Microsoft famously accused Google of "Scroogling" users by selling their private data to advertisers. But when it launched Windows 10, Microsoft was itself roundly criticized for over-zealous personal data collection. Critics say it does things like send parents reports of their kids' PC use, prevent users from opting out of certain types of data collection, and scan PCs for counterfeit software. The software giant has responded to those accusations in a Windows blog post, saying that it only collects data that makes its products work better and that it gives users control over information collected.
