Why Should You Delete the Win­dow 10’s Built-in Admin Account and How to Do It

Gaurav Bidasaria

All Windows 10 computers come with a built-in administrator account. This is not the same admin account that you created during the Windows installation process. This is different. It's the default one that is usually targeted by hackers to gain access and control of your computer. That would make you wonder whether you should delete the default built-in admin account or not.

Most users don't even know about that account, as folks seldom go around looking for it unless something breaks. Even when you are creating new user accounts or switching from one to another account. But that doesn't mean it isn't there. Let's understand everything in more detail and determine how to delete this admin account and why you should consider doing so.

Built-In Admin Account in Windows 10

The built-in admin account is called the Administrator. Pretty unimaginative name, but okay. This account was available to use in Windows XP and previous versions, but Microsoft disabled it, citing security reasons after Vista. If anyone can enable and access this account remotely, he/she gains complete control of your computer. What's interesting is that this account is not password protected but only disabled. Admin accounts have full privilege leading to security risks in case of a breach. In case you choose to enable this account, remember to create a strong but random password to protect it.

The only situation where this admin account will come in handy to you is when you are locked out of your current admin account. It has known to happen, and reasons could include accidental deletion or any thing. Some users forgot their password. This is why we recommend creating two admin accounts and using a guest user account for your regular work.

Even then, the built-in admin account will be useless unless you have enabled it. I would rather delete the default account and create a new one, giving me more control over the account's name and password. Leave it disabled if it is not bothering you much but don't enable it and then leave it unsecured.

Why does it exist in the first place? It is created for system builders and service technicians who use it to make system-level tweaks before the finished product is sent to you digitally or via mail.

How to Enable/Disable Built-in Admin Account

There are a few ways to do it like using Registry Editor, Command Prompt, Computer Management, and Group Policy Editor. The last option is not available to Windows Home users. We will discuss only two here to keep this guide short and simple.

Command Prompt

Step 1: Search for and open Command Prompt from the Start menu by clicking on Run as administrator.

Note: Noticed there is also an option to set a password there on the menu? Another way is to enable the admin account, set a really strong password, and then disable the account again. That will reduce the associated risk.

Step 3: Check the Account is disabled box to disable the account. That is the default position, as you will notice in the screenshot below.

Access Denied

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. Create an additional admin account with a different password to make sure you are never locked out of your computer. Use a guest user account for daily use to prevent giving programs or apps admin rights to the said account by default. Even if the guest account is compromised, you don't have much to lose.
