Solved Username for the system?

From where did Windows use the username for the system? I'm talking about the username you see in here for example:

C:\Users\dll64\AppData

When installing Windows it asked me to put a name for the PC but it's not being used for above, I'm guessing it's either using it from the email that I had to enter for the installation or somewhere from the account's email settings? went through the settings of the account but found nothing as such and the email linked has an extra letter that isn't used in the username in yellow.

So how exactly do I get Windows to use the username that I want like in Windows 10 where entering the username during installation would apply just the same for the system's account and files (guess Windows10 not forcing you to sign in and being able to disconnect your connection has something to do with that).

(I'm not looking to change it now but something to be applied from the start of the installation).

EDIT: Just saw this Change Name of User Profile Folder in Windows 11 Tutorial

So basically we must make a email account with a name bearing in mind that the 5 first letters are going to be the username for the files.

It's the first five characters of the Windows account you used when you first logged in after installing

If the first account you set up on installing Windows is a Microsoft account, then the user folder name is always the first five characters of the email address. If you set up a local account then the user folder is the same name as the local account.

Microsoft insist that you use a Microsoft account when first setting up a new install, but there are ways to bypass this and use a local account. This gives you complete control over the user folder name. Even if you intend to switch the local account to a Microsoft account later, the folder name will remain as you first set it.

I agree with the others but do urge you to use the tutorial procedure to do your new installation. It includes the procedure for creating a local account and it contains lots of other good advice.

MS in their wise wisdom is trying their best to make users sign-in to their MS accounts when first setting up Windows. I myself wouldn't have a problem with this if the (add your own explicit word) would let us choose our user names. Instead they use the first five characters of our email. I guess making new emojis is more important to them.
