Important: If you’re running Windows 8.1 Enterprise, Windows 8 Enterprise, or Windows 7 Enterprise and your system language isn’t English, Chinese Simplified, or Brazilian Portuguese, you can only keep your personal files when you upgrade. You won’t be able to keep your apps or Windows settings.

Test your applications

Most existing business apps should work with Windows 10 Technical Preview for Enterprise, but you might run into issues with custom or older apps. To get the jump on potential problems, start running your apps on your Technical Preview test computers—and keep running them to see how the updates affect compatibility.

We also recommend that you:

Catalog your current applications so you have a complete list, including version numbers or names.
Reduce the number of versions you support for a single app.
Prioritize the apps you want to test.
Test each app by performing typical day-to-day tasks.

If you find that an app isn’t compatible with Technical Preview, try upgrading the app to a newer version, fixing the app, or retiring the app and finding a new one.
