When using the Windows Upgrade Assistant to upgrade to Windows 8, the following will occur:

1. Windows Upgrade Assistant will verify whether your computer can run Windows 8 and provide a detailed compatibility report. This report contains information about issues that may need to be addressed before and after the upgrade, as well as app and device compatibility.

2. Windows Upgrade Assistant includes a built-in download manager that allows you to start, stop, and resume the download process at any time. It also checks to ensure the download completed successfully.

3. After the download is complete, you can choose how and when to install Windows 8. You can continue the installation on your current computer or create installation media to install on another Windows-based computer.
