Sending Feedback

I think MS has that little proviso in all their beta and pre-beta programmes.

I have always sent feedback regardless of the origin of my build.

What information will be sent to Microsoft?
If you choose to help us improve Windows installation by participating in the Windows Installation Customer Experience Improvement Program, Microsoft will collect information about your hardware configuration, how you install Windows, and specific errors you encounter during installation. Microsoft collects this information whether your installation is successful or not. Microsoft uses this information to identify trends and usage patterns, help determine which updates are needed, and identify areas for improvement.

Windows installation also provides an error reporting service that monitors your computer for problems that will prevent a successful installation. This service automatically sends a report to Microsoft if an error occurs. Error report data is used to find and fix problems in the software you use. It is not used for marketing purposes.

What data is collected?
To fix problems in the software you use, we collect information about what the software was doing when it experienced the problem, and about your machine configuration. Microsoft does not collect your name, address, or any other contact information.

How is data stored?
When you submit an error report, we help protect it through the use of encryption, such as the Secure Socket Layer (SSL) protocol. When we receive an error report, we use a variety of security technologies and procedures to help protect your information from unauthorized access, use, or disclosure. For example, we store the error reports you provide on computer servers with limited access.

Who has access to error report data?
Microsoft employees, contractors, and vendors who have a business need to use the error report data are given access to this information.
By sending this information to Microsoft, you are helping to improve the quality, reliability, and performance of Windows installation.

Collection of information about your computer
Windows 7 contains several Internet-enabled features that collect standard information from your computer ("standard computer information"). Standard computer information typically includes information such as your Internet Protocol (IP) address, operating system version, browser version, and regional and language settings. In some cases, standard computer information might also include hardware ID, which indicates the device manufacturer, device name, and version. Some features might collect additional information. The privacy details for each Windows feature listed in this privacy statement will disclose the additional information that is collected and, if the feature sends the information to Microsoft, how it is used.
Use of information
Information that is collected by or sent to Microsoft might be stored and processed in the United States or any other country in which Microsoft or its affiliates, subsidiaries, or service providers maintain facilities. Microsoft abides by the safe harbor framework as set forth by the U.S. Department of Commerce regarding the collection, use, and retention of data from the European Union.
Microsoft may access or disclose information about you in order to: (a) comply with the law or respond to lawful requests or legal process; (b) protect the rights or property of Microsoft or our customers, including the enforcement of our agreements or policies governing your use of the services; or (c) act on a good faith belief that such access or disclosure is necessary to protect the personal safety of Microsoft employees, customers, or the public.
Microsoft occasionally hires other companies to provide limited services on its behalf, such as providing customer support, processing transactions, or performing statistical analysis of reports. Microsoft will provide these companies only the information they need to deliver the service. They are required to maintain the confidentiality of the information and are prohibited from using it for any other purpose.
Security practices
Microsoft is committed to protecting the security of your information. We use a variety of security technologies and procedures to help protect your information from unauthorized access, use, or disclosure. For example, we store the information that you provide on computer servers that have limited access and that are located in controlled facilities.
