When Microsoft releases a product, it often provides information about that product’s supported lifespan. The final stage of a product’s lifecycle is “end of extended support”. All Microsoft products eventually reach this stage of life. For example, Microsoft has posted end of extended support dates for even relatively new products like Windows 8.1 and Windows Server 2012 R2. In the case of Windows Server 2012 R2, end of extended support is 10th January 2023. When a product reaches end of extended support, Microsoft will no longer publicly release software updates, patches, hotfixes, technical advice, service packs, or documentation related to that product.
