Change username/password configured on logon tab of Windows Service - Powershell

This my another part of List account configured on logon of Windows Service and in this there is a recipe to (Setup service account) change or replace account username/ password on windows service logon tab. Before running make sure your account has permissions or admin rights to change into windows service. Also make sure you open powershell as administrator. 

You can check my earlier post List account configured on logon of Windows Service, how to use this script, if you still have any issue drop a comment on this post I will try to resolve it.

 function Set-ServiceLogonAccount {  
 <#  
  .Synopsis  
   Change or set username password on Service logon Account  
  .Description  
   Make sure you open powershell with as administrator and you have appropriate permissions to modify service settings. You must specify Service name instead of display name.  
  .Example  
   Set-ServiceLogonAccount -ComputerName 192.168.33.51 -LogonUserName vcloud\vkunal -LogonPassword Computer@1 -Service lanmanserver -Credential (Get-Credential)  
     
   It make changes on service lanmanserver on remote computer 192.168.33.51, logon username is changed to vcloud\vkunal and password is set to Computer@1, credential is your remote login credentials.  
  .Example  
   Set-ServiceLogonAccount -LogonUserName .\test -LogonPassword Computer@1  
   By default if only logonusername and logonpassword paramter given it make changes to localhost and service is lanmanserver.

In the first screenshot I am setting local account on local machine,

In this screenshot I am modifying logon account on remote server, service is lanmanserver, also I have mention credential which will popup for username password to connect to remote server.

Here is parameters information
-ComputerName: If not specified default is localhost (this syntex can take value from pipe as well)
-LogonUserName:  Service account username
-LogonPassword:  Service Account password
-Service: if not specified default is lanmanserver, you have mention service name not display name
This is final result from both local and remote computer from services.msc
-Credential: Incase if remote computer in another domain or if you are not administrator you can use "-credential (get-credential)" to connect. otherwise for same domain this parameter doesn't required.
-Protocol: By default it uses legacy wmi dcom protocol to connect, there is another option wsman which use PSRemoting protocol.
