How to quickly restore XP system registry
WinXP system registry Quick Restore method:
1. Restart your computer, and then press the "F8" key when you see the "Select Startup operating System" message.
2, use the arrow keys to highlight the Last known good Configuration, and then press ENTER. Num LOCK must be turned off, and the arrow keys on the numeric keypad will work.
3. If you have a dual-boot or multiple-boot system, use the arrow keys to highlight the operating system you want to start, and then press the "Enter" key.
When Windows is successfully started, the registry reverts to its state when the computer was last successfully started. Selecting the last Known Good configuration is a way to recover a system from a problem, such as a newly added driver that does not match the hardware, but it does not resolve the problem caused by a corrupted or missing driver or file. and Windows restores only the information in the top hklmsystemcurrentcontrolset of the registry, and any changes made in other registry keys remain unchanged.
