[1][2][3] Examples include media storefronts, Office 365, paid functionality in bundled games such as Microsoft Solitaire Collection,[4][1][5][6] default settings that display promotions of "suggested" apps in Start menu and "tips" on the lock screen that may contain advertising,[2][3] ads displayed in File Explorer for Office 365 subscriptions on Redstone 2 builds,[3] and notifications promoting the Microsoft Edge web browser when a different browser is set as default.
"[12] Concerns were raised that due to these changes, users would be unable to skip the automatic installation of updates that are faulty or cause issues with certain system configurations—although build upgrades will also be subject to public beta testing via the Windows Insider Program.
Microsoft officially confirmed the change, claiming it was "an industry practice that reduces time for installation and ensures device readiness."
"[40] On January 21, 2016, Microsoft was sued in small claims court by a user whose computer, shortly after the release of the OS, had attempted to upgrade to Windows 10 without her consent.
Critics interpreted this statement as implying that Microsoft would scan for and delete unlicensed software installed on devices running Windows 10.
[52] However, others pointed out that this agreement was specifically for Microsoft online services such as Microsoft account, Office 365, Skype, as well as Xbox Live, and that the offending passage most likely referred to digital rights management on Xbox consoles and first-party games, and not plans to police pirated video games installed on Windows 10 PCs.
[52][53] Despite this, some torrent trackers announced plans to block Windows 10 users, also arguing that the operating system could send information to anti-piracy groups that are affiliated with Microsoft.
"[50] Columnist Kim Komando argued that "Microsoft might in the future run scans and disable software or hardware it sees as a security threat," consistent with the Windows 10 update policy.
The updates' addition of a "Diagnostics Tracking Service" is connected specifically to Microsoft's existing Customer Experience Improvement Program (which is an opt-in program that sends additional diagnostic information to Microsoft for addressing issues), and the Application Experience service, which is typically intended for third-party software compatibility requests.
[56] This was achieved by including various DLLs and adding the telemetry service executable (all of which notably have versions pertaining to Windows 10 builds) as part of various updates from 2016 onward.
[59] The terms of services agreement from Microsoft was updated to state the following:[58] We will access, disclose and preserve personal data, including your content (such as the content of your emails, other private communications or files in private folders), when we have a good faith belief that doing so is necessary to protect our customers or enforce the terms governing the use of the services.In October 2017, the Dutch Data Protection Authority issued a complaint asserting that Windows 10's privacy policies did not comply with the laws of the Netherlands, as it claims that Microsoft does not provide sufficient information on what information is collected at the "Full" telemetry level and how it is processed.
Microsoft disputed the claim that it did not provide enough disclosure of the "Full" telemetry level, and stated that it was working with the DDPA to "find appropriate solutions".
[60] In November 2016, Kaspersky Lab filed an antitrust complaint in Russia regarding the bundling of Windows Defender with the operating system, arguing that Microsoft was abusing its position to favor its own, in-house antivirus software over those of other vendors.
Microsoft stated that the company "[engages] deeply with antimalware vendors and have taken a number of steps to address their feedback", and that they had offered to meet Kaspersky executives to discuss any specific concerns.
