Lost all bookmarks in my user profile after latest microsoft windows update on 5/15/15

Question

Last night at 2am when I went to hibernate my computer as I usually do, I saw that there were some automatic windows updates to be installed. Since I have Windows XP and Microsoft has supposedly ceased support, I cancelled the hibernation and got on the internet to make sure that Microsoft was pushing out these updates and what they were for. Everything seemed kosher so I closed the internet and all of my programs, and proceeded to shut down the computer allowing the updates to install.
Much to my chagrin this morning, I discovered that my user profile had essentially been wiped out. The user profile name was still there and the password still worked, but when I got in the whole profile had been restored to its initial settings. Most of my files that I had on the desktop are gone and when I launched FireFox, it had been reverted to its originally downloaded version (years ago) and all of my many, many bookmarks were gone. I did find some files in My Documents, but the bulk of the documents were not under my documents and appear to be gone.
I did find some files in a TEMP folder and saved all of those. Fortunately I did back up my computer about a month ago, but stupidly did not back up my bookmarks. I do have a back up from a couple of years ago that I can retrieve, but everything since then appears to be gone. There are many files in the TEMP file that I cannot identify and am hoping and praying that my bookmarks are still in the midst of them. I did a search for Mozilla FireFox profiles through my dos prompt, but it only found a default profile that is likely associated with my admin user account that I generally do not work on for security purposes.
I have searched all day on the internet for solutions with no luck. I would be most appreciative if anyone can provide some guidance that may be of help.

Make sure to copy the profiles.ini as well if you copied the xxxxxxxx.default folder from that old Windows account.
