There are several registry categories that you can select to scan.
We recommend that you become familiar with the registry to some degree so as to best understand how to manage it using PC Health Advisor.
To view the Registry settings:
- From the main window, click the Settings tab, and click the Registry Settings button.
The table below describes the types of registry items based on categories.
Invalid Entry Description
The ActiveX section of the Windows registry can contain invalid entries that can cause application failure, system crashes, or errors when opening documents.
The Uninstall Entries section of the Windows registry can contain invalid entries or point to one or more missing entries. Typically this is due to incorrect installing or uninstalling of applications.
The Fonts section of the Windows registry can contain one or more missing font files that can cause errors in applications (for example, Word processing applications).
The Shared DLLs section of the Windows registry can contain invalid entries that cause application failure due to DLL conflict.
The Application Paths section of the Windows registry can contain invalid disk directories that can cause application failure.
The Help section of the Windows registry can point to invalid help files that can cause application help files to open incorrectly.
The Run section of the Windows registry can contain missing program entries that can be caused by incorrect installing or uninstalling of an application.
File Path Reference
Some registry items can be associated with non-existing files and folders such as when temporary files are used for storage. These entries may still be valid and required for use. Only remove entries that you know are invalid.
Program shortcuts with a ".lnk" extension, may no longer be linked to an application.
The program checks file extensions to verify if the associated shell open command is valid. If a file type is associated with a program that does not exist you will not be able to open the file. For example, you install an application that sets itself to be associated with a file type, you then uninstall this program and the registry is not cleaned up properly. The result is that the file type association is no longer functioning.
Selecting Registry Settings
You can choose which registry items you want to include in your registry scan.
