Windows 11 is experiencing a bug that’s causing it to play the Windows Vista startup sound instead of its own. This issue was first noticed in the Dev Channel build 26200.5651, where the sound file was swapped in the imageres.dll file. Microsoft has acknowledged the mistake and is working on a fix.
What caused the issue?
The exact technical reason behind the mix-up isn’t clear, but it’s believed to be an accidental replacement of the standard Windows 11 startup sound file with the Vista one during internal builds.
Microsoft’s Response
A Windows Insider team member joked about the error on social media, but Microsoft has confirmed it’s a bug and is working to resolve it. The company has added this issue to their list of known problems for the Dev and Beta Channel flights.³
Fixing the Issue
Since Microsoft is already aware of the problem, users can expect a fix to be rolled out soon. In the meantime, you can keep an eye on future updates to see when the issue is resolved.
