doc: Deprecated (deactivated) Windows Dev Home in BUILDING #61424

Situation

The BUILDING > Windows > Option 2: Automated install with WinGet includes the advice:

Alternatively, you can use Dev Home
to install the prerequisites:

• Switch to Machine Configuration tab
• Click on Configuration File
• Choose the corresponding WinGet configuration file
• Click on Set up as admin

The Microsoft documentation link Dev Home states:

Starting May 2025, Dev Home will no longer be supported as a feature in Windows 11.

Attempting to install Dev Home from https://aka.ms/devhome, leads instead to the Windows Advanced Settings app - https://github.com/microsoft/windowsAdvancedSettings

https://github.com/microsoft/devhome was archived in June 2025.

The last Dev Home release from https://github.com/microsoft/devhome/releases/tag/v0.2001.758.0 was published one year ago in Jan 2025.

• It carries a label "Dev Home Preview v0.20"
• Installing and running it shows a message

  Dev Home will be going away in May 2025 and a subset of its features will be moved to new places. Stay tuned for more information in the following months.

• Subsequently running Microsoft Store Downloads, "Check for updates" removes "Dev Home (Preview)" from the start menu

Conclusion

Microsoft Windows Dev Home has not only been deprecated, it has been deactivated. The corresponding instructions in the BUILDING.md document can no longer be followed.

There is no "Machine Configuration tab" in the follow-on app https://github.com/microsoft/windowsAdvancedSettings, so it is no longer possible to follow the instructions based on using "Dev Home".

Suggestion

Remove references to Dev Home from the BUILDING.md document.
