Microsoft is investigating a known issue affecting the new Chromium-based Edge browser where the app is automatically launching itself on Windows startup even if users haven't configured it to auto-start after their systems boot up.

"We've heard from our community that some versions of Microsoft Edge are automatically launching whenever users start their PCs and log into Windows, regardless of their selection in edge://settings/onStartup," Microsoft community manager Fawkes Serafinski said.
