Remove TortoiseHg from startup on a list of computers

Disable-TortoiseHgStartup.ps1

<#
.SYNOPSIS
    Disables the TortoiseHg startup entry on a list of computers.

.DESCRIPTION
    The Disable-TortoiseHgStartup function uses Invoke-Command to remotely access the registry of each computer in the $ComputerName parameter. It attempts to get the 'TortoiseHgOverlayIconServer' startup entry. If the computer isn't responding or doesn't have TortoiseHg installed, it outputs a message.

.PARAMETER ComputerName
    An array of computer names or a single computer name. This can be either a string or an object with a 'Name' property.

.EXAMPLE
    Disable-TortoiseHgStartup -ComputerName "Computer1", "Computer2", "Computer3"

    This example disables the TortoiseHg startup entry on the computers named Computer1, Computer2, and Computer3.

.EXAMPLE
    $computers = @(
        [PSCustomObject]@{Name = "Computer1"},
        [PSCustomObject]@{Name = "Computer2"},
        [PSCustomObject]@{Name = "Computer3"}
    )
    Disable-TortoiseHgStartup -ComputerName $computers

    This example disables the TortoiseHg startup entry on the computers named Computer1, Computer2, and Computer3, using an array of objects with a 'Name' property.
.EXAMPLE
    Get-ADComputer -Filter * | Disable-TortoiseHgStartup

    This example disables the TortoiseHg startup entry on all computers in Active Directory.
.NOTES
    The function requires that the user running it has the necessary permissions to access the remote registry of the computers in the $ComputerName parameter.
