Where did your Win 10 install come from?
Which version of 10 is it?

Its version 1803 and it was already installed from the shop I bought it from.

Home, Pro, Enterprise, Insider?
Because that looks specifically like a message you'd get from Enterprise or Insider.

"...already installed from the shop I bought it from."
Still looks like something not quite valid.

Did they give you the license key?
Can you retrieve it? Belarc Advisor can probably discover this license key.


Bottom line - You don't simply make that message go away. Instead, you discover why it is there, and fix that.

I am also having this problem on my PC. I have home edition, and my PC was originally Windows 8 home edition. As part of the 1803 update it supposedly updated Windows Defender, so it would seem Microsoft goofed. On the plus side it only gives the error when I right click the Windows Defender icon and try to manually check for updates. If I go into the program and go to virus protection and can start an update check from there. https://docs.microsoft.com/en-us/windows/whats-new/whats-new-windows-10-version-1803

Another work around is

This started happening to me right after I installed the big April update. Workaround that worked for me is to go into Task Manager under Background Processes and close the Windows Defender Notification . When the icon disappears from the system tray, go to c:\Program Files\Windows Defender and open MSASCuiL.exe. Then the system tray icon returns with the green check mark.

But when I restart the computer I get the red x again, so I have to go through this all over again each time I restart.

Please fix this, Microsoft!
