Windows 10: Windows 10 context menu option to "Scan with Windows Defender"

All

Can someone tell me if the option above has vanished as a result of the Windows Update of 10 10 2017?

I no longer see this option.

How can I re-enable it?

Thanks

Windows defender in Windows 10 64 bit

It was actually "taken away" in Windows 8/8.1; but “Scan with Windows Defender” was added to the Windows 10 context menu in November:

Windows 10 November Update: Right Click Scan with Windows Defender



In Windows 8/8.1 you can add a Windows Defender command line scan to the context menu with either a downloaded reg file, or a DIY batch file:

No one seems to know why the context-menu scan was dropped – but you can still get the equivalent functionality with the command line interface, although it’s little on the homely side. You can either download and run a reg file to get a context-menu
scan; or you can use your own 2-line batch file for drag-and-drop and context-menu scanning. Both methods are covered in this thread:

Which version of 10? Anniversary Update (1607) or Creators Update (1703)? Both got cumulative updates on Tuesday 10th.

My 1703 has had the update (now on build 15063.674) and I still have the 'Scan with Windows Defender...' context menu.

Maybe it's something more than just a missing menu, can you start a manual custom scan from Defender itself? If not, malware may be stopping you. If there's nothing untoward going on, then this tutorial should help.

Scan with Windows Defender Context Menu - Add in Windows 10

 

I am using Windows 10 Creators Edition, Version 1703 with Build 15063.674.

But I can only run manual scans within Windows Defender itself, but from a context menu.

I have since applied a fix at Add Scan with Windows Defender to Windows 10s Right-Click menu and this does open a command prompt which runs a scan. However, it is limited.

But where has the original option gone?

 

It should not have gone - I still have it. Are you sure it's not malware that has removed it? Try a scan with AdwCleaner.

If it turns out that you are clean, you could try sfc/scannow and DISM's /RestoreHealth option...

...,and if those don't fix it, there's...

I should have remembered. This is to do with settings in Malwarebytes for Windows Action Centre. This issue is resolved.
