The day is finally here: Microsoft has officially ended support for Windows 8.1, which launched almost 10 years ago. 

The end-of-support date—Jan. 10, 2023—means Microsoft will no longer supply security patches or technical support to the operating system, leaving those still running the aging OS vulnerable to potential security threats.   

Also today, Microsoft is ending support for enterprise users on Windows 7. The company officially ended support for Windows 7 for consumers on Jan. 14, 2020. But it gave businesses still reliant on the OS the option to continue receiving security patches for another three years.  

Both operating systems will still function, but without Microsoft’s official support. That means users will have to troubleshoot any problems themselves, and face the risk of computer hacks coming through any unpatched security vulnerabilities. 

For months now, the company has been warning Windows 8.1 users about the end-of-support date through notifications on the OS. The problem is that Microsoft isn’t offering affected consumers a free upgrade path to Windows 10 or Windows 11, which can cost $139. 

Making the issue more complicated is that Windows 11 generally only works on PCs released in the last five years. Hence, all Windows 8.1 devices will likely be ineligible for the upgrade. Meanwhile, support for consumers on Windows 10 is slated to end on Oct. 14, 2025. 

That said, few users will be affected. Market share stats indicate Windows 8.1 only has 0.41% to 2.6% of the OS market. Meanwhile, Windows 7 has a 1.6% to 11% share of the market.

Microsoft created an FAQ for Windows 8.1 users on the end-of-support date. If you stick with the OS, we recommend you back up your files, install an antivirus software, and refrain from logging the device into important online accounts, such as your banks. This should help minimize the impact of any potential hack.

My Experience

I've been a journalist for over 15 years. I got my start as a schools and cities reporter in Kansas City and joined PCMag in 2017, where I cover satellite internet services, cybersecurity, PC hardware, and more. I'm currently based in San Francisco, but previously spent over five years in China, covering the country's technology sector.

Since 2020, I've covered the launch and explosive growth of SpaceX's Starlink satellite internet service, writing 600+ stories on availability and feature launches, but also the regulatory battles over the expansion of satellite constellations, fights with rival providers like AST SpaceMobile and Amazon, and the effort to expand into satellite-based mobile service. I've combed through FCC filings for the latest news and driven to remote corners of California to test Starlink's cellular service.

I also cover cyber threats, from ransomware gangs to the emergence of AI-based malware. In 2024 and 2025, the FTC forced Avast to pay consumers $16.5 million for secretly harvesting and selling their personal information to third-party clients, as revealed in my joint investigation with Motherboard.

I also cover the PC graphics card market. Pandemic-era shortages led me to camp out in front of a Best Buy to get an RTX 3000. I'm now following how the AI-driven memory shortage is impacting the entire consumer electronics market. I'm always eager to learn more, so please jump in the comments with feedback and send me tips.

The Best Tech I've Had:

  • My first video game console: a Nintendo Famicom
  • I loved my Sega Saturn despite PlayStation's popularity.
  • The iPod Video I received as a gift in college
  • Xbox 360 FTW
  • The Galaxy Nexus was the first smartphone I was proud to own.
  • The PC desktop I built in 2013, which still works to this day.
