If it's up to date you probably can't change the password directly via recovery however you can with a windows installer or linux USB.

If you have a windows installer DVD/USB just boot to that and select your language, in the corner there should be a 'repair your PC' button or something like that, click it and click advanced > command prompt

find the drive letter with your windows install on it (this can be done with diskpart or similar, it's probably not C:\ as the USB is probably using C:\.

once you find the letter rename osk.exe to osk.exe.old with this command (replace X with drive letter)
ren X:\Windows\System32\osk.exe osk.exe.old and copy cmd.exe/rename copy to osk.exe (effectively replacing the On screen keyboard with CMD) (hit f to select file if it asks)
xcopy X:\Windows\System32\cmd.exe X:\Windows\System32\osk.exe now you can reboot to Windows and select the little ease of access thing in the corner of the login screen

 
Click On-Screen Keyboard, it should open a CMD window.

now you can change the account password by typing: (replace username with the username (if you don't know it there should be a folder in C:\Users\ titled the username) and password with the password you want to set)
net user USERNAME PASSWORD At this point you should be able to log in with the new password

Be sure the delete the OSK.exe (which is actually CMD) and replace it with the original after you log in.
 
There might be a way to change user passwords via Windows Recovery USBs however every time I've tried it either hasn't worked or requires the existing admin account's login (making it useless)...

You can't. Software installer puts stuff in multiple places, and if all of those aren't found, it wont work. You usually can export settings, or backup them as config files for easier launch. But you still need to reinstall whole software.
 
Some software have option for portable install, where everything is kept inside single folder. This might mean there's little less configuration or saved profiles. Also using launchers like Steam and Origin, you can move whole game folders and discover them on new install. The launcher will still need to be installed.
