Microsoft is ending extended support for Windows 7 on January 14th 2020. With Windows 7 reaching it’s end of life, I highly recommend that you start planning your upgrade from Windows 7 to Windows 10.
When support ends, no more security patches or Windows updates will be available for the product. Expect numerous zero-day exploits to be released shortly after the product reaches EoL.
- Test all your applications (line of business applications) compatibility with Windows 10 before deploying
- Test the OS compatibility on your infrastructure (example, SBS Small Business Server requires modification to support Windows 8 and Windows 10 properly)
- Compare man-hours and support costs for an upgrade vs the cost of new computers which come pre-installed with Windows 10
