Organizations are transitioning from Windows 10 to Windows 11, with major companies addressing potential deployment issues. Windows 10 mainstream support ended in October 2025, but users can access the Extended Security Update program for an additional 12 months of coverage. Windows 11 features a refined user interface with a centered taskbar, enhanced visual elements, and productivity tools like snap layouts and Cloud Clipboard. The Start menu has been simplified, and the File Explorer sidebar has been reorganized. Focus Assist is improved with direct settings and integrates with the Windows Clock app. Windows 11 includes Copilot for natural language queries and task automation, with enhanced features for devices with neural processing units. Security is strengthened with Windows Hello and optional integration with Microsoft Defender for Endpoint. The minimum system requirements for Windows 11 include a 1GHz processor, 4GB of RAM, 64GB of storage, and TPM version 2.0. All editions of Windows 11 support encryption and biometric security, with Pro and Enterprise editions offering additional features. Upgrading from Windows 10 to Windows 11 is typically free if the device meets the requirements, with prices for new purchases starting at around £119 for Windows 11 Home and £219 for Windows 11 Pro.
