Summary

This PR updates the Windows Service installer documentation to include the Account attribute in the WiX ServiceInstall element, which is a security best practice that was previously missing from the example.

Changes

1. Added Account attribute to ServiceInstall

Updated both the article and sample code to include Account="LocalService" in the ServiceInstall element:

<ServiceInstall Id="ServiceInstaller"
                Type="ownProcess"
                Name="App.WindowsService"
                DisplayName="$(Name)"
                Description="A joke service that periodically logs nerdy humor."
                Start="auto"
                Account="LocalService"
                ErrorControl="normal" />

2. Fixed directory structure

Updated the directory structure to use StandardDirectory Id="ProgramFiles6432Folder" as requested in the original issue to eliminate compilation errors. This replaces the older StandardDirectory Id="ProgramFiles64Folder" approach with the correct WiX v4 syntax.

3. Added documentation

Added explanatory text about the Account attribute and its common values:

  • LocalService: A built-in account with reduced privileges and no network credentials (recommended for most services)
  • NetworkService: Similar to LocalService but has network credentials
  • LocalSystem: The highest privilege level (use with caution)

Why This Matters

The Account attribute is important for security best practices when creating Windows services. Without it, the service may run with higher privileges than necessary. LocalService is a safer default than LocalSystem as it operates with reduced privileges, following the principle of least privilege.

The directory structure change to ProgramFiles6432Folder ensures the installer compiles without errors in WiX v4.

Files Changed

  • docs/core/extensions/windows-service-with-installer.md - Updated article with Account attribute, corrected directory structure, and explanatory documentation
  • docs/core/extensions/snippets/workers/windows-service-setup/App.WindowsService.Setup/Package.wxs - Updated sample code to match
Original prompt

This section details on the original issue you should resolve

<issue_title>Service Install example is out of date.. should implement instead</issue_title>
<issue_description>All of this part

<Directory Id="TARGETDIR" Name="SourceDir">
            <Directory Id="ProgramFilesFolder">

                <!-- Create a folder inside program files -->
                <Directory Id="ROOTDIRECTORY" Name="$(var.Manufacturer)">

                    <!-- Create a folder within the parent folder given the name -->
                    <Directory Id="INSTALLFOLDER" Name="$(Name)" />
                </Directory>
            </Directory>
        </Directory>

Can be replaced with

		<StandardDirectory Id="ProgramFiles6432Folder">
					<!-- Create a folder within the parent folder given the name -->
					<Directory Id="INSTALLFOLDER" Name="$(Name)" />
		</StandardDirectory>

and visual studio wont display the compiling error
