System administrators, as well as home users, need to run various diagnostic tasks in Windows from time to time to resolve or bypass system problems. Last year, Microsoft published a how-to document with various such native Windows applications, tools, and utilities, such as Task Manager, Registry Editor, and more.
Apart from these, Windows also has SFC (System File Checker) and DISM (Deployment Image Servicing and Management) to scan and repair corrupted or missing files from the system.
