Introduction
Windows 11 officially started rolling out this week. Before installing the new operating system, you can check out all of its known issues. A recently updated doc from Microsoft lists the known issues with Windows 11. Note that since Windows 11 just launched, more issues could be discovered.
At the moment, the only known issues are related to compatibility. Here are all of the known issues currently listed by Microsoft:
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.
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.
Compatibility issues have been found between browser and Windows 11
Compatibility issues have been found between browser and Windows 11. The browser might be unable to open and, on some devices, might cause other issues or errors.
