Hi, TunerPsyko48
Welcome to Microsoft Community.
We understand that you want to customize the Windows 11 startup sound, but you want to do it in a way that does not modify the system.
It is important to explain that currently in Windows 11, if you want to customize the startup sound, then modifying the Windows Login value in the registry is an indispensable step, and there is no alternative way to get rid of it, it involves modifying the registry, but only modifying the value that already exists in the registry, not actually modifying the system.
Just in case, I will provide specific steps that can be referenced:
1. Press Windows+R and type regedit
2. Navigate to the following key:
HKEY_CURRENT_USER/AppEvents/EventLabels/WindowsLogon
3. Double-click ExcludeFromCPL DWORD.
4. Set the value data to 0 and click OK to save the changes.
Subsequently, just change the file for the startup sound in Personalization - Sounds.
Disclaimer: Generally, modifying registry subkeys or work group is intended for advanced users, administrators, and IT Professionals. It can help fix some problems, however, serious problems might occur if you modify the registry incorrectly. Therefore, make sure that you follow these steps carefully. For further protection, back up the registry before you modify it. Then, you can restore the registry if a problem occurs. For more information about how to back up and restore the registry, click How to back up and restore the registry in Windows - Microsoft Support to view the article.
Since I am only a community support person and not a developer within Microsoft, everything I offer depends on the features and functionality of Windows, if you want other alternatives, or if the above registry modifications do not meet your needs, we recommend that you can press Windows+F to give official feedback to Microsoft on this issue, only if you give your feedback, the development team will be aware of the problem. Only if you give us your feedback, the development team will be aware of the problem.
