Windows will directly download and install updates once a day for you.
If automatic updates aren't functioning there might be a problem with your computer:
- Repair a problem with Microsoft Windows Update
- Reset the Windows Update components
- Some malware or viruses can turn off Microsoft Update.
You can also force a download of the newest daily update. This is the same as when Microsoft Windows directly downloads the update, and can be effective if you aren't connected to the Internet or haven't turned your computer on for a few days.
Because these updates are changing once a day, the definition version might be contrasting to what is shown on this page, even after you have clicked the Update button.
Commonly, updating once a day offers you a good level of security, and it limits us from continually updating your software and interfering with how you use your computer.
Every now and then you might want to update more often. This can be beneficial if you have some hard to remove malware, Microsoft Windows update isn't working correctly, or you aren't connected to the Internet.
- This package allows you to manually update Microsoft Security Essentials.
- The updates can be easily installed.
