My friend, have you ever configured an LED signboard before? If not, what you will learn will shock you...
...a lot of these boards are controlled by proprietary chinese software that only functions on Windows XP.... even today.
As to why they don't have a more modern OS connected to a signboard that obviously supports at least VGA and probably HDMI.... I don't know. Especially since the BSOD is a Windows 10 BSOD... XP did not have QR code sad face BSODs at the time.
