Windows 10: Windows 10 Pro Update and Defender dissapeared

Hi!
A few days ago I had a ransomware malware. I had nothing of value on my laptop and I manage to stop it using a ceratin app. But it somehow "deleted" my Windows Defender and Windows Update. I cannot search for Update, It sais that some seting are managed by my organisation. If I try searching for updates, I get the folowing error:
"There were some problems installing updates, but we'll try again later. If you keep seeing this and want to search the web or contact support for information, this may help: (0x80070424)"
Is there something I can do to restore these services without reinstalling Windows?
Thank you!
P.S.: Windows 10 Pro Version 1909 (OS Buid 18363.836)

:)

 

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.

Hi,

Thank you for posting the query on Microsoft Community.

I appreciate your interest on Windows 10.

I suggest you to follow the steps below:

• Type defender in the search box.
• Click on update.
• Check for the date on which defender is being updated.
• If the recent date is mentioned then it will not show in the Automatic Updates.
• Also click on update definition and check if any update is pending.

Please get back to us with updated status. We will be happy to assist you further.

 

Microsoft to make Windows 10 updates mandatory

Well, at the moment at least, you can choose to defer upgrades. Under Settings > Windows Updates > Advanced options you need to check the box labeled "Defer upgrades". What does that do? Good question. The answer I've found might illuminate it to a degree.

I hear this only applies to Pro and Enterprise editions. But I can't verify that.
