Setting password for Autologon Default user in registry

Question

Hi friends
I don't know is this the right forum to ask this question:
me along with my colleges are doing some exercises to improve our learnings, so we have setup a test lab which has a test DC & 10 test client computers running windows 8.1 
as we know, when computers join to domain, the item related to Autologon is removed from netplwiz.
I know that to be able to use Autlogon feature in joined computers, we can restore the above item by creating the required items via any method like the following:
$regpath="HKLM:\software\Microsoft\Windows NT \CurrentVersion\Winlogon "
New-ItemProperty -path $regpath -Name AutoAdminLogon -PropertyType String -Value "1" -Force
$regpath="HKLM:\software\Microsoft\Windows NT\CurrentVersion\Winlogon"
New-ItemProperty -path $regpath -Name DefaultDomainName -PropertyType String -Value %USERDOMAIN% -Force
$regpath="HKLM:\software\Microsoft\Windows NT \CurrentVersion\Winlogon "
New-ItemProperty -path $regpath -Name DefaultUsername -PropertyType String -Value “administrator” -Force
the above lines provide required info for Autologon, except the password of the user.because of this we have to sit at every test client & open up netplwiz & manually enter the password for default Autologon user.
is it possible to define the password for this user as well in the registry?  so that we add it to above lines & save them as a PS script & run that PS script on our test systems so that we don't have to sit at each test client
& manually set password for default user for Autologon.
I mean I need when we power on our test clients, they automatically login via domain administrator credentials & be ready to use
thanks

The documentation for this might prove helpful:

According to the above:
If you disable automatic logon by setting the value of AutoAdminLogon to 0, delete the value of
DefaultPassword, which is stored and displayed in the registry editor in plain, unencrypted text.
(Hint: I found this very quickly by searching for "autoadminlogon" using a search engine.)
