Corrupt user profile on Windows: Quick fixes

Signs of a corrupt user account on Windows include lost administrator permissions, slow performance due to high disk drive issues, restricted login access and more. If you notice any of these problems, we recommend follow each step below.

Even if it appears to be fixed, it’s best to run an antivirus scanner to detect any malware hiding in plain sight.

  1. Update your software and restart your computer

    Updating your Windows PC software and restarting your computer can often fix problems with your user account. However, they can also fend off malicious software. 

    Cybercriminals take advantage of security vulnerabilities on your device. These zero-day vulnerabilities allow threat actors to exploit computer systems until developers mitigate them, which can cause major damage. 

    Updating your system’s software can resolve the issue. A software update often contains security patches that help protect your device, as developers work to protect users from known zero-day attacks and other forms of malware trying to infect your device, especially with unfamiliar processes. 

    You can update your device through its settings. For example, you can update your Windows PC by navigating to Start > Settings > Windows Update > Check for updates. If there are any, download and install the update. 

  2. Create a new administrator account

    If you’re having problems with your usual user account, such as lost administrator rights, try creating a new admin account instead. 

    To do this, you’ll need to restart your computer in Safe Mode. There are a few ways to do this, but a simple way is to head into Settings.

    Type in “Change advanced start-up options” in the search box located on the taskbar. Under Recovery, click Restart now next to Advanced startup. Then click Restart now.

    From here, go to Troubleshoot > Advanced options > Startup Settings > Restart. Using the number keys, select Enable Safe Mode.

    Once done, type “Command Prompt” in the search box on the taskbar. In this window, type in:
    net user <username> <password> /add

    Replace the <username> and <password> with ones of your choosing for the new account. 

    Then, use the Command Prompt to type in the following command:
    net localgroup administrators <username> /add

    This will add a new user account with admin rights. You can use this account from now on.

  3. Use the built-in Windows repair tool

    An easy way to fix any corrupt files or applications that are causing problems with your user account is to use Windows’ built-in repair tool. This is know as the DISM command tool.

    To run in, type in “command prompt” in the search box on the taskbar and open the app. From there, type in the following:
    DISM.exe /Online /Cleanup-Image /RestoreHealth
    Then press Enter.

    Your Windows PC will automatically scan your system for any corrupt files and fix problems it comes across.

  4. Change your passwords

    If you’ve noticed you symptoms of a corrupt Windows account, chances are your PC has been infected with a virus or malware, and your online accounts and devices are at risk of being compromised.

    To help mitigate potential malware threats or hackers taking control of your accounts, change your passwords and use a strong password to stop suspicious activity. 

    Using password managers such as LastPass or 1Password can help manage all your passwords in one place, create a complex, near-unbreakable master password and encrypt your information. 

    Changing passwords will stop hackers from trying to steal any sensitive information and your online accounts.

What causes a corrupt user profile on Windows?

Your user account on Windows lets you access your files and data. If it’s running slow, keeps crashing, shows corrupt files or won’t let you perform specific administrator tasks, your user account may be corrupt.

An accidental change in important user profile files in system settings can cause problems with your account. However, sometimes, a software bug or a power outage can mess with your PC, which can randomly cause your user profile to act strangely.

The real cause for concern is when malware has purposely changed your user profile, possibly making it inaccessible. A hacker can cause significant damage to your system and your private information if malware has taken control over the account.

Malware can sneak onto your device through a number of ways, including mistakenly clicking a suspicious link in an email or going to a dodgy website, thanks to phishing attacks.

To identify and remove malicious software and prevent infections from happening, it’s best to use an antivirus like Norton 360 to detect any malicious activity and stop the malware from causing more harm.

Hundreds of malware emerge every minute, and it’s Malwarebytes’ mission to detect and conquer them all. Does the antivirus do this successfully? Yes, but there’s wiggle room for improvements.
