Which of the following is not one of the five mainstream versions of windows 10?

The following versions of Office have been fully tested and are supported on Windows 10. They will still be installed on your computer after the upgrade to Windows 10 is complete.

• Office 365 (Version 16)

• Office 2019 (Version 16)

• Office 2016 (Version 16)

• Office 2013 (Version 15)

Office 2010 (Version 14) and Office 2007 (Version 12) are no longer part of mainstream support. Versions of Office prior to Office 2007 are also no longer supported and may not work on Windows 10.

To upgrade to the latest version of Office, see How do I upgrade Office?

Tips: 

• For peace of mind, we recommend that before you upgrade to Windows 10 you use the Get Windows 10 app to do a compatibility check. Many devices already have the app installed through updates. To see if you already have the app, look for the Windows icon on the far-right side of your taskbar. If you see it, select it to get started.

Windows - General

What is the Lifecycle Policy for Windows?

Windows products are governed by both Modern and Fixed Lifecycle Policies. Search for the product lifecycle for your specific Windows product and its corresponding Lifecycle Policy and end-of-support dates.

What is the difference between a Windows quality update and a Windows feature update?

A Windows quality update is an incremental update to Windows products that includes bug fixes, feature improvements, and security issue resolutions.

A Windows feature update is an update that contains new features. A feature update also includes all previous quality updates, as applicable.

Go here for more information on these terms.

What are the requirements for servicing and updating Windows?

To receive monthly quality updates, customers must be on a supported version of Windows. Go here for support dates.

Windows quality updates are cumulative, with each update built upon the quality updates preceding it.

If I obtained Windows when I purchased a new device, who provides support?

If you have a valid Windows license, you are eligible for support from Microsoft, subject to the Microsoft Lifecycle Policy and the support terms and conditions that were in place at the time of purchase. If you acquired your Windows operating system through the Microsoft Volume Licensing program or from an Original Equipment Manufacturer (OEM), Microsoft offers access to a wealth of online self-help support content in addition to paid technical help offerings. If you acquired your Windows operating system through an OEM, you may also contact your OEM for more information about the support offerings for Windows operating systems from that OEM.

Can I use prior versions of Windows on a device running a newer version?

To use prior versions of Windows on devices currently running a newer version, it is possible for customers to obtain a license for downgrade rights. These downgrade rights will vary depending on whether the software was acquired via Volume Licensing, Original Equipment Manufacturer (OEM), or Full Packaged Product (FPP). To learn more about these rights, review the downgrade rights licensing brief. Prior versions of Windows have limited support when running on new processors and chipsets from manufacturers like Intel, AMD, NVidia, and Qualcomm. For more information, please see Microsoft Lifecycle Policy. A device may not be able to run prior versions of Windows if the device hardware is incompatible, lacks current drivers, or is otherwise outside of the original equipment manufacturer’s (OEM) support period.

When a Windows operating system (OS) reaches the end of its lifecycle or is no longer supported, does that mean new programs will not run on that OS?

Once a Microsoft operating system (OS) reaches the end of support, customers will no longer receive security updates. The OS may still work with programs and hardware after the sale or support of the operating system has been discontinued. However, the possibility increases that new programs and hardware will not be performant on an older OS. This frequently occurs because the manufacturers of new hardware and software make product-design decisions that take advantage of the increased functionality and features in newer operating systems. These manufacturers may decide to discontinue support of their products on older operating systems as appropriate.

Windows 11

What is the servicing timeline for a version (feature update) of Windows 11?

New versions of Windows 11 will be released once per year and will receive monthly quality updates that include security and non-security updates. Customers should always install the latest version before the current version reaches end of servicing to remain supported by Microsoft.

1Home edition does not support the deferral of feature updates and will therefore typically receive a new version of Windows 11 prior to the end-of-servicing date shown.

What are the system requirements for Windows 11?

There are the minimum system requirements for installing Windows 11. Devices that don't meet these requirements might not be able to install Windows 11. Go here for Windows 11 requirements. Note that devices must be running Windows 10, version 2004 or later, to upgrade via Windows Update.

Windows 10

What is the servicing timeline for a version (feature update) of Windows 10?

Historically, new versions of Windows 10 (also called feature updates) were released twice a year via the Semi-Annual Channel. Beginning with Windows 10, version 21H2 (the Windows 10 November 2021 Update), feature updates will be released annually in the second half of the year via the General Availability Channel. Go here to learn more.

Customers should always install the latest version before the current version reaches end of servicing to remain supported by Microsoft.

As of September 6, 2018, we have evolved our servicing timeline for customers who need more time to test and deploy Windows 10 feature updates. Supported versions will be serviced via monthly quality updates.

2Home edition does not support the deferral of feature updates and will therefore typically receive a new version of Windows 10 prior to the end-of-servicing date shown.

3Windows will move to an annual release cadence starting with Windows 10, version 21H2 (the Windows 10 November 2021 Update).

What are my installation options for Windows 10 updates?

It is highly recommended that customers install the latest feature update to stay up to date with the latest security updates, as well as to continue receiving future feature updates, with less impact on IT processes and infrastructure.

To help reduce the burden on network bandwidth, Microsoft designed two different update types: Full and Express3.

If needed, customers may defer Feature Updates via Settings > Windows Update > Advanced options or via an organization's device management policies.

On devices that do not defer the installation of feature updates, the subsequent Semi-Annual Channel or General Availability Channel version of Windows 10 may be automatically offered and installed prior to the end date. Update deferral is not available for all editions of Windows 104. Please see Windows as a Service (WaaS) for information on release channels and the Windows 10 release information page for additional update details.

Not all features in a feature update will be available on all devices. Similarly, a device may not be able to receive updates if the device hardware is incompatible, lacks current drivers, lacks sufficient storage space, or is otherwise outside the original equipment manufacturers (OEM) support period. For more information on compatibility, review the Windows 10 System Requirements as well as the Windows Processor Requirements.

Update availability may vary by country, region, network connectivity, mobile operator (e.g., for cellular-capable devices), or hardware capabilities (including, e.g., free disk space).

3As of April 9th, 2019 Delta Updates are no longer available. To learn more, go here.

4Windows 10 Home does not support the deferral of feature updates and will therefore typically receive a new version of Windows 10 prior to the end-of-servicing date shown.

What happened to the End of Mainstream Support date for Windows 10 listings on the Lifecycle Product Search page?

In the Windows as a Service (WaaS) model, the concept of Mainstream Support does not apply to Semi-Annual Channels, as each Semi-Annual Channel will be serviced (receive monthly quality updates) for a limited time. Customers are required to move to a supported version (feature update) to continue to receive monthly quality updates with security and non-security fixes.

What are the requirements for servicing and updating the Windows 10 Long-Term Servicing Channel (LTSC)?

The Long-Term Servicing Channel (LTSC) is designed to be used only for specialized devices - for example, those that control medical equipment or automated teller machines (ATMs).

To receive monthly quality updates, customers must be on a supported version of Windows 10. Go here for support dates.

See Overview of Windows as a Service (WaaS) for more information on release channels and the Windows 10 release info page for additional update details.

Windows Server

What are the requirements for servicing and updating Windows Server?

To receive monthly quality updates, customers must be on a supported version of Windows Server. Go here for support dates.

Updates are cumulative, with each update built upon the updates that preceded it.

What is the Lifecycle Policy for Windows Server Update Services (WSUS)?

Previously a standalone product, Windows Server Update Services (WSUS) became a component of the Windows Server operating system beginning with Windows Server 2012. A component is defined as a set of files or features that are included with a Microsoft product, whether it is shipped with the product, included in a product service pack or update, or later made available as a web download for the product. As a component, WSUS follows the Lifecycle Policy for the product on which it is installed – Windows Server (the parent product).

Windows 8.1

What is the Lifecycle Policy for Windows 8.1?

Windows 8.1 reached the end of Mainstream Support on January 9, 2018, and will reach end of Extended Support on January 10, 2023. With the general availability of Windows 8.1, customers on Windows 8 had until January 12, 2016, to move to Windows 8.1 to remain supported.

Why were Windows 8 customers required to move to Windows 8.1 two years after the general availability?

Historically, Microsoft has taken a similar support approach related to service packs. When a Windows service pack is released, Microsoft provides customers 24 months of support for the prior service pack or original release. Unlike service packs that are typically a collection of fixes, Windows 8.1 has new features and enhancements, and was designed to give customers the ability to deploy this update similar to service packs. Therefore we are applying the service pack policy to Windows 8.1.

Windows 8.1 does not change any hardware requirements compared with Windows 8 and existing Windows Store apps will work with Windows 8.1. Business customers who had Software Assurance licensing received Windows 8.1 as a free update.

Windows Embedded

How does the end of support for Windows XP impact Windows Embedded products?

Windows Embedded products have their own distinct lifecycles, based on when the product was released and made generally available. It is important for businesses to understand the support implications for these products to ensure that systems remain up-to-date and secure. The following Windows Embedded products are based on Windows XP:

• Windows XP Professional for Embedded Systems. This product is identical to Windows XP, and Extended Support ended on April 8, 2014.

• Windows XP Embedded Service Pack 3 (SP3). This is the original toolkit and componentized version of Windows XP. It was originally released in 2002, and Extended Support ended on January 12, 2016.

• Windows Embedded for Point of Service SP3. This product is for use in point of sale devices. It's built from Windows XP Embedded. It was originally released in 2005, and Extended Support ended on April 12, 2016.

• Windows Embedded Standard 2009. This product is an updated release of the toolkit and componentized version of Windows XP. It was originally released in 2008, and Extended Support ended on January 8, 2019.

• Windows Embedded POSReady 2009. This product for point of sale devices reflects the updates available in Windows Embedded Standard 2009. It was originally released on 2009, and extended support ended on April 9, 2019.

Why does support for Windows XP Professional for Embedded Systems end with Windows XP?

Windows XP Professional for Embedded Systems is a specially licensed version of Windows XP Professional for industry devices, delivering the full features and functionality of Windows XP. Given this relationship, both operating systems followed the same release schedule and share the same timeline.

Why was Windows XP Embedded be supported for two years longer than Windows XP Professional for Embedded Systems?

XP Embedded is a modular form of Windows XP, with additional functionality to support the needs of industry devices. It was released separately from Windows XP and provides a separate support lifecycle to address the unique needs of industry devices. Devices running Windows XP Embedded reached end of support in 2016.

What is the Lifecycle Policy for Windows Embedded 8.1 products?

Windows Embedded 8.1 falls under the same lifecycle policy as Windows Embedded 8 with support ending 7/11/2023. Customers have 24 months to move to Windows Embedded 8.1 to remain supported. This applies to Windows Embedded 8 Industry Enterprise and Industry Pro.

What is the difference in the Extended Support phase for Windows Embedded products versus regular Windows products?

The type of support provided in the Extended Support phase is consistent across all products. Critical security updates are made available for products until the published Extended Support end date. This allows businesses to ensure that they are up to date in protection against security attacks. Similar to Windows products, Embedded products also receive updates through Microsoft Update. No regular updates are being released for Windows Embedded products to the release channels of DPC (Device Partner Center), Windows Embedded Developer Update (WEDU) and Microsoft OEM Online (MOO).

Windows Silicon Policy

What is the Windows policy for silicon support?

Windows products will be supported for security, reliability, and compatibility on the latest silicon available at the time of release. This includes previous silicon generations still in support by the Original Equipment Manufacturer (OEM).

What is the Windows Lifecycle policy for Intel's sixth generation of processors (also known as Skylake) released in late 2015?

Windows 7 and 8.1 Devices Supported Skylake devices will receive applicable Windows security updates through the end of support. These systems should be upgraded to Windows 10 to continue receiving support after the period ends. Search here to see your product's end of support dates.

Windows Embedded 7, 8, and 8.1 Skylake devices running Windows Embedded 7, 8, and 8.1 will be supported according to the lifecycle support policy for those products. During this supported period, these systems should be upgraded to Windows 10 to continue receiving support after the period ends. There is no supported device list for Windows Embedded.

Windows Server The Windows Server platform is supported on certified or logoed hardware as listed in the Windows Server Catalog. Today, you can browse the catalog and find hardware that meets or exceeds our minimum server hardware requirements and has been successfully certified for supported Windows Server products. For Windows Server, the policy consists of five years of mainstream support followed by five years of extended support. This lifecycle impacts the timeframe for which new devices and systems can be certified. We allow new systems to be submitted for certification up to the point when the OS transitions to extended support.
