Control panel - security and maintenance - left pane - change security settings - turn off messages for ? ?= what you don't want to see.
sorry no idea what is steam? the game? i just totally disable it... use on your own risk waste a lot time on disable it anyway... u can enable back with gpedit.msc
Try control panel - admin tools - services - security center - properties- if set to delayed start then stop it and set to manual, see if this helps but doesn't stop the other pop ups you want. If it's not set to delayed, you can try this or set to manual/ disabled for no notifications.
From looking at that reg file I doubt it only gets rid of that one popup and the one from odiebugs doesn't do anything
Tried it and like i thought all it does is disable all notifications and when you do that (which i've tried before) the dumb security center still pops up
security center has always been disabled, but i tried that command in admin mode just for the fun of it but it still pops up. besides if it wasnt disabled i wouldnt get the message to turn it on
i must be missing send the code... i success disable it... maybe this one help too many reg insde my tweak... sorry
that disables all notifications, but even if i disable all notifications security center still pops up
