Hi Carl,
Thanks for your post. Based on my research, we have experienced similar issue that is because it's Fn + ESC to lock 2nd function, basically reversing the function itself. Can you check if Fn + ESC works for you?
If not, generally speaking, this setting is normally in your BIOS, rather than in Windows Shut your system down When your system starts, on the manufacturers logo, you should see text like 'Press F2 to enter setup', it may be another key like DEL, F11, etc. Once in BIOS, look for Function key settings, you should see something like FN key emulation. Then try to change that setting and see if it can resolve this issue.
Best Regards,
Ian Xue
