With this PowerShell script you will be able to change the user name and password of any Windows service. It can work against 1 or more services at the same time. The process will stop the service before changing the credentials and it will start it after completion. If the service is not running before the change, the service will not be started after.


  1. The ps1 file should be executed elevated. If not the change method will fail.
  2. The account running the script must have:
    • Rights to execute Powershell Sonrisa
    • WMI Access (since we are accessing the win32_service class)


  • You can change the user name and password of 1 windows service or many.
  • it can interact with a remote server.


    All parameters are mandatory. If you don’t provide them, powershell will ask for them.

    • UserName: This would be the new user name. Examples:
      • .\Administrator
      • DomainName\Administrator
    • Passwordthis is the user password. If the password contains a $ you must pass the parameter enclosed in ‘’ (the symbol $ is not allowed in ps)
    • Service: This is the service name where you want to change credentials. WildCards characters are supported since the query is filtering using a like expression. Examples:
      • ‘MSSQL’–> it will act over all SQL Server processes in the server
      • ‘BTSSVC%’  –> it will act over all BizTalk processes in the server
    • ServerNName of the server where you want to change the service.
    • SecondsToWait: This is the time in seconds that the script will wait before starting the service again. Default is 1. 


The following screenshot shows you the output of the script:


  • Changing the user and password of all BizTalk host instances:

    .\changeUser.ps1 –UserName .\Administrator –Password admPwd –Service ‘BTSSVC%’ –ServerN ServerA –SecondsToWait 2


  • Changing the user and password of the SQL Server Agent:

    .\changeUser.ps1 –UserName .\Administrator –Password admPwd –Service ‘SQLSERVERAGENT‘ –ServerNServerA –SecondsToWait 2
