How to get the latest definition updates for Windows Defender

Standard

This article describes how to update your Microsoft Windows Defender in two ways:

A) Force a daily update

If you want Windows to update your software, go to Windows Update or:

a. Open your Microsoft security software.

b. Click the Update tab.

c. Click the Update button.

Usually, updating once a day gives you a good level of protection, and it prevents us from constantly updating your software and interfering with how you use your PC.

 

B) Manually download the latest updates

Sometimes you might want to update more often. This can be helpful if you have hard-to-remove malware, Windows update isn’t working properly, or you aren’t always connected to the Internet.

To download these updates, Check whether your version of Windows is 32-bit or 64-bit.

I) To download the Windows Defender definition update file for 32-bit (x86-based) versions of Windows, follow these steps:
1. Click the following link:  http://go.microsoft.com/fwlink/?linkid=70631

2. In the download dialog box, click either Run or Save.

  • Click Run to install the definition file immediately.
  • Click Save to save the definition file to the computer. To install the saved definition update file, click Start, click Run, locate the folder where you saved the definition file, double-click the Mpas-fe.exe file, and then click OK.
  1. When the definition file runs, a file extraction dialog box appears. The dialog box indicates that the definition update is installing. After the file extraction dialog box closes, to verify that the Windows Defender definitions are updated, follow these steps:
  • Start Windows Defender.
  • Check the definition version that is listed in the box at the bottom of the Windows Defender Home dialog box.

 

II) To download the Windows Defender definition update file for x64-based versions of Windows, click the following link: http://go.microsoft.com/fwlink/?linkid=70632 and follow the above steps.

Hope it helped.

Cheers!
