Overview of Upcoming Windows Versions for Music Servers

Recommended Posts

Since both Windows 10 Enterprise LTSC 2021 and Windows 11 21H2 should be coming soon, let's take a look at what to be expected in the (near) future.


(Previously another thread about LTSC was also created on this forum, therefore I'd like to stick with the same forum as well.)



First of all, basically "plain vanilla" LTSC and IoT Enterprise LTSC should be identical to each other while the only difference should be the licensing terms etc.




Windows 10 IoT Enterprise shares all the benefits of the worldwide Windows ecosystem. It is a binary equivalent to Windows 10 Enterprise, so you can use the same familiar development and management tools as client PCs and laptops.

What is Windows IoT Enterprise LTSC 2021? | Microsoft



What’s New in Windows 10 IoT Enterprise LTSC 2021 - Embedded Computing Design




And then here's why we're going for that particular version of Windows 10 in the first place




2) The noise signature of OS has a huge influence over the sound that comes out from the system. Windows LTSC is the clear leader in Emile's testing, and the gap between the latest from Microsoft and the different flavors of Linux can only be expected to increase in the future. When Microsoft delivers a better kernal and scheduler, Emile for sure will build an updated OS from these new components. So the OS is absolutely future obsolescence proof for many years to come




c) That's a lot of trial and error, we do take a different approach, we start out with Windows 10 IoT Enterprise LTSC which is a stripped down version of Windows for devices requiring stable performance over time, like cash registers, industrial appliances etc. It is only available to OEM system builders. This is actually a lighter weight system then Windows Server "out of the box", but we do subsequently modify it, this is quite common for OEM system builders and there are a wide range of tools available to do so. A lof of components we do not need for music playback cannot be removed or disabled after Windows has been installed, so we remove them from the installation media before they are installed. Do be prepared to allocate considerable time before attempting this yourself as removing something can lead to all sorts of unpredictable results. Our current software installation probably took hundreds of reinstalls to get where we are now. A faster way is to look around on GitHub, where several people have shared scripts to create a stripped windows installation media, do read the feedback first if these are operating reliably.




Emile, which license do you use for the Windows 10 Enterprise LTSC? Is it the “Windows 10 IoT Enterprise 2019 LTSC High-End?”



We have an OEM volume license with a slightly different description but I expect the software itself to be similar if not the same.



(I certainly don't recommend anyone to install this "Xtreme LiteOS 11" stuff for obvious reasons, we could end up losing the shirt or something if they're throwing malware / ransomware etc. into the mix.)


So I'm just talking about this (unofficial for sure) Xtreme LiteOS 11 as a proof of concept, apparently its footprint should be quite impressive to say the least

  • Superlite = just under 4.8GB
  • Barebone = just under 4.5GB

Even the CPU usage turned out to be significantly lower as shown below



So how do we do it then? We could either pay for NTLite or just use some freebies instead

Windows LTSC Guide

I have been putting some notes on this but haven't worked actively. I wanted to get the new chassis first, so I can start from scratch and document everything I do that makes a positive difference. I don't want to make any changes to my Windows, especially while using it to voice the power supply. 





















(All of them should be able to support Windows 10 while YMMV with Windows 11.)



Now where do we get the latest build of Windows 11 since it ain't really going RTM yet? The semi-official way is called UUP (Unified Update Platform) as mentioned below








Personally I don't feel like going through all that technical stuff about UUP but IMHO it's still necessary to show that we're actually downloading those files from Microsoft





Let's ping that server uupdump.sf.tlu.dl.delivery.mp.microsoft.com


C:\>ping -n 1 uupdump.sf.tlu.dl.delivery.mp.microsoft.com

Pinging sni1gl.wpc.nucdn.net [] with 32 bytes of data:
Reply from bytes=32 time=37ms TTL=57

Ping statistics for
    Packets: Sent = 1, Received = 1, Lost = 0 (0% loss),
Approximate round trip times in milli-seconds:
    Minimum = 37ms, Maximum = 37ms, Average = 37ms


And then ping sni1gl.wpc.nucdn.net


C:\>ping -n 1 sni1gl.wpc.nucdn.net

Pinging sni1gl.wpc.nucdn.net [] with 32 bytes of data:
Reply from bytes=32 time=36ms TTL=57

Ping statistics for
    Packets: Sent = 1, Received = 1, Lost = 0 (0% loss),
Approximate round trip times in milli-seconds:
    Minimum = 36ms, Maximum = 36ms, Average = 36ms


Both of them were returning the same pair of matching IP addresses, though most likely you'll get a different pair on your side since that's gonna be based on your own physical location.


sni1gl.wpc.nucdn.net could also be found here






nslookup uupdump.sf.tlu.dl.delivery.mp.microsoft.com

I hope that's more than enough to demonstrate what "UUP dump" is actually doing in the first place, it's always downloading files directly from the servers of Microsoft.


Here are some instructions





I'm not posting any links to either site, though it's pretty easy to DAFS and then get build 22000.132 / 22000.160 etc. ourselves





If we weren't exactly happy about jumping through all the hoops, we could consider joining their Windows Insider Program instead

Alternatively, we could go for an existing version of IoT Enterprise LTSC instead

AMA: Windows 11 and Windows 10 servicing & lifecycle



“We announced the next Windows LTSC would be built on Windows 10, version 21H2, and yes it will be a 5 year support lifecycle. We can expect that the next LTSC *after* Windows 10 Enterprise LTSC 2021 will be built on Windows 11. And it will also keep the 5 year support. However, that’s expected in 3 years or so, so anything can happen in that timeframe. If you need to use LTSC for a longer period, we recommend moving to Windows 10 IoT LTSC.”







About 150 bucks for the 2019 version, though it might be a good idea to wait until the 2021 version is available

After that I purchased an LTSC high-end license which was required since I am running a Ryzen 3700.  They have to mail the license to you since the CLA agreement requires you to put a sticker on the case.


Cost was about $150 in total.
