Windows 10: Windows Update and Windows defender issues

Hey, a new issue turned up on my laptop

Lenovo ThinkPad T430s

Windows 10 Pro Education.


I have attached the relevant screenshots. Windows Update says 'Your device is missing important security and quality fixes' and won't check for updates.

Another is that the Windows Defender has completely disappeared.


Please guide how to solve them.

Thanks in advance!

Windows 10 Anniversary Update Issues

Problems with W10 Anniv auto update:

Mom's: (x58 Xeon 5677) Windows Defender was not turned back on automatically (it was "on" in the 1511 edition) and she had a Trojan. Full system scan to eradicate.
Her Epson printer was knocked off, had to uninstall by Device Manager pull USB cable and reconnect cable. W10 did the rest.

Step-mom's: (HP pre built) Windows Defender not turned back on by default. Her USB Seagate Expansion Drive 2Tb was offline so all backup routines were halted. Had to rerun backup plan. Had her do a full virus scan.

Step-dad's: (Dell Optiplex tweaked upgrades) Windows Defender not turned back on by default. Full Scan.

 

SEtting up automatic updates for windows defender on windows 8

I have found this on the internet en have set up a task for automatic definitions update for Windows Defender but a window pops up when this starts to run.
Is there a way to set this without any window popping up so that it just runs in the background?

Now I'm using
"C:\Program Files\Windows Defender\MpCmdRun.exe" -SignatureUpdate -MMPC

I'm currrently using it as described here:

What the hell, windows defender?

Installing major updates like the April update will reset pretty much all Windows features including Windows Defender.
