Windows Server (formerly Windows NT Server) is a group of operating systems (OS) for servers by
Microsoft. The brand name was changed to Windows Server in 2003.

Servicing channels
There have been historically three primary release channels available:
- Long-Term Servicing Channel (LTSC)
- Semi-Annual Channel (SAC)
- Annual Channel (AC)
The Windows Server Semi-Annual Channel (SAC) was retired on August 9, 2022. There will be no future SAC releases of Windows Server.
The Windows Server Annual Channel (AC) was released after the retirement of the Semi-Annual Channel (SAC). The first release of the Annual Channel (AC) was on October 24, 2023.
Long-Term Servicing Channel (LTSC)
With the Long-Term Servicing Channel, a new major version of Windows Server is released every 2-3 years. Users are entitled to 5 years of mainstream support and 5 years of extended support. The Long-Term Servicing Channel will continue to receive security and non-security updates, but it will not receive the new features and functionality.
Semi-Annual Channel (SAC)
Each release in this channel is supported for 18 months from the initial release. Most of the features introduced in the Semi-Annual Channel have been rolled up into the next Long-Term Servicing Channel release of Windows Server.
In this model, Windows Server releases were identified by the year and month of release: for example, in 2017, a release in the 9th month (September) would be identified as version 1709. Fresh releases of Windows Server in the Semi-Annual Channel occurred twice each year. The support lifecycle for each release is 18 months. Starting with fall 2020 (20H2) releases, the identification changed. Instead of a month, the release is named based on the release cycle. For example: version 20H2, for a release in the second half of the year 2020.
Annual Channel (AC)
Similar to Semi-Annual Channel (SAC), but releases occurred every 12 months.
The support lifecycle for each release is 18 months of mainstream support, plus 6 months of extended support.
Extended Security Updates (ESU)
For some releases, customers also have the option to purchase Extended Security Updates (ESU).
It includes Critical and/or Important security updates for a maximum of three years after the
product’s End of Extended Support date. Customers can also get technical support for the ESU period
as long as they also have an active support plan.
More information is available on the Microsoft Windows Server website.
You should be running one of the supported release numbers listed above in the rightmost column.

The support for Windows Server 2016 has ended. This means, that the server will not be getting any updates anymore, no improvements and no bug fixes after the support end data. In this blog you can read more about the end date of the support, and the solutions on this.
Is Windows Server 2016 still supported?
The Windows Server 2016 support end date was on 11-01-2022. Users can still rely on the extended support until the 11-01-2027. This means that if you still use Windows Server 2016 you will be receiving security updates until that date but no bug fixes and other improvements.
Alternatives for Windows Server 2016
If you are using Windows Server 2016, you might be thinking about other aspects that have ended with the mainstream support. Theoretically, you can keep using the license, however, in the case of a (big) bug, for example, Microsoft would not fix it anymore. Therefore, it could be smart to look for an alternative for Windows Server 2016, when the extended support end date comes closer.
The most intuitive alternatives for Windows Server 2016 are Windows Server 2019 and Windows Server 2022. These are the newer versions, with more and improved features compared to the 2016 version. You can read more about the differences between the Windows Server 2019 and the 2022 versions below.
Windows Server 2019 vs. 2022
In the table underneath, you can see the differences between Windows Server 2019 and 2022. Based on the information below you can compare the two and decide to which one you would want to upgrade. The Server you should choose heavily depends on the cores you need. Another aspect you should take into account are the new functions to each edition. The mainstream support end date for the 2019 version expires on 9-1-2024. Windows Server 2022 will have mainstream support until the 13-10-2026.
Windows Server 2016 to 2019/2022 upgrade
You can upgrade your Windows 2016 Server to either one of 2019 or 2022 Windows Server. This means you will be receiving bug fixes and improvements for a longer time. Now you are probably wondering: how can I upgrade my Windows 2016 Server to a newer version? The answer is in the following 9 steps:
- First, you need to buy a license for the Windows Server you want. You can take a look at our product range for Windows servers here.
- Once you have received the license key, you can install it. The first step here, is to choose the installation language, the time zone and the keyboard layout you are using, for example QWERTY. After that, you have to click on ‘install now’.
- Select the version you just bought and want to install, and click next.
- The license terms will pop up on your screen. Read through them, and accept them to continue the installation process of Windows Server.
- At the screen with the type of installation you have to press ‘upgrade’ if you already have an older version. If this is the first installation, you press the custom button.
- The next step is to choose the the server’s location of installation. You can create a new one here and click next.
- After that, the installation should start, and you have to wait until it is installed.
- Choose a password, and make sure you can remember it, write it down somewhere for example.
- The final step is to complete the installation by clicking the ‘finish’ button.
Buy Windows Server 2019 or Windows Server 2022:

Microsoft Windows Server 2016 was released in September 2016. So, when does it become end-of-life? There is a lot of false information about the EOL status of Windows Server 2016. We review the EOL status and what it means for the Windows Server 2016 administrator.
Windows Server 2016 follows the Fixed Lifecycle Licensing Policy. So, support for Microsoft Windows Server 2016 is slit into 2 halves. Each Fixed Lifecyle product of Microsoft comes with 2 different support:
- Mainstream support
- Extended support
Mainstream support is valid for 5 years from the release data. And, Extended support is valid for the successive 5 years once the mainstream support ends.
With a release data of September 2016, we now understand that the mainstream support for Windows Server 2016 is valid for the first 5 years. And, the successive 5 years of support will be called the Extended Support.
There is a difference in the scope of Mainstream support and Extended Support. So, we need to understand those differences to appreciate the Fixed Lifecycle Plan.
It may be pertinent to understand that Extended Support of a Fixed Lifecycle product is different that the ESU or Extended Security Updates programs.
So, for Windows Server 2016, the mainstream support ended on 11 January, 2022. The Extended Support for Windows Server 2016 will end on 12 January, 2027.
The question of the ESU program for Windows Server 2016 will be relevant after January 2027. So, there is no need to commit into buying any ESU for Windows Server 2016 until January 2027.
What does the Mainstream support mean?
The mainstream support for Windows Server 2016 ended in January 2022.
Mainstream Support is the first phase of the product lifecycle. At the supported service pack level, Mainstream Support for Windows Server 2016 includes:
- Incident support (no-charge incident support, paid incident support, support charged on an hourly basis, support for warranty claims)
- Security update support
- The ability to request non-security updates
For Windows Server 2016, the mainstream support ended in January 2022. So, we can conclude that product support for Windows Server 2016 in terms of feature updates and non-security updates will no longer be offered.
Thankfully, access to security updates for Windows Server 2016 is covered under the ‘Extended Support’.
What does Extended Support for Windows Server 2016 mean?
Extended Support for Windows Server 2016 begins after the mainstream support for the server ended in January 2022. Until 12 January 2027, Windows Server 2016 is eligible for Extended Support.
The Extended Support for Windows Server 2016 include the following:
- Security Updates to patch security vulnerabilities reported in Microsoft security bulletins.
Product support for Windows Server 2016 is not included in the Extended Support.
You can always buy a Service Pack for Windows Server 2016 to enjoy support for the product. But, for any product issues requiring Microsoft support, you will need to pay to get that support separately.
Extended Support for Windows Server 2016 started in January 2022 and will end in January 2027.
Security coverage for Windows Server 2016
So, the coverage for providing security updates for Windows Server 2016 includes a 10 year period that is comprised of 5 years of Mainstream support and 5 years of Extended support.
The ‘Patch Tuesday’ program for Windows Server 2016 will offer security updates for the server until January 2027. Post January 2027, you will need to enroll in the paid subscription program of the ESU program for Windows Server 2016.

- When Is Windows Server 2016 End of Life? How to Upgrade?
By Vera | Follow |
Last Updated
What is the end of life for Windows Server 2016? How can you upgrade to Server 2022 after Server 2016 EOL? In this post, MiniTool will tell you answers to these questions and countermeasures. Now, let’s have a look.
Windows Server 2016 End of Life
Server 2016 is the eighth release of the Microsoft Windows Server operating system and it was developed along with Windows 10. On October 1, 2014, its first preview version appeared. On Sep 26, 2016, Server 2016 was released and then broadly released for retail sale on Oct 12, 2016.
Now Windows Server 2022 has come for several years, and then you may ask: is Windows Server 2016 end of support? Generally, each operating system has its lifecycle. Speaking of Server 2016 end of life, Microsoft ended its Mainstream Support on Jan 11, 2022.
After that date, the system won’t receive some updates but security updates are still available. Besides, Server 2016 won’t receive any bug fixes or improvements.
But after the Mainstream end date, you can choose to purchase Extended Security Update (ESU) to gain Extended Support which is usually 5 years. When it comes to “Windows Server 2016 end of life extended support”, its end date refers to Jan 12, 2027. That is, the final Server 2016 EOL lasts until Jan 12, 2027.
The two dates here apply to these editions of the Server system, including Datacenter, Essentials, MultiPoint Premium, and Standard.
Upgrade to Windows Server 2022 from 2016
As this operating system ages, it is liable to virus attacks or other malicious software from cybercriminals. Eventually, manufacturers cannot patch and update the old system because of outdated architecture. So to protect your data from various attacks and prevent data loss, upgrade your Windows Server 2016 to 2022 after Server 2016 end of life.
Back up Files in Server
Before the update, we recommend you to back up your important files in Server 2016 since you may run into some update issues or errors, leading to data loss. To prevent file loss, run the backup software – MiniTool ShadowMaker for data backup. Besides, if you use an ISO file to perform a clean install of the Server system, we also advise you to backup files since this installation process can erase your C drive including files saved in it.
MiniTool ShadowMaker enables you to easily backup files, folders, disks, partitions, and Windows, and its Trial Edition can work well in Windows 11/10/8/8.1/7 and Windows Server 2022/2019/2016/2012/2008. Now, download and install it on your Server 2016 for data backup.

Step 1: Launch MiniTool ShadowMaker Trial Edition and connect a USB drive or external hard drive to the PC.
Step 2: Go to Backup > SOURCE > Folders and Files, choose files to back up, and click OK.
Step 3: In Backup, click SOURCE to choose an external drive or USB drive.
Step 4: Click Back Up Now to begin file backup.
How to Upgrade to Server 2022 After Windows Server End of Life
After the backup, now you can choose to upgrade to Windows Server 2022 and here we take an in-place upgrade as an example:
Step 1: Download Windows Server 2022 ISO and save it on the Desktop.
Step 2: Right-click on the ISO and choose Mount.
Step 3: Double-click on the setup.exe file and then the Windows Server Setup window opens. Tap on Next to continue.
Step 4: Choose an edition of Windows Server 2022.
Step 5: Finish the update by following the on-screen instructions.

Final Words
In light of Windows Server 2016 end of life (EOL), you should take action to upgrade to an up-to-date version. To keep data safe, you had better back up crucial files before the update. Besides, if the PC is not suitable for the upgrade, it is also essential to back up data to safeguard against data loss or corruption resulting from system crashes using MiniTool ShadowMaker.
