Windows operates fine without it and most people will never really need to use that account. However, it does offer a bit more power and flexibility than a regular user account---at the risk of reduced security. Let's take a look at the Windows Administrator account so you can fully understand what it's for.
No normal user accounts should have Administrator access to your network. Users that have Administrator access as part of their normal user account could inadvertently cause a lot of damage if (for example) they are infected by a virus that deletes data.
The administrator account in Windows 10 gives users additional system rights to make system changes or install programs without restrictions. However, as you'll have heard before - with great power comes great responsibility - so the administrator account is disabled by default.
An administrator is someone who can make changes on a computer that will affect other users of the computer. Administrators can change security settings, install software and hardware, access all files on the computer, and make changes to other user accounts.
When you delete an admin account, all data saved in that account will be deleted. For instance, you will lose your documents, pictures, music and other items on the desktop of the account.
The built-in Administrator is basically a setup and disaster recovery account. You should use it during setup and to join the machine to the domain. After that you should never use it again, so disable it.
Administrators have the highest level of access to an account. If you want to be one for an account, you can reach out to the Admin of the account. A general user will have limited access to the account as per the permissions given by the Admin.
With a Microsoft account, you can access your apps, files, and Microsoft services across your devices. If needed, the local user account can have administrator permissions; however, it's better to just create a local user account whenever possible.
If you use an email address and password to sign in to these or other services, you already have a Microsoft account—but you can also sign up for a new one at any time. An administrator/Local account is a user account that lets you make changes that will affect other users.
In Windows systems, the built-in administrator account is similar to the "root" or "superuser" accounts in other operating systems. It was originally intended to facilitate system setup and disaster recovery. It can also be used to run programs and apps before a user account is created.
An administrator account is similar to a standard account but with some additional privileges. These privileges allow you to manage system files or do anything without requiring confirmation. With an administrator account, you can also access all those files that other users own on the same computer.

The default or built-in administrator account in Windows 10 can be a security risk, especially if the person has physical access to your computer. I would suggest either delete the account or, at the least, set a strong password and then disable it again. That's one less thing to worry about.
Running a Windows OS with administrator rights allows you to install, uninstall, and make other changes to your computer. You may ask, “Why is this not a good practice?” Leaving your computer in admin mode opens you up to many security risks including viruses and malware that can potentially damage your business.
Simply put, admin accounts are the most powerful type of user. They have the power to do just about anything on a device. For context, think about the guy or girl in IT who you need to ask to perform tasks like setting up new software. Every device or system will have at least one admin user somewhere.
The default local Administrator account is a user account for system administration. Every computer has an Administrator account (SID S-1-5-domain-500, display name Administrator). The Administrator account is the first account that is created during the Windows installation.

One of the biggest differences between a local account and a Microsoft account is that the former is exclusive to the Windows PC you created it on. A Microsoft account exists on the internet, and you can access it on a range of devices, including computers, phones, and the Xbox family of consoles.

The administrator account on a Windows PC gives you a safe user environment to perform maintenance tasks on your PC. For example, if you want to allow someone to fix a problem on your PC, you could enable the administrator account on Windows 11.
You can have two administrator users, you can even have 3, or more if you want. You don't need to be internet connected for a Microsoft account login to function. I always make second local admin user with a simple password that I wont forget. Visitor with admin privileges .
