Let me check the flights, a beer is worth some efforts
Yes, it's possible. Do like this:
Start SysPrep as told in that tutorial step 9. Boot to
Audit Mode by selecting
Enter System Audit Mode and
Reboot and then clicking
OK as shown in this image:
PC reboots now, entering a so called
Audit Mode. Delete everything you want to, for instance that account called
User.
Again, start SysPrep. This time select
Enter System out-of-Box Experience (OOBE) and
Shut Down, check the box
Generalize as shown in this image:
This syspreps your PC, generalizing it:

Note
What does Sysprep generalizing do to my Windows 7 setup?- All system specific information is removed or uninstalled
- Security ID (SID) of your hardware setup is reseted
- All system restore points are deleted
- All event logs are deleted
- All personalization is removed (taskbar, toolbars, folder options, start orb etc.)
- Built-in administrator account is disabled (if it was enabled) and needs to be later re-enabled if again needed
What happens when booting first time after sysprep generalizing?- First boot configuration (OOBE) is run
- New SID is created
- Re-arm counter is reseted if not already re-armed three times
- Windows 7 is booted using first boot default drivers and settings
That's it.
