An upcoming version of Microsoft Phone Link lets you select and copy text from within images synced from your Android phone. The feature is live now in Release Preview Insider builds, so it should roll out to everyone soon.
Phone Link (called Link to Windows on the phone side) lets you sync calls, messages, notifications, and images — and cast your entire phone — from your Android phone to your Windows computer. It also works in a more limited fashion with iOS devices, which only sync notifications, messages, and calls over Bluetooth.
