Can I hide the Security Center icon in Windows Vista?
Yes you can.
The Security Center is an application that informs Windows XP SP2 and Windows Vista users about their security settings, or better saying – the lack of.
Windows Security Center in Windows Vista has a separate section for the Firewall, Automatic Updates, Malware Protection (Anti-Virus and Anti-Spyware protection), and other settings. If one of them is not installed, not configured, or outdated, the Security Center will inform you about this by showing a yellow icon in the notification area of the tray.
Sometimes one might wish to keep their settings that way and might not want the Security Center to nag him or her about it. Hence the requirement to remove the nagging icon. In order to do so perform the following steps:
Right-click the Security Center icon in the notification tray, select Open Security Center.
In the Security Center window, click on the “Change the way Security Center alerts me”
In the “Do you want to be notified of security issues” window click on “Don’t notify me and don’t display the icon (not recommended)”.
Another, more advanced note: If you don’t want to go through all the clicking and crap that the Vista inventors have imposed on us, you can simply execute the following command from the Run command:
"C:'Windows'system32'rundll32.exe" C:'Windows'system32'shell32.dll,Control_RunDLL "C:'Windows'system32'wscui.cpl",Security Center
This also works in Windows XP/2003.
