Huh? How did you come up with that Build Number?
Are you in reference to the phone or desktop?
There are several reasons WHY one would have a lower build number is because of the Win 7 version they have. In phones, the earliest versions DID have a build number of 6.1 in development; but not the OS Tower --- however, I have seen some laptops with this build number of 6.0 or 6.1 version in Windows 7 lowest edition.
Nevertheless, all of mine are well over the 7.xxx and higher as my Server is SPLIT; so I can run on this desktop on the Win 8 without wrecking havoc on the Win 7 Ultimate if Win 8 crashed.
If you know what you are doing, you can SPLIT your Server (as I have been doing this for years since Win 95 with 286, 386 and 486 Towers - I learned to split or divide them - when piloting or aka testing Win 98 which we know it as "BETA" in today's terminology). I have been splitting my Server into multiple Windows OS for testing but one also needs a heck a lot of TB's and power to run this BETA's today than it was back then and understanding how to run it in BIOS first in order to run which Windows OS you want to run off of.
A price to pay for this hard work; yet, having the back up is imperative as well in event of crash; especially with BETA - RC's.
While I cannot go into further discussion but I have found some detailed information which was disclosed to Microsoft that was very helpful to them as detailed as it was (consider it to be a form of "networking").
It DOES NOT MATTER what type of OS one is going to pick - Win, Mac, IBM, et al... you are always going to run into issues - period. There are no "perfect" and "flawless" computers out there; we wish there were, yet, the goal and desire to create perfection I cannot say isn't unrealistic nor can I say it can't be done either ... for I can say this:
For every pretty lovely Rose you see out there, there are tons of thorns in its way. So true in technology, all these thorn in its sides which hinders the pathways to attain to accomplishments, but one day, it will come to the point where it will become a bud, then a blossming blooming beautiful Rose that everyone would convet over for.
We will get there eventually... in my humble opinion.
