Phil Harvey:
StarGeek has documented the behaviour of the Windows Title Property:

When you set the Title from Windows Properties, the following tags are set:

1. EXIF:ImageDescription
2. EXIF:XPTitle
3. IPTC:Caption-Abstract
4. XMP:Description
5. XMP:Title

And when populating the Title Property, Windows will take the value from the first existing tag with the above order of priority.

And deb27 has documented the behaviour of the Windows Subject Property (for Windows 7):

When you set the Subject from Windows Properties, the following tags are set:

EXIF:XPSubject

And Windows will populate the Subject Property from the following fields, in order of priority:

1. EXIF:XPSubject
2. EXIF:ImageDescription

Notes:
Date Taken - When setting through Windows, only the date appears to be editable.
Title - The priority that windows fills this tag is different for jpegs and tifs.
IPTC Data written - Preliminary testing seems to indicate that these tags are not created by default.  I still need to test whether the tag or just the IPTC block needs to exist.
RatingPercent - Setting: 5 Stars = 99, 4 stars = 75, 3 stars = 50, 2 stars = 25, 1 star = 1, 0 stars = removes tags.  Reading: 88-100+ = 5 Stars, 63-87 = 4 stars, 38-62 = 3 stars, 13-37 = 2 stars, 1-12 = 1 star, no tag or 0 = 0 star
PNG - Png files only seem to have one tag related property for Windows

Credits:
deb27 - Subject property for Windows 7.
lewisn - updated comment info

Edit:  I figure that consolidating all this info into one post is better than spreading it out through a thread, unless there's any objection to that.  So I'll add any info from any other posts into this post.

StarGeek:
Big revisions and corrections.

Somehow I seriously messed up the details for Date Taken.  I double checked it and the above posted info seems correct, at least for Windows 8.1.

José Oliver-Didier:
This post is a very useful reference.

I also stumbled upon this MSDN page, which is more developer oriented. I believe it can also help out folks trying to understand how photo metadata is read and written in windows:

Microsoft Photo Metadata Policies:

StarGeek:
Thank you for that link.  I never found anything like that when I went looking for info.
