Microsoft has always made updates to its security and analysis tools. In addition to device security, there is system security, which has features available in the Windows operating system. The security parameters that have already been configured and are ready to be deployed on your devices are included in the security lines. Microsoft's Antivirus Microsoft Defender, which is built into Windows, allows you to protect your devices with next-generation security. Among the changes, we note the addition of a new menu, Start, in the center of the taskbar. It is still feasible to return the menu to its original place in the bottom left corner, which it has held since its inception. Windows 11 programs such as Notes, Photos, Paint, and the File Explorer have all been updated to better integrate with the rest of the system.
