Ive folowd the bellow method. Didnt remove it. Now Im asking if ther will be other negative consequences ?
The following procedure removes the shield overlay only from icons and Start Menu items, which means that the shield overlay will not be removed from Control Panel applets and context menus. Here's how to do it, once and for all:
Make sure UAC (User Account Control) is disabled by moving its slider to the lowest position.
Open the Command Prompt.
Type the following commands, pressing Enter after each line:
taskkill /IM explorer.exe /F
CD /d %userprofile%\AppData\Local
DEL IconCache.db /a
shutdown /r
NOTE: The last command will restart your computer, so make sure you save your work BEFORE executing those 4 lines above!
If you ever experience the shield icon again (I believe that's impossible now), just repeat the third step. Good luck!
