This is becoming tragicomic, no less. First it was an optional upgrade, then it became a forced optional upgrade and now it has become a recommended upgrade?
To start off, I am always first and do use Windows 10 or more correctly, I have battled Windows 10 since its release and only the last 6-8 weeks it has been quiet enough to protect my privacy so much as it is said.
Many updates do deliberately reset privacy settings to allow Microsoft to spy on you and so unless you have more defenses against it, you have to be on the alert and check your settings frequently, let that be the basis for the below.
I am concerned on behalf of Jane and John Doe as Microsoft does not accept any responsibility if the upgrade goes wrong even if it has been brought to their knowledge that it will fail. Trouble is, it will fail for many of you who are running on older hardware and so I have to urge you to go to the hardware manufacturers website and check compatibility for your computer as soon as possible.
Based on the fact proven without doubt, the enormous privacy breach the entire spyware operating system Windows 10 really is. I also must advise all of you who are handling sensitive data to go back to Windows 7. It is in your interest to keep your data private, and I can already guarantee you that Microsoft has access to all medical journals and any other sensitive data you are handling if you are on Windows 10.
Be aware that they do record much: (The following are from their privacy statement)
Name and contact data. We collect your first and last name, email address, postal address, phone number, and other similar contact data.
Credentials. We collect passwords, password hints, and similar security information used for authentication and account access.
Demographic data. We collect data about you such as your age, gender, country and preferred language.
Interests and favorites. We collect data about your interests and favorites, such as the teams you follow in a sports app, the stocks you track in a finance app, or the favorite cities you add to a weather app. In addition to those you explicitly provide, your interests and favorites may also be inferred or derived from other data we collect.
Payment data. We collect data necessary to process your payment if you make purchases, such as your payment instrument number (such as a credit card number), and the security code associated with your payment instrument.
Usage data. We collect data about how you interact with our services. This includes data, such as the features you use, the items you purchase, the web pages you visit, and the search terms you enter. This also includes data about your device and the network you use to connect to our services, including IP address, device identifiers (such as the IMEI number for phones), regional and language settings. It includes information about the operating systems and other software installed on your device, including product keys. And it includes data about the performance of the services and any problems you experience with them.
Contacts and relationships. We collect data about your contacts and relationships if you use a Microsoft service to manage contacts, or to communicate or interact with other people or organizations.
Location data. We collect data about your location, which can be either precise or imprecise. Precise location data can be Global Position System (GPS) data, as well as data identifying nearby cell towers and Wi-Fi hotspots, we collect when you enable location-based services or features. Imprecise location data includes, for example, a location derived from your IP address or data that indicates where you are located with less precision, such as at a city or postal code level.
Content. We collect content of your files and communications when necessary to provide you with the services you use. For example, if you receive an email using Outlook.com, we need to collect the content of that email in order to deliver it to your inbox, display it to you, enable you to reply to it, and store it for you until you choose to delete it. Examples of this data include: the content of your documents, photos, music or video you upload to a Microsoft service such as OneDrive, as well as the content of your communications sent or received using Microsoft services such Outlook.com or Skype, including the:
- subject line and body of an email,
- text or other content of an instant message,
- audio and video recording of a video message, and
- audio recording and transcript of a voice message you receive or a text message you dictate.
That was just from their privacy statement.
The EULA includes collection of keystrokes on a general level and more and so yes. Windows 10 in its current state can not be considered anything but a large security breach in itself.
Actually a little funny, but even Windows XP must be considered a more secure OS at current as you at least have to be hacked before anyone can get to your data. In windows 10, you are already pre-hacked by Microsoft.
