Microsoft has issued a warning to the 240 million Windows users still on Windows 10 that they will lose all security support for their PCs, urging them to upgrade to a secure Windows 11 PC, preferably the Copilot+ PC. While 500 million Windows 10 users can upgrade to Windows 11 for free, many face the choice of buying new hardware or operating without security updates. The deadline for Windows 10 support is set for October 14, 2025. Microsoft has been using full-screen pop-ups to encourage users to reconsider their setups, as only 20 million users engage with Copilot weekly compared to 400 million using ChatGPT. Despite this, Microsoft claims strong early reception for Copilot+ PCs, with 15% of premium laptops sold in the U.S. during the holiday quarter being Copilot+ models. A feature called Recall, which tracks user activity, raises privacy concerns for those considering the upgrade.
