Microsoft Security Essentials command line flags

Microsoft always seems to leave the good stuff undocumented.

There's a few documentation about command line flags for MSE's command line process MpCmdRun.exe, but none for the GUI's process msseces.exe.

I decided to take a look at process msseces.exe from Process Explorer and found a few interesting flags, such as:

UpdateAndQuickScan
QuickScan
FullScan
Settings
Update

There are a few more, including one by name of Callisto. WTH is that? Unless it's not a command flag, at all. I didn't even try to see what it does.

Anyway, if one were to create, say a Desktop context menu for MSE, one could add a command such as C:\Program Files\Microsoft Security Client\msseces.exe -QuickScan. This would open MSE GUI and start an automatic scanning.

There's also a flag NoRemove, which I suppose that if used, would make MSE not delete threats? Does MSE automatically delete threats found by on-demand scans? I don't recall.

Anyway, just thought some of you could find it useful.
