For the best possible experience, we recommend doing a fresh installation of your programs and apps on your new Windows 11 PC. Microsoft Store has a variety of third-party apps that can be easily downloaded and installed. On your Windows 11 PC, you can open Microsoft Store by selecting the icon on the taskbar or by searching for "Microsoft Store" in the search box on the taskbar.
For any software not currently available in Microsoft Store, we recommend going to that company's official website and downloading the Windows 11 version from there. In limited circumstances, some older software may not have an updated version that's compatible with Windows 11.
