Manually updating Windows can be made you a test user

Microsoft uses different types of Windows updates to improve quality and security, explains Michael Fortin, vice president of Windows at Microsoft. The B-releases are known, of which the ‘B’ refers to the second week of the month. These are the updates that mainly consist of security patches and which also appear on the Tuesday known as patch Tuesday, or update Tuesday.

But there are also C and D releases according to Fortin, which therefore appear in the third and fourth week of the month respectively. “These are preview releases, particularly intended for commercial users and advanced users who ‘search’ for updates,” the vice president says, explaining that this search is based on “Check for updates” on Windows Update. “The purpose of these releases is to test the non-security updates that are part of the subsequent Tuesday updates,” he continues.

Microsoft has the Insider program for testing Windows, which users must explicitly sign up for. However, this is primarily intended for testing upcoming Windows versions with corresponding new features. Few average users will at least know that they are likely to become test users by manually checking for updates. In addition, Microsoft also does not report this with Windows Update. The extent to which the C and D updates have not already been tested by Insiders, for example, is not known.

Precisely for this reason I run the following PowerShell script on my WSUS server to periodically exclude these preview updates. You can put this for example in a scheduled task.

This is a useful PowerShell script, because there is no classification for the preview updates within WSUS and therefore you can not disable the preview updates from the GUI.
