Microsoft Windows 10 (64-bit)

I have replaced the motherboard on a machine. I have updated all the bios info, except for the featurebyte field.  I have tried several methods to enter the information, however it always returns  CRC Invalid

 

This is what I have: 

 

2U2E 3X47 5K67 6J6S 6b7B 7H7M 7Q7T 7W7a 7map aqb3 bhbm dufy .N4

 

I have tried with spaces, without.  added an extra space after the .N4. 

 

I have seen a note where the system only takes 40 characters, is that accurrate?

 

Is there a proper method to enter this?
