The Startup Repair tool automatically fixes many common problems. The tool also lets you quickly diagnose and repair more complex startup problems. When the computer detects a startup problem, the computer starts the Startup Repair tool. When the tool starts, it performs diagnostics. These diagnostics include analyzing startup log files to determine the cause of the problem. When the Startup Repair tool determines the cause, the tool tries to fix the problem automatically.

When a startup problem occurs and the Startup Repair tool cannot fix the problem, the system returns to its last known working state. If the Startup Repair tool cannot automatically recover the system, the tool gives you diagnostic information and support options to make troubleshooting easier.

The Startup Repair tool generates a log file to help you understand the startup problems and the repairs that were made. You can find the log file in the following location:

Here, %windir% is the folder where Windows is installed.
