Windows Defender Message When Starting Windows Vista

Hits:47

 Q: Each time I start Vista, I receive the following message from Windows Defender:
 
 "An Application Registration change was made for a known application file : C:\Progarm Files\Windows Defender\MpCmdRun.exe."
 
 Is there anything I can do to tell Defender that I don't want to see this anymore. Nothing appears to be wrong with the system...it's running fine.
 
 A: To turn off Windows Defender notifications, follow the instructions below:
 
 Open Windows Defender
 
 Select Tools
 
 Select Options
 
 Scroll down the page and uncheck the option titled: "Choose if Window Defender
 should notify you about: Changes made to your computer by software that is permitted to run"
 
 Click OK
