Intune remediation refers to the process of using Microsoft Intune to automatically detect and fix common issues on managed devices. This is achieved through remediation scripts, which consist of a detection script to identify problems and a remediation script to resolve them. These scripts help maintain device compliance and security by addressing issues proactively, often before users even notice them. By leveraging Intune remediation, IT administrators can reduce support calls and ensure a smoother, more secure IT environment.
I have already written an article about remediation scripts you can check it from this link :

Thanks
