Windows Update does not fresh-install Preview 7 #15692

Prerequisites

• Write a descriptive title.
• Make sure you are able to repro it on the latest released version
• Search the existing issues.
• Refer to the FAQ.
• Refer to the known issues.

Steps to reproduce

Follow steps based on Preview updating PowerShell 7.2 with Microsoft Update:

Ensure PowerShell 7.1.3 is installed but no PowerShell preview releases are installed.

Create registry values [HKEY_LOCAL_MACHINE\Software\Microsoft\PowerShellCore]UseMU:dword=1 and [HKEY_LOCAL_MACHINE\Software\Microsoft\PowerShellCore\InstalledVersions\39243d76-adaf-42b1-94fb-16ecf83237c8]Install:dword=1. Additionally, as directed in a workaround described in #15510, create a registry key HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\PowerShellCore\InstalledVersions\31ab5147-9a97-4452-8443-d9709f0516e1.

Ensure Windows Update is set to Receive updates for other Microsoft products when you update Windows. In my case, this is enforced by my organization through MDM.

Reboot and check Windows Update, installing all available updates and manually rechecking until no updates appear.
