De-Enshittify Windows 11: Make Windows 11 More Secure ⭐

Windows 11 offers a mix of security and privacy features, with a recommendation for users to opt for a Copilot+ PC with a Qualcomm Snapdragon X-series processor for enhanced security. Most users log in with a Microsoft account, which provides benefits such as two-factor authentication, device-bound passkeys, account recovery options, and automatic disk encryption. However, using a local account poses security risks, including limited recovery options and lack of support for key security features. To secure Windows 11, users should take several steps during initial setup or later, including enabling Windows Security features, verifying device encryption, and enhancing sign-in security through Windows Hello options like facial and fingerprint recognition. Additional security features such as Controlled Folder Access and Smart App Control can be configured for better protection. Users are advised to remove unnecessary third-party security apps and keep Windows 11 and installed applications up-to-date to maintain security. Regular updates and proper configuration of Windows Update settings are also essential for preventing disruptions and ensuring data safety.

How to Install McAfee Antivirus on Windows 11 or 10

Installing third-party antivirus software like McAfee on Windows 11 can be challenging due to the built-in Windows Security, which can complicate the installation process. Users may face issues such as silent failures from conflicting software, permission problems on restricted machines, or restrictions due to S Mode on new laptops. Windows 11 includes Windows Security, which is effective for malware protection, but McAfee may be necessary for compliance, additional features, or centralized protection for multiple devices. McAfee supports Windows 11 Home, Pro, and Education editions but not Enterprise. The minimum hardware requirements include a processor of 1 GHz or faster, at least 2 GB of RAM (4 GB recommended), 1.3 GB of free disk space, an internet connection for download and updates, and a display resolution of at least 1024×768. McAfee requires a persistent internet connection for activation and updates. Before installing McAfee, users should check if their device is in S Mode, as McAfee cannot be installed in this mode. They must remove any existing antivirus software completely, as leftover files can interfere with the installation. Users should also ensure that Windows 11 is up to date and verify that there is enough disk space available. To download McAfee, users should go directly to the McAfee trial page to avoid scams. After downloading, they need to run the installer and restart their computer after installation. Users should then activate McAfee, run a manual update, and conduct a full system scan. Common installation problems include freezes during download, errors due to S Mode, and issues with Windows Security not recognizing McAfee as the active antivirus. Users can verify that McAfee is functioning correctly by checking the system tray icon, Windows Security settings, and the McAfee dashboard. To uninstall McAfee, users should go to Settings > Apps > Installed Apps, select McAfee, and follow the prompts to remove it. After uninstallation, Windows Security will reactivate automatically. McAfee offers several plans for Windows users, including Basic, Essential, Premium, and Advanced, each with different features and device limits. The Basic plan is suitable for single-device users without additional needs, while families may benefit from the Essential or Premium plans.

Windows Security is a built-in antivirus that activates automatically after McAfee removal, providing protection.

How to Disable Windows 11 Defender: Temporary and Permanent

Microsoft Defender Antivirus is the built-in security solution for Windows 11, protecting against viruses, malware, and ransomware. Users may need to disable it temporarily or permanently for various reasons, including software installation, penetration testing, performance issues, transitioning to third-party antivirus solutions, or troubleshooting conflicts. Temporary disabling can be done through the Windows Security app, which will automatically re-enable after a restart. Permanent disabling requires changes in Group Policy, applicable only to Windows 11 Pro, Enterprise, and Education editions, and necessitates disabling Tamper Protection first. Another method for permanent disabling is installing a third-party antivirus, which automatically deactivates Defender's real-time protection. Windows 11 Home users cannot use Group Policy for permanent disabling but can still temporarily disable Defender or install a third-party antivirus. Disabling Defender exposes the system to threats, and users should ensure they have alternative protection in place. Major Windows updates may reset Defender settings, and caution is advised when modifying system settings.
