Hi co,
I'm Sumit, here to answer your query at the Microsoft Community.
The Reset removes all the apps, so apps not being there is expected. For the files, are you sure you are not being logged in to a temporary account?
Please check if you can find your files in C:/Users/<username>/ or C:\Windows.old\Users/<username>
Let me know how that goes.
Hope that helps, and rely on us for any further inquiries. All the best.
