Windows 10: Suddenly lost Administrator rights on Windows 10

I've explained this several times to different people so I'll keep it short. Basically I was installing my new digital art tablet and it wouldn't let me. My PC tells me I'm not an Administrator, and I'm suddenly a Guest Account on the PC i've been an Admin on for years. For example, if I try to "run as administrator", I run into this:


To continue, enter an admin user name and password. The only option is "No" with the "Yes" grayed out. I've tried a few things to fix this and I manage to run into a dead end each time. How do I fix this?

Lost administrator rights

Hi Scott,

Thank you for posting your query in Microsoft Community.

I understand that you have lost administrator rights on the computer to perform any action and I will be happy to answer your query. Let me ask you;

• When was the last time you had administrative privileges?
• Do you remember making any specific change in the computer prior to the issue?
• Did you use Microsoft Account to sign-in to the computer in the past?
• As you say that you never used any password, do you mean to say you have been using local account?
• Which security software is installed in the computer?
• What is the make and model of the computer?

There could be several reasons for this cause including any system file corruption, viruses etc. Let's try the following methods and check.

Enable built in administrator account while logged in to safe mode

Step 1: Start your computer in Safe mode from the Windows Recovery Environment

a. When you hit the power button, hold down the
Shift key when clicking the Restart button.

b. The next screen will present you with three options. Click
Troubleshoot.

c. Next, hit
Advanced options followed by Windows
Startup Settings from the next screen.

d. Your PC will now be rebooted to enable the advanced parameters, which include Safe Mode as well.

Step 2: Once you have entered into the Safe mode then, open Command Prompt and enable Built in Administrator.

Follow the below steps to enable Built in Administrator:

• Open Command Prompt from Windows Recovery Environment.
• Copy and paste the below command and press Enter.

net user administrator /active:yes

3. Close the Command Prompt.

4. Try to login though Built in Administrator and convert the your user account to Administrator or you can create new user account.

Step 3: Apply administrator right

Step 4: You may also create a new user account with administrative rights and check

Press Windows key + R to open

Type control userpasswords2 and press
OK

Under User Account window and under
Users tab, click Add tab

Under How will this person sign-in windows, click the option at the bottom
Sign in without a Microsoft account (not recommended)

On the next window click Local Account
at the bottom

Choose a user name (use password if you want to or you can leave the password section blank as it is just to test)

Click Next and then click
Finish

As you click Finish, the previous User Accounts
window remains on the screen

Select newly created user and click Properties

Click Group Membership tab

Click to select Administrator and click
