Why we ask you to restart, and how to choose when

Restarting finishes security updates. Here's how to pick a time that suits you, so it doesn't catch you mid-meeting.

Most Windows security updates only finish installing when your computer restarts. Until then, the fix is downloaded but not working. That's why we ask, and why it matters.

Choose a time that suits you

  • Restart now when it's convenient, from the power button in the Start menu, or from Settings > Windows Update.
  • Schedule it from the update notification, or in Settings > Windows Update, for the end of the day.
  • Set your active hours in Settings > Windows Update > Advanced options, so Windows doesn't restart while you're usually working.

Good habits

  1. Restart at least once a week. Choose Restart, not Shut down: shutting down doesn't fully clear things out the way a restart does.
  2. Save your work first. Windows tries to reopen apps, but it can't always recover unsaved changes.
  3. Leave it plugged in at the end of the day if a restart is waiting, so the update can finish.
