Hey there jrmccomas! 

Thanks for bringing your question here to the Apple Support Communities. It sounds like you're either using iTunes on that PC or iCloud to keep your items in sync. Having the ability to access your calendar and photos on either device at any time is crucial. Here are a few tips to help make this happen. 

Get the latest version of iTunes

Download iCloud for Windows

Select the option that you recall using prior to the Windows 10 update. 

Have a phenomenal day!
