function Reset-WPFCheckBoxes {
    <#

    .SYNOPSIS
        Set WinUtil checkboxes to match $sync.selected values.
        Should only need to be run if $sync.selected updated outside of UI (i.e. presets or import)

    .PARAMETER doToggles
        Whether or not to set UI toggles. WARNING: they will trigger if altered

    .PARAMETER checkboxfilterpattern
        The Pattern to use when filtering through CheckBoxes, defaults to "**"
        Used to make reset blazingly fast.
