The error “Your IT administrator has limited access” can be caused by third-party antivirus software and appears if you have recently updated your Windows 10 and try to activate Windows Defender. As you can see from the error itself, it appears when you try to activate Windows Defender all the time without permission. There are several ways to solve this problem, so don’t worry.

Users receive the following error message:

Your server administrator has limited the number of items you can open at the same time. Try closing open messages or deleting attachments and images from unsent messages you write.

Disable the Windows SmartScreen function

First, we recommend that you disable Windows SmartScreen (officially called Windows SmartScreen, Windows Defender SmartScreen and SmartScreen Filter), a cloud-based antiphishing and anti-malware component that is included in many Microsoft products, including Windows 10. It determines whether a downloaded application or application installation program is potentially malicious by checking the downloaded files against a list of websites and reported malware that are known to be insecure.

July 2020 Update:

We now recommend using this tool for your error. Additionally, this tool fixes common computer errors, protects you against file loss, malware, hardware failures and optimizes your PC for maximum performance. You can fix your PC problems quickly and prevent others from happening with this software:

  • Step 1 : Download PC Repair & Optimizer Tool (Windows 10, 8, 7, XP, Vista – Microsoft Gold Certified).
  • Step 2 : Click “Start Scan” to find Windows registry issues that could be causing PC problems.
  • Step 3 : Click “Repair All” to fix all issues.


It also analyzes downloaded files against a list of known files downloaded by many Windows users. If the file is not in this list, SmartScreen displays a warning to be careful. This feature may be responsible for the error you see and will prevent the application from installing. If this is the case, disable SmartScreen and check to see if the error persists. To disable SmartScreen, go to Search, type smartscreen, then click on the App & Browser Control result to open it.

Disable/uninstall third-party antivirus software

Only one antivirus software works on the computer at a time. If you have installed third-party antivirus software, Windows Defender is automatically blocked. It is never recommended to use multiple antivirus applications on the same computer. They never play well together. Most of them will try to uninstall or disable the competing products they detect during installation. In fact, most enterprise audiovisual solutions cannot be installed on a system running another audiovisual product (there are exceptions).

If you want to use Windows Defender, we can uninstall the third-party antivirus software and restart the computer, then review the symptom.

Using a hidden administrator account

When you install Windows on your computer, a hidden administrator account is automatically created. This account is usually used by Microsoft support or other technicians when you report an error that you report to them. Therefore, to use its privileges, activate Windows Defender via the account. How to connect:

  1. Press Winkey + X and select’Command prompt (Admin)’.
  2. At the command prompt, type : net user administrator /active:yes
  3. This command activates the hidden account so that you can log in to the login screen.
  4. Log out of your account and log in to the hidden administrator account.
  5. Now try to reactivate Windows Defender.

Please be careful not to use the account under normal conditions as it may be risky. Use the following command to deactivate the account:

net user administrator /active:no
