What is UserPreferenceChangedEventHandler in winform applications for C #?

Question

I found that some of my winform controls, such as DataGridView and ToolStrips, are called UserPreferenceChangedEventHandlers. I have no idea what control settings these links will generate and why such links keep my control in memory. How to remove such links from this event? Thanks.

This is the delegate type for the SystemEvents.UserPreferenceChanged event. This event fires when Windows sends the WM_SETTINGCHANGE message. This usually happens when the user uses the control panel applet and changes the system settings.
