Windows 11 is now available, and with the launch of the operating system, the initial known issues have been documented, including a problem with Intel networking hardware.
The biggest problem on Microsoft’s status page for Windows 11 listing known issues is compatibility problems with Intel Killer network drivers.
Microsoft explains: “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.”
So, you may see a slowdown with your internet connection on a device that uses Intel Killer hardware, flakiness with streaming content as noted, or indeed sluggishness with VPNs using the OpenVPN protocol (which runs with either UDP or TCP, the former mentioned option being the one used for speed as opposed to reliability – but it won’t be speedy for affected users, of course).
Microsoft is working on the problem and anticipates delivering a cure in its October cumulative update for Windows 11 which will be out in a week (October 12).
Two further compatibility problems are listed here, the first being issues with Oracle VirtualBox which can scupper the ability to fire up VMs (Virtual Machines) in Windows 11 (errors may also be encountered). For this one, Microsoft says that Oracle is planning on updating VirtualBox to fix the gremlins at some point in October.
The final problem isn’t one the vast majority of users will ever see, as it’s with a Vietnamese Chromium-based browser (‘Cốc Cốc’) which may not work properly (or indeed open at all) under Windows 11. There’s no info on when this one might be resolved; Microsoft simply says it’s investigating the issue (doubtless on a lower priority than the other bugbears).
Memory fail
As for unofficial issues, PC Gamer points out a memory leak issue which is impacting some Windows 11 users going by an extensive thread on Reddit. What’s happening here is that at least some folks – and there are plenty of confirmed reports of this, including PC gamer itself – are finding that when they close an instance of File Explorer, it isn’t releasing the RAM it used.
So, if you start opening up a lot of folders, one after the other, the resources they’re sapping on your PC are still tied up even after each folder is closed, eventually leading to a situation where a sizeable chunk of memory is blocked off, and the system starts running more sluggishly as a result.
The only solution, or rather workaround, is to restart File Explorer (in the Task Manager, you’ll find Windows Explorer listed as a process, and if you click on it, there’s a ‘Restart’ button bottom-right), or just reboot your PC. Incidentally, it’s here in the Task Manager where you can see how much memory that File Explorer is consuming.
Microsoft hasn’t acknowledged this purported bug yet, but hopefully is investigating it.

Analysis: Wait before leaping on the Windows 11 bandwagon
With Windows 11 literally only just having being released, teething problems are to be expected. As we know, with any big feature update to a desktop OS, there are going to be gremlins in the works, and that’s likely to be even more true when it comes to an entirely new version of Windows.
In fact, the official list of known issues is surprisingly tame, and realistically, only the Intel networking issue is going to affect more than a small number of folks, at least when it comes to the general computing public. However, the unofficial bugbear in the form of the memory leak is more worrying.
At any rate, Windows 11 will initially have a very limited rollout to users, just to test the waters and make sure there are no truly show-stopping bugs (the memory leak, if widespread, is pushing towards that territory, mind). In other words, it may be quite some time before Windows Update will let you know that the OS upgrade is ready for your PC.
While you can go ahead and manually install Windows 11 anyway, regardless of Microsoft’s automated rollout, it may not be a good idea to leap at the opportunity straight away.
There may be other issues like the memory leak one discussed above, or you could run into bigger problems still. It’s likely not worth the risk, overall, and we’d advise waiting at least a little while to install, and to see how things pan out with early adopters, unless you’re actually offered Windows 11 by Windows Update (and even then, for us, caution would be the better part of valor for a time yet).
