I have extensive experience in deploying and imaging Windows operating systems using tools like Microsoft Deployment Toolkit (MDT) and Windows Deployment Services (WDS). I've automated the deployment process to ensure efficiency and consistency across multiple devices, incorporating driver management, application installation, and system updates into the imaging process. This has significantly reduced deployment times and improved system reliability.

To troubleshoot a Windows system with performance issues, I start by analyzing the Task Manager and Resource Monitor to identify high resource usage. I check for malware, unnecessary startup programs, and outdated drivers. If needed, I use Performance Monitor and Event Viewer for deeper diagnostics. Based on findings, I may clean up disk space, defragment the hard drive, or adjust system settings to optimize performance.

I have managed Group Policy Objects (GPOs) to enforce security settings, deploy software, and configure user environments across Windows domains. I've designed and implemented GPOs to streamline administrative tasks, ensure compliance with company policies, and enhance system security. Troubleshooting GPO application issues and optimizing policy processing are also within my expertise.

I ensure Windows systems are secure by regularly applying patches and updates through WSUS or SCCM, configuring Windows Defender and firewall settings, and implementing least privilege access controls. I also monitor for vulnerabilities using tools like Microsoft Baseline Security Analyzer and enforce encryption and strong authentication methods to protect data.

Before upgrading, I assess software compatibility using the Windows Upgrade Assistant and Application Compatibility Toolkit. I test critical applications in a controlled environment and work with vendors for updates or alternatives if compatibility issues arise. Documenting and communicating changes ensures minimal disruption to users.
