    I am or was still having trouble getting my computer to activate Windows 10, however now the computer will not even boot. I had looked everywhere I could think of and could not find the original activation code. However, I did find out that on a Dell XPS, the code is build into the BIOS, and some of the messages I get from Windows tell me that the last 5 digits of my number are ZYT43. I am using my other Dell XPS machine and will put a call in for Product Service from Dell. If it won’t boot, no telling what is the problem.
