The second step shows the progress of scanning. Registry Cleaner checks each section of the Registry in detail leaving no loopholes in the process. The Registry has been broadly divided in 14 areas briefly explained below. You can anytime abort the scan operation by clicking on the “Stop Scan” button in the lower right corner.
ActiveX and COM
An ActiveX and COM is a program that comprises of set of rules that tells as to how programs should share information. ActiveX and COM components install on system while browsing internet or installing any application. Invalid ActiveX and COM components in Registry increase the size of the Registry and may also contribute in the malfunctioning of many programs on system, in system crashes, application failures and loss of information.
Application Paths are system-wide setting Registry keys in HKEY_LOCAL_MACHINE\Software\Microsoft\Windows\Current Version. Each app path key refers to a file name and a file path of an application installed on system. To launch an application, you can directly type the app in Start=>Run instead of typing the complete file path.
Sometimes applications are uninstalled or moved from the original physical locations. In such scenario, the app paths become invalid referring to wrong file paths and application file names and may cause problems while executing other applications. Registry Cleaner identifies such invalid app paths and removes them from Registry.
Many programs installed on a computer have different file extensions associated to these programs. Invalid File Type entries occur when some file extensions refer to programs that no longer exist on a computer. Registry Cleaner looks for such file types and remove them from the registry.
Registry contains information regarding the installed font types. The key which refers to a specific font type contain its filename and file path. In case, the paths are edited or names are changed, invalid entries are created. These can cause problems and therefore, these invalid font entries should be removed from the Registry.
Help files create Registry entries referring to the file paths and file names. The moment help files are removed or moved from their original location, these entries become invalid. Registry Cleaner identifies such invalid Help file references existing in Registry and helps to remove them.
Registry also stores entries of files and documents accessed recently. The entries become invalid when the files are moved from the original physical location or deleted from the system. Registry Cleaner scans and finds out such orphaned entries and cleans them from Registry.
Registry entries include paths of shared files and program libraries (dlls) that are used by various programs. These entries become invalid when they point to the shared files that are moved from the original locations or have been deleted. Registry Cleaner intelligently scans and identifies such invalid Registry entries.
Program shortcuts are also stored in Registry. Some shortcuts refer to programs that do not exist on system. Such entries that refer to invalid shortcuts increase the size of the Registry. Registry Cleaner also targets such entries and reports the user of the same.
When a software application is installed on system, it also creates few Registry entries storing all the information regarding its configurations and settings. But when these software applications are uninstalled from system, the associated Registry entries are not removed thereby cluttering the Registry. It is essential to remove such invalid entries.
Registry stores information related to all the sound files on system. Some entries in Registry may point to the sound files which do not exist on system or which have been relocated from the original physical locations. Registry Cleaner helps to get rid of invalid sound entries.
Programs in Start Menu are read from Registry before they are launched at startup. The Registry entries that refer to startup programs that are moved from the original location or are no longer on the system will become invalid. Registry Cleaner contributes in identifying all such invalid entries and cleans them from the Registry.
Some programs are scheduled to run at windows startup. Registry maintains the entries of such programs. In many cases, the entries become invalid pointing to programs that are no longer on system or are moved from the original physical locations. Registry Cleaner finds the invalid entries that bloat the Registry and reports the user.
Deep Scan is a more comprehensive mode of scanning and thus takes longer. It scans everything in HKEY_LOCAL_MACHINE Registry hive and identifies more erroneous entries pointing to invalid data references in comparison to any other type of scanning.
Current User basically refers to the profile of the user contained in HKEY_CURRENT_USER currently logged on to the computer system. The user profile includes environment variables, personal program group settings, desktop settings, network connection settings, printer settings and application preference settings. Registry Cleaner will identify erroneous entries in HKEY_CURRENT_USER subtree and inform the user of the same.
The results after scanning are shown in the third step. The number of errors detected under each category/area is shown separately, the details of which can be viewed by clicking on the link “Details” or clicking on the category headings. You may click on the “Fix All Errors” button to remove all the errors detected. To go back to the Welcome screen and rescan Registry for errors, click on “Cancel” button.
When you click on the category headings or click on the link “Details”, in either of the cases, the details of the errors detected can be viewed in a separate window. Corresponding to each erroneous Registry entry, a checkbox is positioned. You may check mark the entries to be deleted or select the option “Select All” to select all entries in one go. After you finish selecting, you may then click on the “OK” button to continue.
The selected errors in the previous step are cleaned from the Registry and simultaneously an automatic backup is also taken as a precaution. In case, the changes are not satisfactory, the backups can be restored using the options under the “Undo Changes” tab.
The process of cleaning can be stopped at any point of time by clicking on the “Stop Cleaning” button.
Note: Although changes can be undone, one must be very careful before deleting Registry entries from the system.
Registry Cleanup Summary
In the last step, the cleanup summary is put forth showing the details viz, Scan Results, Errors Repaired and Errors Remaining to be repaired.
You may click on the “Scan Again” button to rescan the Registry for errors and the “Finish” button takes you back to the Welcome screen where again you may choose to rescan the Registry.
