When using Windows, you may notice that your user folder under C:\Users does not match your preferred username. This can happen if the account was created with a different name or email. While it may seem simple to rename the folder, doing it incorrectly can break your system.
In this guide, we’ll show you the safe way to change your user folder name without causing issues.
