At symbol (@) on Swiss German keyboard

Dear Martin,
Thank you for your feedback.
For us to better understand the issue, please, perform the following steps:
1. Launch your Virtual Machine > Click on the Windows start icon > type Language settings and press enter > Next to your Language, select the 3 dots on the right.


2. Select "Language Options" > Down below you will see all the keyboards that are currently installed.
3. Please check if you have a keyboard layout that ends with "-Parallels".
e.g on my mac I have the keyboard "French-Numerical" installed. To use the same layout in my Windows 11 virtual machine I need to set the keyboard layout as "French (Numerical, Apple) - Parallels".
4. If the keyboard installed inside your Windows virtual machine doesn't have the "- Parallels" extension > Click on Add a keyboard > Select the One that is currently installed on your mac along with the Parallels extension.
5. Press the Option+Shift button to switch to the Parallels Keyboard layout inside the virtual machine > check if this resolves your issue.

If the issue persists, for further investigation, kindly provide us with the following information:
a. Start the Mac On-Screen keyboard (open Spotlight > type On-Screen keyboard) and take a screenshot with pressed Shift.
b. Start the On-Screen keyboard inside your virtual machine and take a screenshot with pressed Shift.
c. From your mac > Click on Apple Icon on Top left corner > Click on "System Preferences" > Choose "Input Sources" (Take a screenshot)
d. From your Windows Virtual Machine > Click on start button > Type "Language settings" > Click on the 3 dots next to the preferred language > Language options (Take screenshot)

Thank you!
