Hey everyone,
I've been helping several community members deploy Microsoft Defender for Endpoint in their environments, and there's one consistent piece of feedback that comes up early on: the initial full scan can feel painfully slow. We're talking about scans that seem to take hours longer than expected, especially on machines with large amounts of data or complex directory structures.
From what I've gathered, this isn't necessarily a bug or a sign of a problem. The first deep scan is comprehensive by design—it's building a full baseline, analyzing file relationships, and checking against cloud intelligence. That said, the perceived slowness can cause concern and even lead users to interrupt the process, which we want to avoid.
I'm curious about your direct experiences. Have you found specific settings or configurations that help optimize this first scan without compromising security? For instance, does adjusting the scan priority via policy once the baseline is established make a difference for subsequent scans? Or are there known issues with certain file types or exclusions that you've learned to manage?
Let's pool our practical knowledge. Understanding the "why" behind the initial delay and sharing any legitimate tuning tips would be really valuable for folks rolling this out to their teams.
Keep it civil, keep it real.
