Many applications, files, and settings will migrate as part of the upgrade. However, some applications or settings may not migrate.
For anti-malware applications, Windows will check to see if your anti-malware subscription is current (not expired) and compatible during the upgrade.
If the anti-malware application is compatible and current, your application will be preserved during the upgrade to Windows 10.
If the anti-malware application is incompatible, Windows will uninstall your application while preserving your settings. After upgrade is complete, if your anti-malware provider has informed Microsoft that it has made a compatible version available for your active subscription, Windows will notify you to install the latest version available with the settings that were set prior to upgrade.
If your anti-malware subscription is not current (expired), Windows will uninstall your application and enable Windows Defender.
Some applications that came from your OEM may be removed prior to upgrade.
For certain third party applications, the "Get Windows 10" app will scan for application compatibility. If there is a known issue that will prevent the upgrade, you will be notified of the list of applications with known issues. You can choose to accept and the applications will be removed from the system prior to upgrade. Please be sure to copy the list before you accept the removal of the application.
We’ll keep you on like-to-like editions of Windows. For instance, if you are using Windows 7 Home Premium, you’ll upgrade to Windows 10 Home.
