Microsoft Windows will directly download and install updates for your Microsoft security program. You don't need to do anything, and you will receive a new update once a day if your PC is frequently connected to the Internet.
If automatic updates aren't working there might be a problem with your computer:
- Fix a problem with Microsoft Windows Update
- Reset Windows Update components
Some viruses can turn off Microsoft Update. In this case you might want to work with Microsoft Safety Scanner or, for more obstinate viruses, Windows Defender Offline.
You also have the possibility to force Microsoft Windows or your other programs to download and install the latest release of the daily update. This works exactly the same as when Microsoft Windows automatically downloads the update, and can be effective if you aren't constantly connected to the Internet or you haven't used your computer on for a few days.
If you want the absolutely latest updates, you can manually download and install them.

Install the latest Windows Defender definition updates and make sure your computer is safe from viruses, spyware and other malware at all times
Running any signature-based antivirus without the latest definitions might lead to serious security-related problems. Unless the latest virus definitions are installed, the anti-malware tool might fail in detecting some recent threats, which could lead to data theft and a compromised system.
If you rely on Windows Defender to protect your computer against malware, it is advisable you run definition update on a daily basis. However, there are situations when this is not possible, such as when the PC is no longer connected to the Internet or when you haven’t been around to turn the computer on for a longer period of time.
Ultimately, Windows Defender might fail to update the definitions itself for whatever reason. In such cases you must either force a definition update by navigating to the designated tab of Windows Defender or by downloading and installing the latest signature definitions.
The Windows Defender Definition Updates are offline packages containing the most recent antivirus signature for Windows Defender. Once installed, they will make sure your PC is safe from the latest known viruses, spyware, PUPs, and malicious files.
It is very important that you download and install the 32-bit release for x86 systems and the 64-bit release for x64 systems. Furthermore, please pay attention to the download links, since they are designed for different Windows iterations. Other than that, deployment is fast, so you will have your Windows Defender updated in minutes.
