I installed Windows 10 on one of my PCs when the machine was offline. So Windows created a local account. Later when that device went online, I linked it with my Microsoft account, but now that account doesn't have the same users-folder name as it has on my other PCs.
On the machines where I was online during the installation of Windows 10, the user-folder is "C:\users\email", and I want to have the same name on this new machine, where the folder-name now is C:\users\Martin.
What is the most simple solution to restore the default folder-name (C:\users\email) that Windows 10 automatically creates when you don't create a local account during installation, without installing everything again?
Thanks in advance!
Edit: this is not about how to just rename the account. I want to know how to make Windows create the default name of the user-folder, like it would do if I'd used my Microsoft account during the installation.
