The Windows Registry Editor is accessed by pressing Win-R, typing regedit, and confirming with “OK.” The registry files are located in “C:WindowsSystem32config” and user-specific files in “C:Users[username].” The five main branches of the registry are: - HkeyCurrentUser: Configuration settings for the current user. - HkeyLocalMachine: Global settings for all users, requiring administrative rights for changes. - HkeyUsers: Contains user IDs for system profiles. - HkeyClassesRoot: Manages file name extensions and program shortcuts. - HkeyCurrentConfig: Links to keys under HkeyLocalMachineSystemCurrentControlSetHardware ProfilesCurrent. Users can create subkeys and values, which can be of different types. To modify the registry, select a key, use the “New” context menu, and double-click to edit. Creating a backup of the registry is recommended before making changes, which can be done using the Registry Backup Portable tool. To restore the registry, select the most recent backup and click “Restore Now.” Microsoft’s Process Monitor can be used to analyze registry values by filtering for “RegSetValue” and tracking changes. Certain registry values are restricted from modification for security reasons, such as the “widgets” feature in Windows 11. However, methods like batch files and PowerShell scripts can override these protections. Windows transmits diagnostic data to Microsoft, impacting user privacy. Tools like O&O Shutup10 and W10Privacy help manage telemetry settings.
