LTSC: What is it, and when should it be used?

Hello M_Lye 

Thanks for engaging, I always appreciate the chance to engage.

You say you "don't use any OS features"?.   Pretty sure this is not actually true, let me explain, and I'll put aside for now the end user innovations and improvements that have been added, that you your users may be missing out on.

1) Are all your PCs the same age, or have your purchased new HW over time? When you do replace, add HW, do you try to acquire the best performance for price at the time its acquired?  If so, your taking advantage to the Windows 10 Silicon policy, where new HW is first enabled on the  current version of Windows 10, and would not be supported for example on the 1607 LTSC release.

2) Do you want/need smaller and  less user intrusive monthly patching?  Those are features that have been and are improved with each Windows 10 update.  Not only are the packet sizes now 80%+ smaller with improved express,  we have improved AI to figure our working hours to install when users are not user their machines, or enable you to manage that for them so that you can stay in compliance with your security, patch requirements, and users can remain productive. You see similar improvements on the Feature update process, where they are both smaller, but off-line time disruption has been reduced from nearly 1 1/2 hours to 20 mins mean time.

3) The combination of staying current with firmware, drivers and OS provides the best security, experience and reliability at any given time. That is the stack that is currently the focus of development and testing by your vendors of choice, ( silicon, oem and os ). Do you stay current with firmware updates and drivers? 

4) The security innovation and capabilities continue to improve and move forward with each release. From things like Windows Info protection to Application Guard, you have much richer tools and better capabilities to address your security needs, again while focusing on user productivity.  

But all that side.  the choice is still yours you can still have (1) , not  use any of the security improvements, enable the new end-user functionality.  You can choose to use LTSC.  While I explained above what it was designed for, customer still choose with version they choose to purchase and use.  

And if you are experiencing a situation where you set a configuration/GP and we over ride it with an update, tell us, tell me, and we will fix it. Certainly we did that a lot in the first 3-4 releases, but that was a big focus  through 1709 to respect  and persist. If and when it happens today, we want to know it and fix it.

Thanks again , and let me know how I can help, with what ever version of Windows 10 you choose to run.
