musicon writes "According to Nadim Kobeissi, Windows 8 is configured by default (using a new featured called Windows SmartScreen) to immediately tell Microsoft about every app you download and install. This is a very serious privacy problem, specifically because Microsoft is the central point of authority and data collection/retention here and therefore becomes vulnerable to being served judicial subpoenas or National Security Letters intended to monitor targeted users. This situation is exacerbated when Windows 8 is deployed in countries experiencing political turmoil or repressive political situations.
Additionally, it may be possible for a 3rd party to intercept SmartScreen’s communications to Microsoft and thus learn about every single application downloaded and installed by a target."
