Clients have ie 6 and I pushed out IE 8 through WSUS and they  are geting  IE 8 installed after getting yellow shield without user interactions  and a message appers to restart machien after 15 minurte which isn't the way other updates get installed
( they get installed yellow shield appears on desktop and then user can select updates to install and then click install) but IE 8 doesn't work like don't know why.
There is a seperate gpo setup for IE 8 which is setup as same as for other updates and clients are getting IE8 policy
