On October 14, 2025, Microsoft officially ends support for Windows 10, Office 2016 and 2019, Exchange Server 2016 and 2019, and several other major products, marking a significant transition for enterprise and consumer customers. After this date, these products will no longer receive security updates, bug fixes, or technical support, prompting organizations and individuals to upgrade to Windows 11 and newer Microsoft offerings[1][4][5]. This milestone is widely covered in official Microsoft communications and industry news, but there are no reports of additional company-specific events or earnings announcements on this date. The last available MSFT stock price was $513.54 (-0.10%), reflecting a stable market response ahead of this planned lifecycle event, with no evidence of a significant price move directly attributed to the end-of-support announcement.
