Welcome to the forum for the 1Password for Windows 10 app!
The new app is now in the "beta" phase of development—thanks a million for your help, so far!—and we'd love to keep getting your feedback.
In the Store app on your Windows 10 device, just (a) search for the 1Password Beta app, and (b) click the Install button.
The first time you launch the app on one of your Windows 10 devices, enter your e-mail address so we can keep you up to date on developments and new releases.
