Every computer running on Windows 10 (and all other versions of the OS) has a built-in Administrator account. This is the account users find when they boot their computer up for the very first time. The built-in Administrator account can be personalized and then used like any other user account, and it can also be deleted and replaced with a local user account or Microsoft account. The good thing about a built-in Administrator account is that it is not subject to the same laws and restrictions as Standard accounts and normal Administrator accounts in Windows 10.
There are certain limitations to the extent of change that can be brought about on a Windows 10 computer using a Standard account or an ordinary Administrator account, and even then the user has to jump through a lot of UAC (User Access Control) hoops. However, the built-in Administrator account’s capabilities are boundless – users can do anything they like, change anything they like and access anything they want to when logged into a built-in Administrator account. If, by any chance, a Windows 10 user deletes their built-in Administrator account, there is no reason to fret as it can just be re-enabled by right-clicking on the Start Menu button to open the WinX Menu, clicking on Command Prompt (Admin), typing in the following command and pressing Enter:
net user administrator /active:yes
Note: The built-in Administrator account is named Administrator by default. In the event that you changed the name of the built-in Administrator account before you deleted/disabled it, you are going to have to replace administrator in the command-line above with what you renamed the built-in Administrator account.
Being able to make any changes you like to your Windows 10 computer and being able to access anything you want to without ever having to be prompted for confirmation or your password by UAC is pretty neat. However, using a built-in Administrator account can sometimes go south and you can get stuck in it for good, especially if the Administrator account was the only user account you had on your computer. Users affected by this issue are stuck in their built-in Administrator accounts in the sense that they can’t create a new account for themselves by going in to Settings > Accounts > Family & other users and using any of the two options for user account creation provided.
Most people would think that being stuck in an all-powerful Administrator account in which you can do anything without ever having to deal with UAC or any other restrictions is a pretty sweet deal, but, in reality, it isn’t. A side effect of this issue is that affected users lose their ability to launch built-in applications and programs such as Microsoft Edge and Calculator, receiving a message stating that the “app can’t be opened using the Built-in Administrator account” every single time. This side effect takes this issue from ‘blessing in disguise’ to a total nightmare. Thankfully, though, it is entirely possible to fix this issue, and here’s what you need to do in order to do so:
Right-click on the Start Menu button to open the WinX Menu.
Click on Command Prompt (Admin).
Type the following into the elevated Command Prompt, replacing Username with what you want the new user account to be named, and press Enter:
net user “Username” /add
Once this command has been executed, a new Standard user account with the name you designated in the command will be created.
Once you have created a new Standard user account, you need to turn it into an Administrator To do so, type the following into the elevated Command Prompt, replacing Username with what you named the new user account, and press Enter:
net localgroup administrators “Username” /add
Log in to the new Administrator user account.
Repeat steps 1 and 2 to create a new elevated Command Prompt.
Next, you need to turn the built-in Administrator account into a simple Standard user account. In order to do so, type the following into the elevated Command Prompt, replacing Administrator with the actual name of the built-in Administrator account (if you had changed its name in the past), and press Enter:
net localgroup users “Administrator” /add
Once the command-line described above has been successfully executed, you will not only have two user accounts on your computer but will also be able to launch built-in Windows 10 programs on your old built-in Administrator account which is now just an ordinary Standard user account.
