Will applications built on windows 11 work on windows 10

Question

Hello There,

We are planning to migrate to Windows 11 os in our laptops, Currently have Windows 10 where we develop our apps/dll's and test on other hardware with Windows 10 os. If we migrate, Then I would be building apps/dll's in Windows 11. But my apps/dll's still need to run on Windows 10. Do you see any compatibility problems already due to this migration? What kind of problems could occur and how to resolve them?

Thanks for the feedback.

Answer

Microsoft has made changes to the hardware requirements for Windows 11, but app compatibility is set to remain the same.

Answer

You can target Windows 10 SDK : https://learn.microsoft.com/en-us/cpp/windows/how-to-use-the-windows-10-sdk-in-a-windows-desktop-application?view=msvc-170

Answer

Before migrating to Windows 11, you need to test all your needed applications in only one machine. Not all the laptops are upgraded to Windows 11, since few laptops might be added with unsupported intel or amd processors.
