How to change path to executable for a Windows Service?

I want to change the path to the executable for a service from the command line.

How can I do that?

I want to run another .EXE from that service's path to executable.

You can use the sc config command to change the path a service points to:

SC CONFIG YourServiceName binPath= "C:\SomeDirectory\YourFile.EXE"

This will update the service called YourServiceName and change the "Path to Executable" entry to C:\SomeDirectory\YourFile.EXE. You will want to restart your service afterwards, which you can do with:

NET STOP YourServiceName & NET START YourServiceName

You will need to do that in the registry:

HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services

Navigate to the service, then modify the image name to reflect the new path

As always, make a backup of the system PRIOR.

The answer provided above works great, I can't reply to it, but to add up, in case you need to have quotes or other arguments in the path, say to fix an unquoted path vulnerability in the registry, like an imagepath, you can do the following from CMD as admin:

(e.g. for C:\Program Files (x86)\YourService\YourProcess.exe)

SC CONFIG YourService binPath= "\"C:\Program Files (x86)\YourService\YourProcess.exe\"

you can do the following from powershell as admin:

 SC.exe CONFIG YourService binPath= --% "\"C:\Program Files (x86)\YourService\YourProcess.exe\"

These will give you the following result:

"C:\Program Files (x86)\YourService\YourProcess.exe"

...bloody arguments and escaping parameters are a nightmare! Hope this helps someone in the future.

You could also do it with PowerShell:

Get-WmiObject win32_service -filter "Name='My Service'" `
    | Invoke-WmiMethod -Name Change `
    -ArgumentList @($null,$null,$null,$null,$null, `
    "C:\Program Files (x86)\My Service\NewName.EXE")

Or:

Set-ItemProperty -Path "HKLM:\System\CurrentControlSet\Services\My Service" `
    -Name ImagePath -Value "C:\Program Files (x86)\My Service\NewName.EXE"
