    I'm grateful I keep my SSD purely for OS purposes but because of my obsession with clearing out any foreign or suspicious folders and files I got rid of something vital which I'm now finding out is necessary for the OS. If I don't have a backup am I gonna have to take a dive and reinstall Windows 10 or is there some way to get back that file? (It's deleted, not in the recycle bin)

    You can use Rstudio to see if you can recover it (possibly connecting your ssd to another pc)

    You can boot with the recovery consolle or nt password recovery and enable the Administrator user, once you're logged as administrator you can recreate a new user and move there most of your user settings (not the ones stored in the registry, obviously) and allo of your personal files.

    I can't imagine a situation where you are able to casualy delete such important files like ntuser.dat! They are seriously locked for a reason. You know when you have to jump through some very serious hoops to delete such a important file it might be best to investigate beforehand what this file is for. Not even a backup or googling the file name before you do such a serious operation is never good practice.

    I think you also deleted other more or less important files when you deleted the ntuser.dat. It is best you make a clean install of windows. You will get always problems down the line with important files missing.

    I hope you have learned an important lesson here to

    a) never do such serious tasks without a recent backup

    and

    b) inform yourselve WHAT you are doing or leave it as is!

    I also advice you seek out a medical profesional with help for your obsession. At least it harmed your Windows installation. It's better to seek out help before it spreads to other areas of you life.

    If the files were deleted as usually, using windows default delete function, then they all are on hard disk and also all can be recovered. Simply is needed to boot from any bootable disk and run recover program. For example I have used one old, but good Spotmau Power Suite 2012.
    And of course, always is possible use built in "Administrator" account and then You can reset any password. This is the simplest way always.

    ntuser.dat is HKEY_CURRENT_USER, so by deleting it you have lost the contents of the respective user's registry hive.
    For a user profile, restore the default ntuser.dat from install.wim (in \Users\Default).
    For a service profile you can try restoring the default from install.wim (in \Windows\ServiceProfiles).

    It is, however, an excellent learning experience.

    You could have saved your derogatory comment about seeking a medical professional (are you skilled to make a proper diagnosis?), it's totally useless....
    Finally OP had the courage to post about an awkward action....he surely did not do that to harvest sarcasm ;)
