I found "Unknown account" in the list of user profiles that can be traced from the system properties.

It is a big size of 2.58GB.

A Windows user profile is a collection of information and files associated with an account.

[For example...]

account name
password
OS and application software setting information
Files and folders created by the user
...etc

Local user profile (PC local drive)
Roaming user profile (eg Windows Server)

Roaming user profiles are set up by your system administrator. PC under Windows Active Directory (domain) must not execute the procedure described here.

Well, the main subject.

I have deleted the "unknown account" found in my user profile so I will post the steps I took and a snapshot.

If you follow the steps below, there is a possibility that your favorite features of Windows Explorer may be broken, but I am also writing about how to fix it.

If you have plenty of room on your local drive, you don't need to follow these steps.

The identity of the unknown account

A user profile is a collection of important Windows files created for each logged-in user.

It is not supposed to be deleted, but there is a Delete button.

...??...

The unknown account is a remnant of the account that was deleted from Windows 7.

[Create account｜Delete]

Create a new account
A user profile with the account name is created
Delete account
The user profile associated with the account remains on the PC hard drive as an "unknown account"

Summary

You can delete unknown accounts, but please be aware that deleting them may cause problems.

Right-click "Favorites" in the left pane of Windows Explorer
Select "Add Current Location to Favorites"
Not added to favorites

The above example

This was because the newly created account was accessing some files stored in the unknown account folder.

The Favorites folder is a Windows system folder and must be initialized to recover.
