Microsoft regards modifying HOSTS to block Win10 telemetry data as a serious security risk

As an essential part of improving Windows 10 ‘s growth, Microsoft hopes Internet users will enable them to upload part of the telemetry system data. In normal conditions, it will contain essential hardware configuration details such as Processor and memory, which will be totally encrypted during transmission. Based on the review, Microsoft was able to assess the system’s stability and reliability issues and thereby laid the groundwork for future fixes.

Although Microsoft does not encourage users to fully disable the processing of telemetry, the related data obtained by Windows will still be cleaned up.

Paradoxically, while telemetry is seen as important for the development of Windows 10 and other businesses are using the same approach to better their applications, some critics also see it as Microsoft’s “spy.”

Microsoft recently made an update to the Windows Defender security program (aka Microsoft Defender) built into Windows 10.

The app will give a subsequent alert when it senses that the user is trying to prevent telemetry by modifying the HOSTS file.

According to Wikipedia, HOSTS files are used to help with resolution of the network name (i.e. assigning host names to IP addresses).

But Microsoft Defender can explicitly search after the latest Windows 10 update if the user’s HOSTS file has disabled Microsoft’s telemetry function.

If you attempt to change the HOSTS file to avoid telemetry, Windows Protector can cause this alert to discourage the user from taking that move.

You will find that the Protection Center will fail to save the related editing operations on the HOSTS register, which will be labelled as “SettingsModifier: Win32 / HostsFileHijack.”

This file editing activity containing “serious security threats” won’t proceed until you press Allow Access. This upgrade of course also aims to avoid other types of malicious machine file abuse.
