Hi all,

Windows released a new operating system - Namely Windows 11 (21H2).

We tested TeamViewer in the latest release and can confirm that all basic features work as expected, however - further tests are pending to announce full support of the new operating systems.

See Supported operating systems.

We´d like to collect your feedback about your experiences with TeamViewer on the new operating systems to speed up the process to announce full support.

Please share your feedback with us by commenting on this post.

To make sure that we understand your setup and findings, please share as many details as possible about it - of course without sharing any personal details.

Thanks for your help in making TeamViewer better and fully supporting the new Win 11 quickly.

Best,

Kerstin

Update (18th of October): Thanks a lot, to all of you who already tried out TeamViewer on Windows 11 and providing feedback. You´ve been incredibly helpful in the process of announcing full support. Thank you!

I am happy to inform you that now we have announced full support for TeamViewer 15.22 on Windows 11. 

Please see our Knowledge Hub article for more information on the details.

If there are more issues to report, we are still interested in further feedback, of course.

Thanks again for the collaborative teamwork from the whole R&D department here at TeamViewer.


Update (14th of October): With the Microsoft update from 12th of October the connections issues with UDP are solved at least for most users (as far as we know).


Update (7th of October): some users are having problems to set up a connection on Windows 11 machines. This is related to some specific network adapters. Please read my post for further details and a temporary solution.

    Tried using teamviewer yesterday with win 11, didnt work. Could login to remote PC's however often I was unable to type to login to windows on the remote pc, or the screen initializing once I had entered the initial TV password would just get stuck. Had to go back to win 10.

    Thanks a lot @daveabraham for the fast feedback! We double checked on our test machines but we cannot reproduce it.

    Do you maybe still have the log files that you could share with me (maybe in a private message. You can get them via top menu / Extras / Open log files.... Ideally local + remote side)?

    If someone else encounters a similar problem, please leave a comment and it would be great if you could save your log files before switching back to Win 10 and share them with us.

    Best,

    Hi, I have the log files of one of the remote PC's, but not from my laptop since I deleted and reinstalled on the win 11 machine before downgrading.

    Will send over on a private message.

    Hello, I am also having the same issues. Fresh install of Windows 11 and attempting to connect to PC's with both latest release of TeamViewer and TeamViewer QS resulted in the same results: successful connections followed by a frozen remote screen with nothing further. After multiple restarts and reinstallations of TeamViewer versions on both ends, I reluctantly reverted back to previous build of Windows 10 and all is well again. I have seen this in a few other forums in places such as Reddit and Twitter, and no success.

    Thank you, Michael

    Teamviewer does not work with Windows 11. I can open teamviewer but when I try to connect to a machine it doesn't get past the initializing connection screen.

    Hi, I have just looked a bit further into this, can it seems to be an issue if your using the UDP setting within teamviewer. I have turned this off and seems to be ok for now.

    @daveabraham Thanks for this comment. I had been searching for a reason my teamviewer wasn't connecting to most of my clients since upgrading to Win11 release preview. I've been resorting to our backup remote connection while I figured it out. I had the same behavior as described above. Sometimes I could connect and see my desktop, but couldn't click on things. Other times I wouldn't fully connect. (I was thinking it was a display driver issue but apparently not)

    Turning off UDP fixed my issue. I never tracked down why some connections worked (about 20%) but most wouldn't. I never could isolate what was similar on the working connections.

    I have some similar problems, I can connect to my remote windows 11 Pro updated PC, I can logging with some difficulties and when I get to the desktop, when I clic on windows menu, start menu doesn't show, and taskbar display weird things.

    Tell me if you want something to look into thing matter.

    Hi,

    short update to the connection problems.

    According to our analysis, the problem only occurs on machines with special networking adapters and using UDP.

    The problems are related to some issues 'between some Intel “Killer” and “SmartByte” networking software and Windows 11'. Microsoft has announced a fix by an Windows Update planned for the 12th of October.

    Please read https://docs.microsoft.com/en-us/windows/release-health/status-windows-11-21h2#1699msgdesc for some more information.

    To solve the problem for TeamViewer on Windows 11 for the moment, please disable UDP in the options (Advanced > Advanced network settings > Use UDP (recommended)) until you are using the new Windows update (and please remember to enable UDP after that again).

    If you encounter any further problems, please post them here.

    Sorry for the inconveniences.

    Best

    Hello

    I noticed the mouse is out of position when clicking on task bar and some 3D aplications just give a blank screen

    When trying to disable UDP. I go to the options menu but TV crashes as soon as I clock the options link. It does this also when I establish a new connection to a client.


    I have my log file if you need it.

    Using the latest 64 bit version of TeamViewer on all computers...

    Connecting Windows 10 computers to a Windows 11 computer

    Connection is fine if both computers are on the same internal network...

    Connection is made from an external network, but there is no interaction with the Windows 11 computer...

    I downloaded todays Win11 updates and rebooted. I then turned UDP back on within TeamViewer and I was able to connect to a computer I had a known issue with...so problem seems resolved at this point. I'll update if I encounter any connection problems with UDP on.

    Hi there. I just loaded the latest version of TeamViewer on my new PC with a new Windows 11 install, in order to join a meeting and view someone else's screen share (on Windows 10). I wasn't able to see anything but an empty grey screen. I requested they make me presenter to try to share my screen, and when they did, I received no notification to assume the presenter role. When I created a meeting myself and invited them and shared my screen, they also could not see anything but a blank grey screen. I just checked the latest Windows updates and will test more soon, but I wanted to share my experience. Thanks!

    I tried to connect to a Win7 computer (ya I know, luckily it was with the intension of moving some old software off of it) after my previous post and had a similar issue so I turned UDP back off for now and that fixed the issue. So maybe it's only partially fixed by Microsoft.

    Hi @brollins,

    thanks a lot for sharing your experience!

    If you want to, I can arrange a ticket so that you can send us your log files for the Win7 computer to check if it's still the same issue...

    It's one of my unmanaged customers so was probably just a one time event connecting to that machine. I turned it UDP back on so I could watch for other occurrences. I use a Dell WD19 Docking station and a Dell Precision 3560 Laptop. I've noticed the issue when using the docking station which uses a Realtek Network card. I'm not aware of any Intel “Killer” and “SmartByte” networking software on this laptop, so I don't think the problem is exclusive to that.

    Not sure if it is related, but on a laptop with a new Windows 11 install (no upgrade), after a connection to a Windows 10 machine and subsequent disconnection, the laptop will never turn off its screen nor will it sleep. I am pretty sure it is related to TeamViewer because if I stop the TeamViewer service the laptop will turn off its screen and sleep in accordance with its settings. I have installed the Microsoft Oct 12 update, but after that and after unchecking UDP, the behavior is the same.

    Hi @jshulters, thank you for reporting this!

    We looked into the issue but were unable to reproduce this behavior - does the issue still persist for you?

    Best,

    Hi

    I have been using Windows 11 and Teamviewer with no issues at all since august, until now ...

    I installed the latest 'Windows 11 Insider Preview 22478.1000' today, and I am now unable to remote control anything ...

    I can try to connect to a computer, but the remote screen never shows up. I have tried to control several different machines with different OS and I have tried to disable UDP, but I'm not able to use teamviewer from this machine anymore 😓

    I've got the same issue with 'Windows 11 Insider Preview 22478.1000'. I've tried remote controlling a system beside me and on that machine I can see everything happening, but the view of the remote machine is not appearing on my system. I've tried disabling UDP but this has no impact, the screen stays the same.
