The Windows 10 installer will assess whether or not a particular computer's configuration is suited to Windows 10 (though it may not always get that right) and prevent users from installing the new operating system unless it believes their hardware is compatible.
In addition, users will be notified before they decide to update if some software that they use will be removed as part of the upgrade process. Importantly, Microsoft has done away with Windows Media Center in the latest version of Windows, so people who really want to keep that around will need to avoid upgrading, or find other applications to take its place.
Business and education users will also have at least a few extra days to wait before they get their hands on the new OS. While the Home and Pro versions will be available on Wednesday, the Enterprise and Education versions of Windows 10 won't be open for download by Microsoft's volume licensing customers until August 1. Certain features like Enterprise Data Protection and Business Store for Windows 10 won't be available until later this year, either.
