Registry Scan

The Registry Scan (Scan tab) consists of the following options: a Registry Scan, Scan Results, and Ignore List. Each of these options is explained below:

  • Registry Scan - The Registry Scan is a process that scans your computers registry and checks for registry errors, partial uninstall's, duplicate entries, invalid path references, etc. To begin a registry scan, start by selecting the items you would like to scan. Check the box (√) if you would like the item to be scanned by RegDefense, or uncheck (X) the box to exclude the item from being scanned. By default, each of the items below are selected for the registry scan:

    • Com/Active X Entries: Windows Registry includes a COM/ActiveX section which may have invalid entries that can cause application failure, system crashes, or errors when opening documents.
    • Uninstall Entries: Windows Registry includes an Uninstall Entries section which may have invalid entries or point to one or more missing entries. Usually this is caused by incorrectly installing or uninstalling programs and applications.
    • Font Entries: Windows Registry includes a Font section which may include one or more missing font files that can cause errors in applications (for example, word processing applications).
    • Shared DLL's: Windows Registry includes a Shared DLL's section which may contain invalid entries that cause application failure due to DLL conflict.
    • Application Paths: Windows Registry includes an Application Paths section which may include invalid disk directories that can cause application failure and result in a crashed computer.
    • Help File Information: Windows Registry includes Help Files which may point to invalid help files that can cause application help files to open incorrectly.
    • Windows Startup Items: Windows Registry includes a Run section which may contain missing program entries that can be caused by incorrectly installing or uninstalling an application.
    • File/Path References: Some registry issues may be linked to files that don’t exist and folders that are temporary files and are used for storage.
    • Program Shortcuts: Program shortcuts with a ".ink" extension, may no longer be linked to an application.
    • Empty Registry Key: Registry keys may be empty which means they have no associated value.
    • File Associations: Windows Registry includes a File Associations section which may contain invalid file associations. When files are associated with programs that don’t exist they show up as an irregularity.
    • History: Depending on your computer settings, it may be storing history for deleted programs. Doing this uses unnecessary resources to store information.
    • Program Associations: The Windows Registry often includes invalid software links or entries. Managing these entries can free up computer resources and increase computer speed.
    • System Drivers: This portion of your registry can contain links to invalid or corrupt driver entries such as printers, thumb drives, storage devices, etc.
    • Firewall Rules: Windows OS contains a built-in firewall settings/rules that overtime can contain invalid or unnecessary registry entries.
  • Following a registry scan, the scan results are displayed as a total number of errors found. Based on the number of errors found, your computer is then given a registry health rating. Results are also grouped by category, and you can explore each category by clicking the plus sign (+). Use the corresponding ignore link if you wish to have items overlooked and added to the Ignore List. You can complete the registry scan by clicking the Fix button to fix the registry items selected for repair.
  • Scan Results - The Scan Results tab displays the total number of registry Errors, number of items Cleaned, and number of items Ignored returned from the Registry Scan.

    • Errors: The Errors represent the total number of items detected by the Registry Scan.
    • Cleaned: Reflects the total number of registry errors repaired after clicking the Fix button.
    • Ignored: Displays the items that were manually added to the ignore list or in some cases they may include items that were automatically ignored by RegDefense. Items may be ignored automatically by RegDefense if your OS or another application is denying access to the registry item.
  • Ignore List - RegDefense has an internal ignore list that ensures compatibility and third-party application support amongst RegDefense users. Users may also add items to this ignore list following any registry scan. Keywords can be added manually using the Add Keyword feature. Adding a broad keyword like "Microsoft", would exclude all Microsoft related registry items. We recommend that you refine your key word like "Microsoft Outlook", when adding custom keywords to the ignore list.

Backup & Restore

Each time you use RegDefense to repair registry items, a backup is created that stores your previous registry settings. Backups are stored on your computer so that you may revert back to a previous setting if desired. Backups are organized by date, and you can filter them by ascending or descending order.

  • Remove: Once you have selected a date, the Remove feature will delete the saved backup log. Once you have removed the log, you cannot revert back to a previous setting.
  • Restore: The Restore feature will revert your computers registry to a previously desired state. To use the Restore feature simply select the date you wish to revert your settings to, then click the Restore button.
