Found this little tweak for getting rid of that annoying little secuity sheild logo in the tray....
1. If you're familiar with the Windows Command Prompt, open it (choose Start > Run > type: cmd > press Enter) type these two lines in succession:
sc stop wscsvc
sc config wscsvc start= demand
(Note: The space after the equals sign is required.)
To reverse these steps, use these two commands entered the same way:
sc start wscsvc
sc config wscsvc start= auto
2. The second method uses a graphical process. Choose Start > Run > type: services.msc > press Enter. That opens the Services box. On the right side, click any name in the Name column. Type S to scroll the list quickly. Look for the "Security Center" entry and double-click it to open its properties page.
Toward the bottom in the "Service status" area, click the Stop button. Just above that, open the "Startup type" dropdown menu and choose "Manual." Click OK and close the Services window.
To reverse the steps, click the Start button and choose Automatic from the dropdown menu.
Whew, it's finally gone.
