Microsoft begins the process of rolling out the next generation of its Windows operating system in different regions across the globe. As promised, the Windows 11 initial release phase commences in earnest. The Redmond tech giant previously claimed that Windows 10 is going to mark the final OS from the company. However, technological improvements oftentimes force the change of course midway. With the global launch now underway, users can make use of Windows Update for automatic updates or grab the ISO files to perform a clean installation.
Besides Windows Update, alternative methods to upgrade include Media Creation Tool and Update Assistant. There is no shortage of viable options when it comes to Windows 11 install as long as your device meets the minimum system requirements.
With that said, Microsoft is also advising users beforehand concerning known issues that could “Officially” impact Windows 11 version 21H2 on some devices. Users intending to install Windows 11 will probably encounter one or more of the following three known issues. So make sure to learn about the issues before proceeding with the update as they may appear more frequently after the widespread adoption of the operating system in the coming weeks and months.
Windows 11 21H2 Know Issues:
1- Compatibility issues have been found between Oracle VirtualBox and Windows 11
Microsoft and Oracle have found a compatibility issue between VirtualBox and Windows 11, when Hyper-V or Windows Hypervisor is installed. You might be unable to start Virtual machines (VMs) and you might receive an error.
To safeguard your upgrade experience, we have applied a compatibility hold on these devices from installing or being offered Windows 11.
Workaround: To mitigate the safeguard, you will need to remove Hyper-V or Windows Hypervisor until this issue is resolved with an update Oracle plans to release in October 2021. You can check Oracle’s progress by monitoring their ticket #20536. If you are no longer using VirtualBox, uninstalling it should also mitigate the safeguard. Please note, if there are no other safeguards that affect your device, it can take up to 48 hours before the upgrade to Windows 11 is offered.
2- Compatibility issues with Intel “Killer” networking software and Windows 11
Compatibility issues have been found between some Intel “Killer” networking software and Windows 11. Devices with the affected software might drop User Datagram Protocol (UDP) packets under certain conditions. This creates performance and other problems for protocols based on UDP. For example, some websites might load slower than others in affected devices, with videos streaming slower in certain resolutions. VPN solutions based on UDP might also be slower.
Next steps: Microsoft is working on a resolution and targeting its release in the October security update (October 12, 2021).
3- Compatibility issues have been found between Cốc Cốc browser and Windows 11
Compatibility issues have been found between Cốc Cốc browser and Windows 11. Cốc Cốc browser might be unable to open and, on some devices, might cause other issues or errors.
To safeguard your upgrade experience, we have applied a compatibility hold on these devices from installing or being offered Windows 11. If your organization is using Update Compliance, the safeguard ID is 35891494.
Next steps: We are presently investigating and will provide an update when more information is available.
Microsoft is suggesting to refrain from manually upgrading using the Update button or the Media Creation Tool until the resolution of these issues.
