Support for Windows 10 has now ended as of October 14. Here's everything you need to know about how your PC is at risk, and what you can do to remain secure.

In what marks the end of an era, Microsoft has released the Windows 10 KB5066791 cumulative update, the final free update for the operating system as it reaches the end of its support lifecycle.

Hundreds of millions of PCs are still running Windows 10, and even with extended security updates, the population of unpatched PCs will spike over the next few years. How bad can it get?

The tech giant has rolled out fixes for 173 CVEs, including five critical-severity security defects. Microsoft on Tuesday announced the release of patches for 173 unique CVEs in its products, including two flaws that have been exploited in the wild. Patches were also released for 21 non-Microsoft CVEs.
