During Windows migration projects or license negotiations, companies repeatedly face the question of exactly how they will benefit from extending Software Assurance (SA) for Windows 10. So what are the actual advantages and what consequences may there be in the event that SA for Windows 10 is discontinued?
Microsoft made a few changes to the licensing of available versions when it rolled out Windows 10. The Microsoft Desktop Optimization Pack (MDOP) became an integral part of the Windows Enterprise SA benefits and is therefore no longer available as an add-on to purchase from this version on. The classic Enterprise version was turned into Windows 10 Enterprise E3. The company also launched Windows 10 Enterprise E5, Windows 10 LTSB and other versions. I’ll use this article to take a look at Windows 10 Enterprise LTSB without active Software Assurance.
First up, let’s define a term: Microsoft introduced three ways of releasing updates during the rollout of Windows 10: Current Branch (CB), Current Branch for Business (CBB) and LTSB. LTSB stands for “Long Term Servicing Branch” and is equivalent to the LTS versions of Linux.
Microsoft describes the types of releases as follows:
In this regard, Microsoft announced on April 20, 2017 that larger upgrades with new features like the “Creators Update” will be rolled out twice a year in March and September. This procedure applies also to Office 365 ProPlus version. Click here for further information.
Cases in which Windows 10 Enterprise with Software Assurance was purchased as part of a Microsoft Agreement, but the SA was not extended, will impact the deployed Windows 10 Enterprise version as well. When SA is discontinued, customers are only entitled to use Windows 10 Enterprise LTSB. The implications are as follows:
If Software Assurance (SA) is not extended, companies that acquired the right during the contract term to install Windows 10 will only be entitled to roll out Windows 10 LTSB.
Once Software Assurance for Windows 10 Enterprise (E3/E5) comes to an end, customers have a 90-day grace period to switch their current installation to Windows 10 Enterprise LTSB. To do this, they need to uninstall their Windows 10 Enterprise (E3/ E5) version and then deploy Windows 10 LTSB. This procedure is necessitated by the very significant differences between this version and Windows E3/ E5, which make reinstallation unavoidable.
A distinction is made between Windows 10 Enterprise LTSB with or without active Software Assurance. Only the current Windows 10 LTSB version may be used if there is no SA. This has the following consequences:
Windows 10 Enterprise LTSB supports only the hardware available upon release. This means that a new LTSB version must be deployed, i.e. purchased, for later hardware generations in the event that Software Assurance was not agreed.
Compared to E3/E5 versions, Microsoft 10 Enterprise LTSB provides only a basic set of features. For instance, it doesn’t come with functions that may be important to quite a few companies:
The following table illustrates the differences to Windows 10 E3/E5 in terms of the scope of features:
Companies using Windows 10 with Software Assurance have the option to deploy Windows 10 LTSB with the latest LTSB version, instead of being stuck with just one version.
Using Windows 10 LTSB as the standard client may seem worthwhile to companies at first glance, as Microsoft does not provide this version with a steady stream of feature updates. Initially this may seem like a good thing. But if one considers the restricted scope of features compared to the E3 and E5 versions, choosing this path may already be a dead end at this point. What’s more, companies tend to replace their hardware in rolling cycles and have defined a particular standard client. The aim is to implement plannable rollouts over a timeframe of years. In this case, though, Windows 10 LTSB (without SA) will not support future hardware. But if the hardware is not supported, companies will be forced to purchase more recent versions. So depending on the term of the current Windows version, discontinuing SA would not be justifiable from an economic perspective alone.
Apart from this, adopting and then abandoning Windows 10 LTSB will always necessitate reinstallation of the Windows version and the associated workload. It is therefore easy to understand why Microsoft recommends using Windows 10 LTSB only for special systems, and not deploying it in the elevated role of a standard client.
