I'm certain there's a plist somewhere that has this information, but haven't found it so far.
There are certain underlying settings that can be changed in Terminal using the 'defaults' command. A very common 'finder'-related usage, for example, is to permanently show all hidden files (like CMD-SHIFT-dot but stays that way) with the Terminal command:
defaults write com.apple.Finder AppleShowAllFiles true
This tells 'defaults' to write to the preferences related to a domain called 'com.apple.Finder'. It looks for a key called 'AppleShowAllFiles' and sets it to 'true'. ('YES' is shown in some examples. It means the same thing.)
Note: if you're going to use this command, make sure to follow it with the command 'killall Finder'. This re-launches Finder to make the change take effect.
I'm sure that someone at Microsoft has figured out which `defaults` item(s) must be added or changed to set that `kind` value. However, I've not been able to find it so far, and it seems not to be publicly documented anywhere.
Side comment: this isn't a hack at all. It's an advanced feature of the OS that is used by many apps and super users. Whoever caused this at Microsoft may not even realize they were affecting all of Finder with the command they used - or they might have done it on purpose, but did it with full intent of making your Microsoft stuff easier to find.
Either way, if I find an answer before this post expires, I'll definitely post it!
