Where Windows 11 fits
Use it when preparing an installation or reinstalling a supported Windows computer.
Check before you choose
Check hardware eligibility, licensing and backups before changing the operating system.
Find the right edition
Start with the destination for your device or the publisher's website. Use the current requirements and terms there to confirm the edition you need.
Compare the workflow
A missing dependency does not necessarily require a new operating system. Read the application's documented requirement, match the architecture and obtain the component from the publisher rather than a third-party DLL website.
