You're probably not choosing the full recovery option. Most hidden partitions give you two options. A. a recovery of the OS and keep programs, personal files and user names intact. B. You fully format the drive and install the OEM copy of Windows with their crapware.
There is no way the previous owner could have created an OEM recovery partition with his name still intact. A backup image of course, but that's not what we are instructing this poster to do (use a backup image, I mean). Good luck!
