Which recovery tool in Windows fixes and scans computer problems that prevent the computer from booting?

Startup Repair is a specialized recovery tool in Windows designed to address and fix issues that prevent a computer from booting properly. When a user encounters startup problems, such as getting stuck on the Windows logo or encountering error messages, Startup Repair can automatically diagnose and resolve common problems related to system files, boot configuration data, and disk issues. It performs a series of checks and repairs that can restore the operating system to a functional state, allowing the user to boot successfully into Windows.

In contrast, System Restore focuses on returning the system to a previous state by undoing changes made to the system files, applications, and registry. While this can help resolve issues caused by recent changes, it does not specifically target boot-related problems. Disk Cleanup is a maintenance utility aimed at freeing up disk space by removing unnecessary files, and it does not fix boot issues. Task Manager is primarily used for managing running applications and processes, and while it can help identify resource-intensive processes that may affect system performance, it does not have tools for repairing boot issues.

Thus, Startup Repair is the appropriate tool for resolving boot problems in Windows.
