How to Change Administrator Account in Windows 10 [Tutorial]
Windows 10 has a standard user account and an administrator account. Both accounts have different rights to use a device and applications.
An administrator account provides full system control with privileges such as access to all files on the device. You can also customize other user accounts and change them to Standard or Administrator, install software and hardware, change security settings, and perform elevated tasks.
However, if you get locked out of your computer, forget your administrator password, or have your administrator rights accidentally revoked, you will no longer be able to make any changes to the device.
