WSUS: IUpdateInstaller2::ForceQuiet Property

i using wsus 3.0 install many updates silent possible automatic deployment.
if iupdateinstaller2::forcequiet property set "true" can install collection of updates (iupdatecollection) in silent mode. somes updates cannot installed in silent mode (without user interaction)! once updatecollection contains update cannot installed in silent mode error returned , update not installed.
how can find out wether update can installed silent or not? did not find property indicates wether update can installed silent or not. suggestions? if there possibility set updatecollection contains updates can installed silent.

thanks in advance!

there metadata value identifies whether user interaction may required. in wsus ui it's identified "may request user input". you'll have check sdk actual property name in api. testing value no should definitively identify updates can install in quiet mode.

updates value "yes" *may* require user input.. doesn't mean will, it's conceivable won't, , of them, also, can installed in quiet mode.

the best way make determination use test client, , see if update install in unattended environment.
