Generally if your computer is not able to start, the Windows7 operating system will automatically enter the recovery function, that is, a gray progress bar appears. I believe this interface should be familiar to everyone. This is the Win7 flagship version of the system repair feature, "Start Repair" is designed to diagnose and repair problems that prevent Windows from starting, thus avoiding time-consuming reinstallation procedures. Startup Repair was originally introduced in Windows Vista, and now Windows 7 automatically installs the Startup Repair tool on the operating system partition so that you can access it at any time. If you encounter an unsuccessful startup, Windows 7 automatically loads startup fixes that scan your computer for problems such as registry corruption, missing system files, or invalid startup configuration data, and automatically fix them if possible, and then reboot as usual. Detailed information about the actions that should be performed when you use the Startup Repair feature and the feature does not start automatically. The following small series will explain the function of the Windows7 system Recovery option.
1 Startup Repair
Fixes some issues that may prevent Windows from starting correctly, such as missing or corrupted system files.
2 System Restore
Restore your computer system files to an earlier point in time without affecting your files (for example, e-mail, documents, or photos). If you use System Restore from the System Recovery Options menu, you will not be able to undo the restore operation. However, you can rerun System Restore and select other existing restore points.
3 System Image Recovery
You need to create a system image in advance to use this option. A system image is a personalized, partitioned backup that contains Windows, programs, and user data (such as documents, photos, and music).
4Windows Memory Diagnostics Tool
Scans the computer for errors in memory. For detailed usage of the Windows7 Memory Diagnostics tool, see: How to use the WINDWS Memory Diagnostics tool to check for memory reliability.
5 Command Prompt
The Windows7 command prompt is available to advanced users. I'm sure you remember how to install a new Windows7 in an XP system, using a command prompt. Call the Win7 standard installer directly from the command prompt to invoke the hard disk partitioning feature in the Setup program.
The above five features are a feature introduction to the Windows7 system Recovery option. Later in our tutorial, we will provide a lot of details about how to use these features.
