On October 14, 2025, Microsoft will officially end mainstream support for Windows 10. Customers will be required to either purchase Microsoft’s Extended Security Updates (ESU) for their Windows 10 assets; move to Windows 11 or another OS; take a different approach to providing application and data access to users such as thin-client with virtual desktop infrastructure (VDI), bring your own device (BYOD), or browser-only access; or secure existing Windows 10 assets in a manner that will reduce the risk of compromise on these unsupported desktops. This report will provide guidance to assist IT and security decision-makers in making informed decisions about handling the end of Windows 10.
