Asmin password needed for EVERYTHING!

hello you guys. about a month ago i decided to set a setting that would require people to type in my admin password in order to install software, or updates. i really do not need that and i am quite annoyed with having to put the password for basically everything. how to i disable this? i tried looking on Security, account, and even under the software update...but no luck.

help. thanks

 

i've tried that. the checked settings i have now are: Disable automatic login, use secure virtual memory and require password after sleep... i like these settings, i just wan't to get rid of the setting that requires for me to put in my password in order to install updates and software!
