I have been trying to uninstall a private security program now for over four hours with no success. I go through the "Settings" and the uninstall hangs at 30%. If I go through the"Run-->appwizcpl" route my computer asks if I will let MS Windows make changes to my hard drive and I allow it absolutely nothing happens. Help

    Follow these steps in order, testing the uninstall after each step.

    1. Use Windows 11/10 built‑in uninstall options
      • From Start menu:
        1. Select Start > All apps.
        2. Find the security app, right‑click it, choose Uninstall.
      • From Settings:
        1. Select Start > Settings > Apps > Installed apps (or Apps & features on some builds).
        2. Find the security program.
        3. Select More > Uninstall, then follow the prompts.
      • From Control Panel (the appwiz.cpl route):
        1. Press Windows key + R, type appwiz.cpl, press Enter.
        2. In Programs and Features, right‑click the security program, choose Uninstall or Uninstall/Change, and follow the wizard.
    2. Run the Program Install and Uninstall troubleshooter
      • If uninstall still hangs or nothing happens after UAC consent, run the Program Install and Uninstall Troubleshooter mentioned in the Windows apps removal article. It is designed to fix broken installer/uninstaller registrations and can often force‑remove stubborn programs.
    3. Boot into Safe Mode and try again
      • Some security software protects its own services and drivers while Windows is running.
      • Boot to Safe Mode, then repeat the uninstall from Settings or Control Panel. With services not fully loaded, the uninstall often completes instead of hanging.
    4. Avoid manual file deletion unless necessary
      • Manually deleting program folders is risky and can damage Windows if the wrong files are removed.
      • If considering manual removal because the uninstaller is broken, first create a system restore point, then move any personal data out of the program’s folder before deleting anything.
      • If files cannot be deleted, it usually means a process (often antivirus) is still using them; that same process may be what prevents a normal uninstall.
    5. If the vendor provides a removal tool
      • Many security vendors provide their own dedicated removal/cleanup tools when the normal uninstall fails. Check the vendor’s support site for an official removal tool for that specific product and run it as administrator.
    6. Ensure Windows Defender is active afterward
      • When third‑party security software is removed, the system can be left unprotected.
      • Confirm that Microsoft Defender Antivirus and Windows Firewall are enabled after uninstalling the old product.

    If none of these steps work and the uninstaller always hangs, the safest next options are:

    • Use the vendor’s dedicated removal tool if available, or
    • Perform a Windows repair/reset while choosing the option to keep personal files, which reinstalls Windows and removes problematic apps while preserving data.

    Hi Raelyn,

    What is the 3rd party software?

    Sometimes the developer has their own

    removal tool to uninstall it.

    Hi Raelyn Maddox,

    Some applications have error during installation process, so they cannot be removed by their official uninstaller.

    You may try some third-party uninstaller such as Revo Uninstaller, IObit Uninstaller, Geek Uninstaller, etc. to see if they can remove the application completely.
