As soon as Windows 10 is no longer supported, the desktop app of OneNote will stop working. The Windows 10 version will no longer receive updates or bug fixes, which may lead to potential performance issues and reduced functionality, Microsoft warns. You will also lose the ability to sync notes with the web version or label and secure sensitive information.
Switch Now
Microsoft urges OneNote users to fully switch to Windows 11 or the 365 web version of the note-taking app now. “OneNote on Windows (OneNote M365) is the future of OneNote, with ongoing investments in AI features like Copilot to increase productivity,” Microsoft writes in the announcement.
Those who want to wait until the last day will be reminded of the deadline in increasingly less subtle ways. From June, Microsoft will slow down the synchronization speed between Windows 10 and the web version, and from July, you will see banners: a trick that Microsoft likes to apply to promote Windows 11. According to Microsoft, it’s also better to remove the legacy application once you no longer use it.
Microsoft leaves no doubt that the end of Windows 10 is near. Millions of PC users will sooner or later have to give in and install Windows 11 or buy a new PC. If you want to continue using Windows 10 after October despite the warnings, follow these tips to keep your PC safe.
