Your browser history syncs by default
According to the privacy agreement, when you sign in to Windows 10 with a Microsoft account the operating system will automatically sync “some of your settings and data with Microsoft servers”. This includes “web browser history, favorites, and websites you have open” in addition to “saved app, website, mobile hotspot, and Wi-Fi network names and passwords”.
If you're a Windows 10 user, there is a way to deactivate this by going into settings and finding “Sync your settings” in the Accounts tab. However, the fact that this isn't an opt-in feature means many users won't think to change it.
Advertisers can track your activity
Another iffy point in the terms and conditions relates to capitalising on personal data. Windows 10 creates a unique advertising ID for each user. This ID can be used by app developers and advertising networks, and basically means that third parties are able to use your data to send you targeted ads.
“The ads we select may be based on your current location, search query, or the content you are viewing. Other ads are targeted based on your likely interests or other information that we learn about you over time using demographic data, search queries, interests and favorites, usage data, and location data.”
Like automatic data syncing, this can be turned off in settings. To do this, go to Settings | Privacy, and flick the first switch on the list of options.
Your encryption key is automatically sent to your OneDrive account
This last one isn't bad in itself, but it will present a problem if OneDrive suffers a data breach in the future. With device encryption turned on, Windows will automatically encrypt your drive and generate a BitLocker recovery key. This key is backed up, again automatically, onto your Microsoft OneDrive account.
Taken altogether, the main Windows 10 privacy concerns relate to opting in to features without asking your permission. There's also some vague gesturing from Microsoft towards what data will be used and when. While Windows 10 is a strong operating system, it does present a shift towards tech companies taking greater control over your personal data, and that is something users need to fight against.
