14 DAY TRIAL // Windows 11 is now available for download for production devices, but as said, the rollout takes place in stages because Microsoft wants to detect potential problems early and prevent them from hitting devices out there.
At this point, there are three known issues in Windows 11, all of them listed as compatibility problems between the operating system and various software.
For example, Microsoft says it’s aware of compatibility problems between Windows 11 and VirtualBox, the Intel Killer networking software, and Coc Coc browser.
In the case of Oracle’s VirtualBox, Microsoft says that one possible workaround is to just remove Hyper-V temporarily. Oracle has promised an update to land as soon as this month.
“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,” Microsoft says.
Don’t update to Windows 11 if a block is in place
The Intel Killer networking software has also caused an upgrade block for those who are supposed to get Windows 11, Microsoft says.
“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,” it says.
The company recommends against installing Windows 11 using other methods as long as an upgrade block is in place, as this could lead to various issues on your device.
