What is Windows 10 LTSB?
If you’re running critical infrastructure, then Microsoft’s Long-Term Servicing Branch may be the best option for your devices
Patching is one of the most important aspects of running any software on enterprise machines, and Microsoft's Windows operating system (OS) looks to its servicing channels to do this. There are a handful of varying channels that push all kinds of updates, from important security patches to feature updates, to its customers' devices at different speeds.
The Windows Insiders branch releases rougher builds of the Windows OS to users quite frequently, but the Long-Term Servicing Channel (LTSC), by contrast, is the slowest and most stable of these channels.
This manages the updates released to Windows 10 Long-Term Servicing Branch (LTSB) installations, which is designed specifically for a subsection of enterprise users. This iteration is essentially a stripped-back version of the widely-used OS, and doesn't even feature Cortana or Microsoft Edge, as well as a number of popular Windows Apps.
The Semi-Annual Channel' (SAC) releases massive upgrades to users' Windows devices twice a year, while the Windows 10 LTSB branch only updates machines with key security updates - holding back all the bells and whistles. Agreements via the LTSC also last a period of ten years.
This isn't to say new builds of Windows 10 LTSB aren't developed and released, but these aren't pushed to these users automatically in the way that alternative channels may push updates. Windows 10 LTSB users, instead, need external media from which to upgrade their devices.
Windows 10 LTSB vs Enterprise
Windows 10 Enterprise users are the main segment targeted by the LTSB, and it's a particularly niche strand of the Windows 10 family. It's a nearly-completely stripped-back version of Microsoft's flagship OS, and it isn't for everyone; serving a particular purpose in businesses.
In fact, Microsoft says in its user documentation that the LTSC agreement is not intended for deployment to most or all PCs across an organisation, for example, office employees or information and IT workers. This is because of the highly-limited functionality.
Instead, Windows 10 LTSB installations should normally be reserved for special purpose machines, or devices that power critical infrastructure, like ATMs or healthcare equipment. These kinds of devices wouldn't have any need for the additional features Microsoft routinely pushes to Windows 10, and the security patches provided as part of a ten-year LTSC agreement will suffice.
According to official documentation, new LTSC releases are available every two to three years, and organisations can choose to install them as upgrades, or skip the releases entirely over their 10-year agreement. By contrast, Windows 10 Enterprise machines are normally on the SAC release cycle.
What does Windows 10 LTSB feature (or not feature)?
The Windows 10 LTSB Enterprise edition, to give it its full version name, doesn't feature a number of core applications that normally feature in other iterations of Windows 10. The Microsoft Edge browser, for example, is not included, nor is the Cortana virtual assistant. Some limited search capabilities do remain, however.
This is in addition to other omissions, including Microsoft Mail, Calendar, OneNote, Weather, News, Sports, Money, Photos, Camera, Music and the Clock apps. These apps are fundamentally not supported in Windows 10 Enterprise LTSB, even if you install them via sideloading. The Microsoft Store, too, is not included.
What's the latest version of Windows 10 LTSB?
To coincide with its last major upgrade, Microsoft released Windows 10 Enterprise LTSC 2019, or version 1809, in early October 2018. Does this number sound familiar to you? That's because it's the same code assigned to Microsoft's October Update, released at the same time.
Windows 10 Enterprise LTSC 2019 was the first iteration since version 1607 was released in August 2016. However, due to the disastrous handling of the October Update's rollout and several critical bugs found in this Windows 10 version, Microsoft pulled this latest LTSB release, as it did with the consumer version. After re-examining the issues flagged with the latest version of Windows 10, the 2019 LTSB edition was made available again.
This latest version builds on Windows 10 Pro, and adds a range of features designed to address the needs of mid-sized and larger organisations. These include added security features to protect against modern threats, updating and support options, and a comprehensive device and app management system.
