Many people often get into trouble when they try to change user on Windows 10 or lower rank systems. This mainly applies to those cases when it is required to rename the user's registration data, and not log in under another registered account. Nevertheless, we will consider several general solutions for all possible situations, which will give an understanding of the procedures performed in full.
How to change user in Windows 10 with switching to another registration?
For starters, let's assume that there are multiple user accounts on the same terminal. Changing the user in Windows 10 to use a different account is fairly easy. To do this, you just need to log out of the current "account", and then log in through another registered profile.
ForYou can use the Start menu to log out from the Shutdown section.

It's just as simple when only the "Desktop" is displayed on the screen (all active applications are minimized or closed), you can use the combination "Image" + F4, after which you activate the user change item. On the start screen that appears, select another account and enter a password, if necessary.
How do I change my username in Windows 10 for self-login?
But this was a standard situation, which does not affect some other actions with "accounts". It can be assumed that for some reason you need to change the user in Windows 10 by renaming the user. To access these options in the current account, you can use the avatar located in the Start menu or access the appropriate section by typing the abbreviation netplwiz in the Run console.

Select the desired entry, press the properties button, enter a new name and save the changes. In order to avoid problems and failures, it is better to enter names using the Latin alphabet.
In the same way, you can easily change the user in Windows 10 with renaming the registration record through the "accounts" management section located in the "Control Panel".

Here you just need to click on the name change link, enter a new name and save the changes. If asimilar actions need to be performed for another account, select the control point for another account.
Creating and deleting accounts
You can try to change the user when you sign in to Windows 10 so that your current registration is not displayed at all. For such purposes, the easiest way is to create a new account in advance using the above section in the "Control Panel", and then delete the old registration by first logging in under the new "account".
Note: it is desirable to create an administrator account. If this is not done, then you will have to change the type manually or include the new account in the administrators group.

You can change the administrator name directly in the group policy options settings (gpedit.msc), as shown in the image above.

Similar procedures are provided in the options menu, however, in general, the settings presented in this section are best used to change the login not under a local account, but through a Microsoft account.
How do I change my computer name?
Finally, let's see how you can completely change the current name of your computer device, because even when you first install Windows, this name is assigned automatically.
The easiest way to perform such actions is in the advanced system settings from the properties of the computer, where you need to enter a new name in the description field(again, in Latin).

If your terminal is connected to a local network, similar actions must be performed after pressing the change button in the workgroup block. But it is not recommended to change the name of the working group itself if there is a local network connection.
