Windows Defender Full Scan renders devices unusable for 6-7 hours (while scan is running)
We are using Microsoft Defender for Endpoint and configured daily quick scans and weekly full scans. The quick scans don't create any problems but the full scans are a big problem. Devices are not us...
You probably do not need to schedule a recurring full scan. That should be reserved for when you have reason to investigate a specific device. With MDE and EDR, you are unlikely to get much value from it. If you do need to do it, I usually set ScanAvgCPULoadFactor to nearer 25% (not an exact science), but it's going to take hours for little return if real time threat protection is active anyway.
