Running W10 64bit desktop which was upgraded from W8.1.

I have read that there is both Windows Photo Gallery and Windows Live Photo Gallery.  I do not know which of them is correct for my W10 OS (which is current with Windows Updates).   If I have Essentials or either of the 2 photo galleries I mentioned, I don't know it.  I do have MS Office 2007 which I installed from a DVD.

I don't see any of the previously mentioned applications (except Office 2007) listed in Control Panel | Programs...

What to do?  What to look for? What to install?
