Known issues in Windows 11

So far, Windows 11 has only three known bugs listed in the official documentation.

• Compatibility issues between Oracle VirtualBox and Windows 11. Microsoft says users might be unable to start existing virtual machines. To bypass the problem, Microsoft recommends removing Hyper-V or Windows Hypervisor. Oracle plans to release an update somewhere this month to fix the bug. Alternatively, uninstall VirtualBox.
• Compatibility issues between Intel Killer networking software and Windows 11. You might get slower than expected Internet speeds when using Intel Killer software on Windows 11. There are no workarounds, but Microsoft promises to fix the problem in October 2021 cumulative updates.
• Compatibility issues between the Coc Coc browser and Windows 11. The browser might not start. Again, there are no workarounds as Microsoft investigates the problem.

It is also worth mentioning that you might face other issues or bugs that slipped under Microsoft’s radars. Moving to a newly released OS is always a risky process, which is why Microsoft does not rush Windows 11 as fast as possible for everyone. If you are willing to take a leap of faith, Microsoft offers three official tools to upgrade your computer or perform a clean install of Windows 11.
