So long, Cortana. Microsoft is retiring the voice assistant’s Windows app this month. 

The company is now rolling out an update for some Windows users that effectively disables the Cortana app. The update causes the software to only show a page that says the voice assistant has been “deprecated,” meaning it’s no longer in development and could be retired. 

In an updated support page, Microsoft adds: “Starting in August 2023, we will no longer support Cortana in Windows as a standalone app.” 

The company initially announced it was ending Cortana support for Windows in June. But at the time, Microsoft merely pegged the date to “late 2023.” So it looks like Redmond decided to sunset the software a little sooner than expected. 

It's unlikely many people will mourn Cortana's demise, though. Microsoft originally launched Cortana in 2014 to compete with Apple’s Siri. But after a few years, Microsoft began pulling back investment in Cortana as voice assistant software fell out of vogue. 

Since then, the tech industry has seen a resurgence in chatbots, thanks to the arrival of OpenAI’s ChatGPT. Microsoft is already incorporating the technology through the OpenAI-powered Bing Chat and Windows Copilot, a more advanced AI assistant that the company has started to beta-test for Windows users. Both products, along with Voice access in Windows 11, are also intended to replace Cortana. 

That said, the company’s support document notes Cortana will “continue to be available in Outlook mobile, Teams mobile, Microsoft Teams display, and Microsoft Teams rooms.” It also looks like Microsoft is disabling the Cortana app first for users on Windows preview builds, rather than the stable release. So mainstream users can still use it for a little longer.

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.
