It adopts a hierarchical structure, including multiple root keys such as HKEY_CURRENT_USER and HKEY_LOCAL_MACHINE, which saves user and system-level settings respectively. The registry records various data associated with the file to the hardware configuration, and if the registry is corrupted, it may cause system exceptions. To open the Registry Editor, press Win R to enter regedit and press Enter. Careful action should be taken when editing the registry. It is recommended that 1. Back up the registry first; 2. Do not delete unknown items at will; 3. Make sure to understand the role of modifying the content; 4. Use administrator permissions to run the editor. Common operations include finding, modifying, adding or deleting key values, but incorrect operations may cause serious problems, so novices should modify them under clear guidance or use third-party tools to assist in completing them.
