Prior to Windows 10 1809, I used the command C:\Program Files\Windows Defender\MSASCui.exe to open the Windows Defender GUI. In 1809, that file doesn't exist. Does anyone know a command to open the GUI of Windows Security in 1809?
Yes, you can use the URI to start it. In a command prompt use the command
start windowsdefender:
In a shortcut, just use windowsdefender:
That, and other URIs can be found in this tutorial.

That, of coures, worked. Thanks and also for the link to the more general information on URIs.
Hi there! I also used "%ProgramFiles%\Windows Defender\MSASCui.exe" to launch Windows Defender, however i also used the "-UpdateAndQuickScan" parameter to launch Windows Defender GUI and do an update and Quick Scan.
I need to replace the MSASCui.exe and the -UpdateAndQuickScan parameter, can someone help?
I know i can use MpCmdRun.exe, but i want to be able to open the GUI instead of running on the Command Line...
Thanks!!
WD now adds & uses new versions of MpCmdRun.exe in new subfolders within C:\ProgramData\Microsoft\Windows Defender\Platform
[it also keeps copies in a few other locations but this is the location it uses as you can see by checking the properties of the antimalware service executable in Task manager]
- To run a scan, I use a batch file to identify the latest subfolder and then run a -scan command within that folder.
- I use a similar method to update malware definitions
These are useful switchesCode:set GetLatestVersionPath="dir "C:\ProgramData\Microsoft\Windows Defender\Platform" /ad /od /b" FOR /F "tokens=*" %%i IN (' %GetLatestVersionPath% ') Do Set LatestVersionPath=%%i "C:\ProgramData\Microsoft\Windows Defender\Platform\%LatestVersionPath%\MpCmdRun.exe" -Scan -1
-Scan -1 runs Quick scan
-Scan -2 runs Full scan
-SignatureUpdate updates the malware definitions
You can get info on MpCmdRun command line switches in its own help info -
First, go to the folder identified above then
either
[in a command window]
enter the command MpCmdRun.exe /?
or
[in a PowerShell window]
enter the command .\MpCmdRun.exe /?
You can search the forum for more info - see, in particular, Schedule Scan in Windows Defender Antivirus - TenForumsTutorials
There is also info at Use the command line to manage Windows Defender Antivirus - Microsoft Docs

Hi there and thanks to both, however i was trying to find a way to, as previous Windows 10 versions, send parameters to Defender GUI, instead of running it on CMD...
If someone knows a way to send parameters to the URI of any other way to launch the GUI and run a quick scan, i would appreciate!
Thanks

If MSASCui.exe is missing, you can try pointing to SecurityHealthSystray.exe inside the system32 folder.
