Microsoft's collection of various information through Windows has long been a secret to the public, and Windows Vista has become a peak in this regard. There are dozens of functions and services that send data to Microsoft's headquarters in various ways. Although Microsoft has repeatedly guaranteed respect for privacy and stressed that "you will not use this to identify or contact you", all kinds of worries have never been resolved. Besides Microsoft and God, who knows what happened to Raymond when information about our "IP address, operating system type, name, version, language and code of software such as browsers" arrives? Of course, most people have no choice, because Microsoft's privacy statements and authorization protocols give Microsoft such a right: "using these features means you agree to send the message to Microsoft )." According to statistics, there are 47 features and services in Vista that will collect data, some of which are only stored on local computers for future use, but most of them will contact Microsoft and return data, specifically, it includes: windows Update Dynamic Update Auto Root Update Windows Defender Windows Media Player Internet Explorer 7.0 WGA genuine verification Windows activation Windows Help Windows Time Service Windows Error Report Windows Media Center Windows Mail Service Windows Media Digital Copyright Management (DRM) malware removal tool network connection status icon IPv6 address conversion (Teredo) customer Experience Improvement Program installer Improvement Program Device Manager Event Viewer driver protect game folders Handwriting Recognition Error Report Input Method file association network service Internet print Network found parent control peer network name Resolution Service plug-and-play Extended Program compatibility Assistant Program properties-compatibility tag program compatibility wizard ............ Depending on the function or service type, users may not receive data collection or sharing notifications. The only way to avoid trouble is to understand these services and turn off the report function, even stop the entire service, such as replacing IE 7.0 with Firefox, but many functions or services are very important. In balance, you can only choose to enable them, such as Windows Update.
