Windows 10 Support Ended: What Still Works and What to Do
Windows 10 still starts after October 14, 2025, but Microsoft no longer provides normal security updates, software updates or technical support.
Timeline
- October 14, 2025: Microsoft ended support for Windows 10.
- After support ended: Windows 10 continued to function but stopped receiving normal security and feature updates.
- Post-support options: Eligible users can move to Windows 11, use an available extended-security program, replace the device or use another supported operating system.
Microsoft ended support for Windows 10 on October 14, 2025. A Windows 10 PC did not suddenly stop working on that date. The operating system can still start and installed applications may continue running, but Microsoft no longer supplies the normal stream of security fixes, feature updates or technical support. [1]
The main risk grows over time: newly discovered vulnerabilities may remain unpatched on a standard Windows 10 installation. Antivirus software can block some threats, but it cannot replace operating-system security updates. A browser or application can also end its own Windows 10 support on a different schedule. [1][2]
The preferred Microsoft path is an upgrade to Windows 11 on compatible hardware. Compatibility depends on requirements including a supported processor, TPM 2.0, Secure Boot capability, memory and storage. PC Health Check can help, but a user should back up important files before any operating-system upgrade. [1]
A computer that does not qualify for Windows 11 can be replaced, enrolled in an available Extended Security Updates program, or moved to another supported operating system if the owner is comfortable doing so. Extended security updates are time-limited and focus on important security fixes; they do not restore full Windows 10 development. [1]
Microsoft 365 and individual applications have their own support timelines. Continued application updates do not mean the underlying operating system is supported. Likewise, an application ending support does not by itself disable Windows. Users should check both the operating-system lifecycle and the critical applications they rely on. [1][2]
Before choosing, make an inventory of the device, its Windows edition, hardware compatibility, required applications and backup status. For a work or school computer, the organization’s IT policy controls the decision. Installing Windows 11 on unsupported hardware can create future update and reliability problems. [1][2]
For a device kept temporarily on Windows 10, reduce exposure while planning the transition: install every available final update, maintain tested backups, remove unused software, use a supported browser where available and avoid treating the machine as a safe long-term platform for sensitive work. These steps lower some risk but do not convert an unsupported operating system back into a supported one. [1][2]
