On October 13, 2025, Microsoft announced a significant expansion of its partnership with the London Stock Exchange Group (LSEG) to integrate LSEG's financial data into Microsoft 365 Copilot and Copilot Studio, enabling advanced AI-driven workflows for financial services professionals. This collaboration aims to enhance decision-making and productivity through secure, AI-ready data integration[1]. Additionally, Microsoft reaffirmed that support for Windows 10 will end on October 14, 2025, meaning no further updates or security fixes will be provided after this date, which could impact millions of users and drive upgrades to Windows 11[2][5]. Despite these major developments, MSFT closed at $514.05 (+0.60%) on October 13, 2025, rebounding from a recent dip and generally tracking broader tech optimism amid a sharp rally in U.S. futures and easing trade tensions.
