You are alerted so that you can take action when Windows Defender detects software or changes made by software that has not yet been analyzed for risks. In addition to basic information, Windows Defender sends more information to Microsoft about spyware and potentially unwanted software, including the location of the software, file names, how the software operates, and how it has impacted your computer. In some instances, personal information might unintentionally be sent to Microsoft; however, Microsoft will not use this information to identify you or contact you.
