Password reset with Live Account - What files are "encrypted files" in Windows 10

I have access to my account through live login and my Windows 10 pin but I need to log in from safe mode to reinstall my video drivers in a clean manner. To access this account in safe mode I would need to use a proper local password. Between using pins to log into my devices and Microsoft's constant nagging to come up with new convoluted passphrases (I know it all happens in good intent) for the first time in ever I forgot my desktop password. Before I run off with some third party tools to edit my registry or whatnot I would like to ask which files would I loose if I just use the ordinary password reset from the Computer Management Panel.

As shown here

I read up on EFS a little bit but I couldn't figure out which files are it affect by default running Windows 10 and if it is possible to use builtin programs like Cipher.exe to mitigate dataloss. Lastly would it be advisable to use this built in functionality in this case at all ?
