Windows Defender is the antivirus that comes pre-installed on Windows 10. It's a reliable tool that performs well at all times. As such, it enjoys the trust of most users of the operating system, which is undoubtedly important in these cases. Being an antivirus, it receives frequent updates, including updates to its database, to keep the threat list current.
As we showed a few weeks ago, Windows Defender offers several types of updates , which can be confusing for many users. One type is security intelligence updates, which many don't quite understand. We'll explain it below.
This stems from Microsoft's new plans for this antivirus . The company wants Windows Defender to become Microsoft Defender, as it's a comprehensive security suite for the entire ecosystem. Therefore, the name change means that some aspects will also change, including their names.

Therefore, it is expected that the name of this service will gradually change. It will become Microsoft Defender, which means that the name of its updates will also be modified . This is precisely the issue that interests us, since from now on the term Security Intelligence Update for Windows Defender Antivirus will be used.
Until now, this was known as the Definition Update for Windows Defender Antivirus, which is surely the name familiar to most Windows 10 users. So it's a concept we understand; it's clear and the update makes it easy to understand. The new term reflects the evolution of the antivirus.
There are no firm dates yet for the introduction of the new Microsoft Defender name. It shouldn't be too long, though, if Microsoft is as vocal as it claims to be about its plans. We'll surely have more news soon.
