You’re not dreaming: You can finally use iMessage on your Windows PC—if Microsoft picks you, that is. The feature is currently in early stages of testing for a select group of Windows Insiders. If you enroll your PC in the Insider Program, you might have a shot at trying this feature early.
Once it does hit your PC, you’ll be able to wirelessly connect your iPhone to your Windows computer through Phone Link for iOS, sending and receiving not only iMessages, but also text messages and phone calls, just as you can with an Android phone. However, it’s not a perfect solution: As of the announcement, there’s no support for group chats, media (e.g., photos, videos, or GIFs), or accessing message history prior to setting up Phone Link for iOS.
Android isn’t left out of the Phone Link updates, either. Samsung users can now turn on their personal hotspot from Windows’ wifi settings, as well as carry over their browsing history from mobile to desktop.
