System error user name this method is regret

Today, a small partner asked how to change the Chinese username to English in Windows 10. Actually, changing the username is quite simple, but the real challenge comes when you need to ensure that all folders and user data under the original Chinese name are properly updated as well. Many users choose to use their Chinese names for simplicity or just for "personality," which can lead to messy folder structures. That's why I've put together a complete solution to fix this issue once and for all.

Let’s start with the installation process. If you're setting up Windows 10 without an internet connection, you'll have the option to set a custom username. However, if you're connected to the internet, you’ll be prompted to log in with a Microsoft account. Based on my experience, it's best to avoid logging in directly with your Microsoft account. Otherwise, the folder name under C:\Users will be automatically set to the first six characters of your email address, which can look really unattractive.

Okay, the warning is over. Now, if you’ve already set up a Chinese username or used a Microsoft account and ended up with an unwanted folder name, don’t worry. You can still fix it by following these steps carefully. Missing even one step might result in incomplete changes or data inconsistencies—so make sure you follow everything exactly.

First, open the Command Prompt as an administrator (you can do this by pressing Win + X). Then type the following command:

Net user administrator /active:yes

This will enable the built-in Administrator account. Once done, log off your current user and log in with the Administrator account. For extra security, consider booting into Safe Mode first before logging in.

Next, go to the C:\Users folder. Right-click on the folder you want to rename (the one with the Chinese name) and select "Rename." Change it to your desired English name.

Don't panic if you restart or switch accounts. After that, press Win + R, type "regedit" and open the Registry Editor.

Now, navigate to the following key:

HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows NT\CurrentVersion\ProfileList

Look through each subkey and check the "ProfileImagePath" value. Find the one that points to the original Chinese username folder and change it to the new path.

Make sure not to skip any steps, and avoid restarting too quickly. A mistake here could cause issues like missing files or system instability. Take your time and double-check everything.
