I'm trying to edit a Windows registry entry to change the key to my Bluetooth device to be able to dual-boot with my Bluetooth keyboard.I know which registry entry to use and I can extract Windows' pairing key by running hex KEYNAME in the chntpw commandline. I open up C:\Windows\System32\Config\SYSTEM with chntpw -e and then can browse and print out the Bluetooth pairing key in hexadecimal.Is there a command which will enable me to edit the Windows registry entry/key in hexadecimal and insert my Bluetooth key from Linux? (See the following Ubuntu forums post to see how to copy the key from Windows to Linux, but I'd like to do it the other way around, I have it paired in Linux and I'd like to copy the key to Windows.) 
Edit a binary value in hexadecimal in chntpw?
