Hello, welcome to the Microsoft community.
Based on your feedback, you want the drawing software on your computer to maintain the aspect ratio when dragging and desktop images.
I have tested the method you mentioned, and it is indeed ineffective to drag by holding down shift.
In the built-in software on the computer, it is indeed impossible to do this.
The drawing in the system only retains the most basic functions of the drawing software.
So I feel very sorry.
If you really want the drawing software to have this feature
If you have any suggestions for this feature, you can do so through:
Send feedback to Microsoft with the Feedback Hub app - Microsoft Support
Submit your ideas and suggestions, the development team will regularly review the submitted ideas or fixes.
