Systems Deployment

Lets say my district uses an admin account called techadmin as the main administrator account to login into any computer. This account previously existed on my syspreped computer. Using my unattend.xml I want to create this account, change its password, and then login into it afterwards.

However after the machine images and reboots, I get an error saying the password is incorrect, and sure enough the password doesn't work. What am i doing wrong?

Here is my unattend.xml
