Windows 10: MSASCuil

Hi my pc been acting funny for a while and idk what happened. Basically i logged in then found a black screen so i oppened task manager and it crashed. After a few days i tried again and it worked. I opened task manager and went to start up and found MSASCuil, it didn't have published by Microsoft Coorporation so i disabled it and now im running a full scan.

Hi HARILAXMI

where are you seeing MSASCuil?

which version of windows 10 are you running?

settings -> system -> about

what is listed under windows specifications?

msascuil (Microsoft Antivirus Security Centre User Interface Logo) was responsible for the icon appearing on the taskbar system tray, but apparently was later incorporated into the windows security health service and SecurityHealthSystray.exe.

Missing Startup Software

1803 was the last version to include MSASCuiL.exe and MSASCui.exe, they were removed in 1809 and all later versions.

The purpose of MSASCuiL was to display the old Defender icon in the taskbar, while MSASCui was the old Defender UI.

Neither are needed (or will work) in 1809 or higher. In fact, attempting to run the old MSASCui.exe from 1803 in any recent version of W10 will now just open the Windows Defender Security Center.

A leftover for a previous version after updating it? It is not needed as your Startup list also has the item that's now used in place of MSASCuiL, the 'Windows Security notification icon'.

It is safe to delete the MSASCuiL startup entry from the registry (if that's where it is). It may not be a registry entry, it may be a shortcut in your %appdata%\Microsoft\Windows\Start Menu\Programs\Startup folder. Early versions of W10 did not show the taskbar Defender icon by default, it was common practice for users to put a shortcut there to make it show on the taskbar.
