diagnostic startup

About this tag
The diagnostic startup tag covers discussions about using Windows' selective startup mode to troubleshoot system issues. In this mode, Windows loads only basic services and drivers, bypassing third-party software. Users report problems like Internet Explorer crashing on Windows XP, slow login times on new laptops, and malware removal difficulties. Diagnostic startup helps isolate whether a problem is caused by startup programs or services. When an issue occurs in diagnostic startup but not in Safe Mode, it suggests a conflict with non-Microsoft services. This tag is relevant for Windows XP, 7, and later versions, focusing on troubleshooting boot and performance problems.
