Due to a random generator, we never know the Administrator username on a server. However, our policy prior to taking a snapshot is to change the name and password to ADMIN and Password1, which is where my problem is...I wrote a powershell script that shows me the name of that account, but I do not know how to write over that name and make it ADMIN.
This is the part of the script that finds the account name:
Get-ADComputer $strComputer | ForEach {
$Accounts = Get-WmiObject -Computer $_.Name -Namespace root\CIMV2 -Query "SELECT * FROM
Win32_UserAccount WHERE LocalAccount = TRUE"
ForEach ($Account In $Accounts)
{
If ($Account.SID -match "S-1-5-.*-500")
{
$Admin = $Account.Name
Break
}
}
Write-Host $Admin
}
Any help would be appreciated.

Well, no one helped, but that is ok...after much trial-n-error, I figured it out, but it is causing an undesirable output that I need help with. In the below code, all the lines down to "$strComputer = "$x"" are used to produce a windows input form so you can type in a computer name. However, though the last three lines of code changes the Administrator user account to ADMIN, it also displays this on the screen:
__GENUS : 2
__CLASS : __PARAMETERS
__SUPERCLASS :
__DYNASTY : __PARAMETERS
__RELPATH :
__PROPERTY_COUNT : 1
__DERIVATION : {}
__SERVER :
__NAMESPACE :
__PATH :
ReturnValue : 0
Does anyone know how to stop this output from being displayed? Thanks in advance, here is my code:

When you run the rename method pipe it to Out-Null,or even better is to assign it to a variable
$change=$AdminAccount.rename("ADMIN")
Now you can check the return value and anything other than 0 indicates a problem.
if ($change.returnValue -ne 0) {
Write-Warning "Failed to rename account. Return value is $($change.returnValue)"
