  If you want to have a consistent delay pattern for your ToolTip windows, you can set the <xref:System.Windows.Forms.ToolTip.AutomaticDelay%2A> property. The <xref:System.Windows.Forms.ToolTip.AutomaticDelay%2A> property sets the <xref:System.Windows.Forms.ToolTip.AutoPopDelay%2A>, <xref:System.Windows.Forms.ToolTip.ReshowDelay%2A>, and <xref:System.Windows.Forms.ToolTip.InitialDelay%2A> properties to initial values based on a single value. Every time the <xref:System.Windows.Forms.ToolTip.AutomaticDelay%2A> property is set, the <xref:System.Windows.Forms.ToolTip.AutoPopDelay%2A> property is set to 10 times the <xref:System.Windows.Forms.ToolTip.AutomaticDelay%2A> property value. Once the <xref:System.Windows.Forms.ToolTip.AutomaticDelay%2A> property is set, you can independently set the <xref:System.Windows.Forms.ToolTip.AutoPopDelay%2A> property, overriding the default value.
 
- The maximum time you can delay a popup is 5000 milliseconds. For longer durations, use the <xref:System.Windows.Forms.ToolTip.Show%2A> method to control the exact moment when the ToolTip is displayed.
+ The behavior of this property varies by Windows version:
+
+- On Windows 10, the maximum time you can delay a popup is 5000 milliseconds. Values greater than 5000 ms are clamped to 5000 ms.
+- On Windows 11, the default value causes tooltips to remain visible indefinitely. When set to a custom value, there's no 5000 ms limit, and the tooltip displays for the specified duration.
+
+For longer durations or precise control over when the ToolTip is displayed, use the <xref:System.Windows.Forms.ToolTip.Show%2A> method.
