Thanks. I'm glad you're able to see my point of view. > I would say that none is sent on basic, but the definition of 'private or personal' is overloaded enough that we might disagree. It's less about definitions, and more that I just can't be sure what exactly is sent. > Lots more info here: Thanks, that was informative. It seems they gather as complete a profile as they can of all my hardware and of the software they deem relevant (drivers, Microsoft apps) and its configuration. This is clearly enough for a globally unique fingerprint, many times over. (I don't know that they're building one, but they clearly can.) The part that most worries me here is that at every point this doc says the list is inclusive, not exclusive. "The data gathered at this level includes". "Examples include". "Device attributes such as". There's no wording that I can see that would exclude anything at all that Microsoft might choose to collect now or later. This holds for the Basic level, unlike the Enterprise-only Security level that explicitly says "No user content, such as user files or communications, is gathered" and "we take steps to avoid gathering any information that directly identifies a company or use". It's pretty clear that this doesn't hold for the Basic level. (Even if the purpose of gathering the data isn't to identify anyone.) > nor does that article mention the GDPR. You're right, it predates the GDPR and refers to a Dutch law. I was wrong to reference it and I'm sorry for muddying the discussion. I read the Microsoft Privacy Statement (https://privacy.microsoft.com/en-US/privacystatement https://privacy.microsoft.com/en-US/privacystatement). It says: > Many of our products require some personal data to provide you with a service. If you choose not to provide data necessary to provide you with a product or feature, you cannot use that product or feature And then in the section on Windows: > Rather than residing as a static software program on your device, key components of Windows are cloud-based [...] In order to provide this computing experience, we collect data about you [...] It seems Windows is included in the statement that collecting personal information is mandatory and without it you "cannot use that product or feature". Although it's not explicit and so that may not be the intent for Windows - but it's not clearly disclaimed either. Of course, any claim that collecting "Basic" data is truly required for Windows to work well is highly suspect because the Enterprise edition doesn't do it. But OK, there's a "Learn More" link at the end of the Windows section that shows much more text. Unfortunately, while it includes many details, it also contains lots of inclusive statements. E.g., Activation is said to send "data about the software and your device" with no further explanation. Bottom line: I would like to trust Microsoft (in this particular regard, at least). I think it's more likely than not that nothing terrible is going on. I think so because collecting data about me is not really part of Microsoft's business model, does not benefit them in any obvious way, and might harm them if it became known. But it would help a lot if Microsoft made a clear public statement (and put it in their contracts and EULAs), instead of all this "for example" wording.
