I encounter the following super annoying issue:
TeamViewer 15.75.5 for macOS on the remote machine.
TeamViewer 15.76.3 for Windows on the remote machine.
Windows 11 Pro 25H2, macOS Tahoe 26.3.1.
When the machine is on the Windows logon screen after a fresh reboot, TeamViewer's Action menu does have the Send Ctrl-Alt-Del option. However, when I successfully logon, the option immediately disappears from the Action menu.
When subsequently locking the machine, the options does not resurface. In essence, the second time the Windows logon screen is displayed - after one successful login - the option is gone forever.
It only comes back, when I reboot the machine.
This is extremely annoying, since some activities - e.g. changing my password - do require Ctrl-Alt-Del to be send.
Interestingly enough, sending Ctrl-Alt-Del is available on the iOS version of TeamViewer.
The remote machine is part of a Windows domain.
Do you guys have any ideas?
