It looks like Microsoft made a bit of a mistake. People testing the latest Windows 11 update noticed something weird – the startup sound was different. It wasn’t the usual sound, but something older. Something from Windows Vista.
This all started on Friday, June 13, when testers began noticing the change in the Dev Channel version of Windows 11. It turned out that the .WAV file that plays the startup sound had been replaced with the one from Windows Vista. This was in version 26200.5651, which was stored in the imageres.dll file.

Microsoft quickly acknowledged the issue and got to work fixing it. They even added a note to the Release Note for the Dev Channel, joking that the update came with a “blast from the past.” But they also made it clear that they were working to fix the problem.
It’s an actual bug.

It’s not entirely clear how this mistake happened, but Brandon LeBlanc, a member of the Windows Insider team, made a joke about it. He said he might have played around with the sound files and thought people might enjoy a trip down memory lane. But he also confirmed that it was indeed a bug.
What’s going on with Windows 11?
The latest update has been making waves, and not just because of the startup sound mishap. Microsoft has been working to improve the operating system, and this update is just one part of that process.
It’s worth noting that this issue only affected the Dev Channel version of Windows 11, which is meant for testing. But it’s still interesting to see how Microsoft handles these kinds of mistakes. They’ve been pretty open about the issue and are working to fix it quickly.
