Problem With Moving User Folder During Clean Install Win 10  

Asus M5A7-R2.0
AMD 4300 Processor
16 gig RAM
1 SSD Win 10 OS C:
1 HD Basic Data D:
1 HD Dynamic Data I

Built this PC for my wife several years ago. Originally had the Win 7 OS on the SSD and the user folder on the HD D: created with a fresh install of Win 7 using sysprep and an answer file.

Recently I made the mistake of creating a Win 7 Software RAID 1 mirror which failed.

To fix the problem, I just did a clean install of Windows 10 again using sysprep and an answer file. Specifically, prior to running sysprep while still in audit mode, I installed most of the programs that both of us use so I could create a "golden" image. After software was installed, I ran sysprep with the generalize, OOBE, and shutdown switches.

Everything worked out for the most part. However, as can be seen from the image below, I wound up with my wife's old user folder, "Sarah." However, there are also 2 other folders, default and 12404. The default folder is the bigger one having over 7 gig of data. The 12404 folder has about 5. I am suspecting that the 12404 is now the active folder. However, I have no idea how these numbers were assigned rather than my wife's first name. What I want to know is whether or not I can somehow change the folder name and move all of the information from the old profile into it. I want to know if I can rename the active folder Sarah and put all the old information.....the folders like documents, etc. from the old Sarah folder to the new one.....and how to do it.
