I installed the Windows 10 on the 29th of July, 2015 Windows Defender hasn't ran a scan.

I started getting alerts that a scan is necessary to keep Windows 10 protected.

In the settings there's no scan setting like there was on Windows 7

I can manually scan, but I want it to be a full automatic scan every day.

How do I set Windows Defender to run a full auto scan every day?

In Windows 10, you do not need to setup a custom schedule for full scan for Windows Defender because it is already scheduled to run Quick-San daily. Full system scan uses more system resources for along time witch affects your system performance while it is scanning and you don't need it every day. Moreover, Windows Defender includes RTP, which monitors your computer continuously.

It certainly is true that real-time protection mitigates the need for scheduling Full Scans – but the new Windows Defender actually uses a much more powerful “on-access” real-time protection – a kernel-mode mini-filter driver (WdFilter.sys) that continuously scans file-system activity. On the other hand, it’s entirely possible for hidden malware to fly in under this on-access radar, because this form of real-time protection has to be very quick in order to keep it from bogging down the system – and consequently it never takes the time to scan the contents of archived files. So a Full Scan is still very useful because it does unpack those container files in search of any hidden (but inactive) malware that might have gotten through your primary line of defense.

What we need to look at here is the rationale for adding a scheduled scan by modifying the Windows Defender Scheduled Scan task. First, ask yourself this question: If Automatic Maintenance already runs a Quick Scan on a daily basis, then what possible reason would there be for adding a second scheduled Quick Scan? The Microsoft method just adds a totally redundant scan, which doesn’t really make any sense, but otherwise is completely harmless.

It should be clear that the only additional scheduled scan that would make any sense would be a scheduled Full Scan. Unfortunately, if you schedule a Full Scan by changing the command line (action) of the Windows Defender Scheduled Scan task, as the Windows Club tutorial recommends, the result might not be quite what you expected, and it also might not be quite so harmless. The Windows Club tutorial, like many of the other Windows-help site tutorials, was copied from the Eight Forums tutorial (recommended above by PA Bear MS MVP); and the Eight Forumsmethod was based on the mistaken notion that the Windows Defender Scheduled Scan task was NOT being triggered by Automatic Maintenance:

But of course it IS being triggered by Automatic Maintenance; so if you schedule a weekly Full Scan with this method; for example, the unintended consequence is that the daily Automatic Maintenance scan is also converted into a Full Scan (you can easily confirm this in Event Viewer).  Not only does that not make any sense; it also makes it quite likely that you’re going to create some kind of bottleneck in the Automatic Maintenance workflow, since the default mode for this service runs maintenance tasks strictly during system idle states and within strictly limited “maintenance windows”. So if you decide to cut corners here and go with this “simple” method of creating a scheduled Full Scan, you should definitely pay close attention to the results that get logged in Event Viewer and Task Scheduler. Also, the new Windows Defender icon might be useful for monitoring your scans – if you load it at startup:
