Here is what is in the Defender Operational Log: I reset Defender scans to occur every Friday at 9PM. Is there a rationale for changing the “one-stop shop” MSE Windows 7 user interface into the Windows 10 Defender multiple interfaces? (Other than the fact that someone thought that a new operating system needed changed interfaces.) And a Google search to locate scan results showed me three or four different ways to get the results, and I am not sure that each method will give me the same results. I re-scheduled my weekly scan, but I cannot find in that window where to tell Defender what directories and files NOT to scan. I set that switch to ON, but it appears that when 2004 was “auto-installed” a week ago, it changed my settings back to “factory” – disabled Periodic scans, and lost my Friday full-scan setting. It seems to me that if I set an MSE full scan, then the “Periodic scans” switch should be changed automatically to ON. Somewhere in Settings I found a switch that had “Periodic scans” set to OFF. I told Defender to run a scan every Friday at 7PM, but I had no idea if it ever ran. I have been using Windows 10 in production for about three weeks.

In Windows 10, it appears that Defender is either one multi-headed application or a number of separate applications. Everything with MSE was controlled from this window. I could open the MSE window and see what was happening. (It sometimes did not honor my request.) When a scan was running, the MSE icon was sitting in the system tray, with a spinning circle. I have a number of hard drives in my machine, and I told MSE what disks and directories not to scan.

In Windows 7, I had set up Microsoft Security Essentials (MSE) to run a full scan at 7PM each Friday.
