Event ID 7026 and i8042prt is a recurring error in the Windows Event Logs. I usually see this error on a server reboot .
It’s normal for a server to not have a keyboard or mouse attached. I usually suppress the error , by creating a headless entry.
The errors occurs if you don’t plug in a PS/2 keyboard – which causes the drivers to not move to SYSTEM32\DRIVERS
