Hey there farmbroker,
Thanks for reaching out to Apple Support Communities. We understand you’d like to know how to get the messages on your iPhone to appear on your Windows 10 PC. There is no app or supported service that does this at this time. You can forward full conversations to your email so you can view them on your PC. Take a look at this article for info on doing this:
How to forward SMS/MMS text messages from your iPhone to your iPad, iPod touch or Mac
As far as Photos, Mail, and Calendar events, you can use iCloud for Windows as seen here:
Set up iCloud on your Windows PC
You’re welcome to leave feedback about changes you’d like to see to iCloud for Windows, like suggesting a text syncing service, here:

Take care.
