to their computer. This probe is the physical link between a programmer's code and a tiny microchip (like those in smart appliances or medical devices).
This conflict happens because older drivers (frequently dating back to version 2.6.5.0 or around the year 2007) do not comply with modern Microsoft driver security requirements. Modern Windows defenses isolate the kernel memory space to prevent malware from injecting malicious code. If a driver lacks compatibility with HVCI or fails modern digital signature standards, Windows completely blocks Memory Integrity from turning on to shield the OS from potential vulnerabilities.
