheat Software Runs Amok Causing System Crashes in Windows 10 Insider Previews

In what is likely to cause some hand wringing or chuckles depending on upon your personality, Microsoft's Windows 10 Insider Preview Slow Ring (beta versions of the OS) has not seen a new release in months. This is due to a common Anti-cheat software running amok and causing GSODs (replacement for BSODs in preview builds). The problem itself has existed for a few months and needs to be fixed by the creators of the software as noted by Chief of the Windows Insider program, Dona Sarkar, on twitter. Apparently, this isn't something Microsoft can fix due to how the software itself functions. Essentially the unspecified anti-cheat software runs in kernel mode and tampers with various aspects of the OS that it is not supposed to tamper with. While it is possible, the software is using allowed hooks in order to function. It is also possible that in the process it is damaging kernel data structures and code. This situation is likely to stir up debate on how effective anti-cheat software is considering it seldom seems to stop determined cheaters and as of now is causing the OS crash and is proving to be a thorn in Microsoft's side.

Still, this has more ramifications than just some system crashes or a software company that needs to edit some code. It directly results in Microsoft having to delay Preview releases. Since these Slow Ring builds can't be tested or validated. Pair that with the fact Microsoft's testing of Windows 10 builds is already considered lackluster with many bugs and issues going unresolved and you end up with a rather grim situation. After all, it was only a few short months ago that the October 2018 update was released after suffering numerous problems and delays. If issues like that continue, it seems the April 2019 update could be delayed as well. To avoid this and to get something done, Microsoft will be pushing out a Slow Ring build to systems that do not have the offending anti-cheat software. Better late than never but you would have thought that this solution would have been implemented sooner.
