This is Microsoft's master terms of service agreement that governs your use of Microsoft Copilot, Bing, Microsoft 365, Xbox, OneDrive, and dozens of other Microsoft consumer services. The most important thing to know is that if you are a US user and do not opt out of mandatory arbitration within 30 days of your first use, you give up your right to sue Microsoft in court or join a class action lawsuit over disputes. If you want to preserve your right to take Microsoft to court, you must opt out of the arbitration clause in writing within 30 days of first accepting these terms.
Technical Summary
This document is the Microsoft Services Agreement (MSA), a binding contract governing consumer access to Microsoft's suite of services including Copilot, Bing, Microsoft 365, Xbox, OneDrive, and related products, with legal basis in contract law under Washington State jurisdiction and, where applicable, EU/UK consumer protection law. The agreement imposes significant obligations on users including compliance with a detailed Code of Conduct, restrictions on reverse engineering or circumventing service limitations, and acceptance of Microsoft's right to unilaterally modify terms with 30-day notice. Notable provisions include a binding arbitration clause with class action waiver applicable to US users (with a 30-day opt-out window), Microsoft's reservation of the right to suspend or terminate accounts at its sole discretion without prior notice, and broad content licensing rights granted to Microsoft over user-submitted content. The agreement engages GDPR (via incorporation of the Microsoft Privacy Statement and EU-specific addenda), CCPA (California residents retain specific rights), COPPA (services restricted to users 13+ or with parental consent), and the EU AI Act (relevant to Copilot's AI-generated content provisions). Material compliance considerations include the arbitration opt-out deadline, the breadth of Microsoft's content license relative to GDPR's data minimisation principle, and AI-output disclaimer provisions that may conflict with emerging EU AI Act transparency obligations.

Regulatory exposure, material risk, and due diligence action items.
If you live in the US, you cannot sue Microsoft in court or join a class action lawsuit — instead, disputes must go through a private arbitration process with a single arbitrator.
Microsoft can shut down your account or cut off your access to any of its services at any time, for almost any reason, including if Microsoft decides the service is no longer commercially worth providing to you.
When you upload or share content through Microsoft's services, you give Microsoft a broad, worldwide, royalty-free license to use, copy, modify, and share that content across its platforms.
Microsoft warns that Copilot and other AI features may produce inaccurate, harmful, or offensive content, and Microsoft takes no responsibility for how you use that AI-generated content.
Microsoft's services are prohibited for children under 13, and users aged 13-17 must have a parent or guardian's permission and supervision to use the services.
Microsoft limits its financial liability to whatever you paid them in the last 12 months — so if you pay nothing (free tier), Microsoft owes you nothing — and disclaims all implied warranties about service quality or accuracy.
Paid Microsoft subscriptions — such as Microsoft 365 and Xbox Game Pass — automatically renew and charge your payment method unless you cancel before the renewal date.
Microsoft can change its terms of service at any time with notice, and if you keep using the services after the change takes effect, you automatically agree to the new terms — your only alternative is to close your account.
Microsoft prohibits using its services — especially Copilot — to create harmful, illegal, hateful, or misleading content, and violation of these rules can result in immediate account suspension.
