Here are all of the known issues with Windows 11
After months of waiting, Windows 11 is finally here. Microsoft has started the roll-out of the latest version of its operating system to people whose computers make the grade, but if you were hoping for perfection you are going to be disappointed.
Despite all of the testing with beta and developer builds, Windows 11 is still shipping with a number of known issues. Microsoft has shared details of these so you can weigh up whether they will affect you and whether you would like to upgrade to Windows 11 now or wait until things improve.

- How to install Windows 11 on any computer, even those without TPM 2.0
- Most people neither know nor care about Windows 11
Thankfully, the list of known issues is very small. In fact, there are just three problems on the list, although this number is likely to increase as Windows 11 spreads to more computers and users start to report more issues.
The three issues affect Oracle VirtualBox, Intel "Killer" networking software, and Cốc Cốc browser. For most people, none of these are essential pieces of software, meaning that the impact of the known issues should be limited.
Over on the Windows 11 support site, Microsoft shares details of these three known issues:
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.
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 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.
In the case of VirtualBox, it is hoped that Oracle will release an update to the software later this month, although no firm details are currently available. Microsoft says that it is working on a fix for the Intel issue, and this should be made available on October 12 as part of the October security update.
In relation to Cốc Cốc browser, Microsoft says:
We are presently investigating and will provide an update when more information is available.
Note We recommend that you do not attempt to manually upgrade using the Update now button or the Media Creation Tool until this issue has been resolved.
