Hello，Francis Erwin Roxas
Welcome to posting in the Microsoft Community.
I can understand the trouble you are experiencing while trying to transfer files from your old laptop to your new Windows 11 PC, it is really frustrating. Usually, it's quite common for the username and password prompts to appear when there is a need to connect and share files between devices, especially if the file transfer is done via network sharing.
So I'd like to ask what method are you transferring files through?
If you are transferring files via a network share, then you need to set up the shared folder and make sure both devices are on the same network. Make sure the folder on your old laptop is shared and you have access to it. In this case, the username and password entered are usually the login credentials for your old laptop. If this information still does not resolve the issue, there may be an error in the sharing settings or security settings and you will need to consult the Microsoft Learn community further for more assistance.
We recommend that you move to the Microsoft Learn community, which is Microsoft's platform for addressing these types of technical issues. There you can find more detailed answers to shared questions and similar cases, and even direct help from other users or Microsoft support staff, which is one of the best ways to quickly resolve a problem.
The current forums initially had Windows Client sections for IT pros, but it has recently migrated to Microsoft Learn, so you'll need to take the time to post questions in Microsoft Learn.
Here is the link to the Windows 11 - Microsoft Q&A forum where you can copy the question and post it directly to the appropriate forum and section (I have selected the appropriate forum and section for you).
The reason why we recommend you to go to Microsoft Learn is because drive sharing involves more technical points and the platform can provide more detailed instructions and support from professionals. I realize that you may want to get right to the point here, but due to the complexity of the issue, we want to provide you with a more appropriate resource.
I sincerely hope that after contacting the relevant authorities, your issue will be resolved as soon as possible.
Thank you for your understanding, I really appreciate it!
I wish you all the best!
Best Regards，
