To avoid UAC issues during connections to a Service Case (session code), please connect to the service case using Windows Authentication instead of the password.
This requires the Windows account credentials of an admin account on the device that created the service case.
If you are connecting to a customer running a QuickSupport module, there are a few additional steps needed in order to interact with remote UAC prompts.
Please see below for the steps required in order to interact with the UAC prompt on a remote machine when connected to a TeamViewer QuickSupport:
Hint: If you are using QuickSupport with Session codes (Service Cases), after your partner starts TeamViewer QuickSupport on their device, select Remote Control using Windows authentication to the right of the service case in your Computers & Contacts window. See chapter above.

Select Switch to Windows authentification and enter the remote computer's local admin credentials and Click Log On.
Hint: When you click Log On please be advised you will not be automatically connected. You will see a new message appear at the bottom of the TeamViewer application window:
The remote computer will be prompted with a UAC prompt from TeamViewer. Instruct the remote user to select YES to allow TeamViewer to make the requested changes.
Once the user accepts the UAC prompt, their TeamViewer QuickSupport will restart. Reconnect to the ID, and you will be prompted with the Windows credentials login screen again. Re-enter the local admin credentials, and you will be connected to the device.
You are now connected to your partner’s computer and can control the UAC as you wish.
