c. Select Keys
You can see all the invalid or orphan registry keys detected. Detailed
information is provided about each registry key (name, value, priority,
category).
The registry keys are grouped based on their location in the Windows Registry:
● Software Locations. Registry keys that contain information about the
path to applications installed on your computer.
The invalid keys are assigned a low priority, which means that you can delete
them without almost any risk.
● Custom Controls. Registry keys that contain information about the file
extensions registered on your computer. These registry keys are commonly
used to maintain file associations (to ensure that the correct program opens
when you open a file using Windows Explorer). For example, such a registry
key allows Windows to open a .doc file in Microsoft Word.
The invalid keys are assigned a low priority, which means that you can delete
them without almost any risk.
● Shared DLLs. Registry keys that contain information on the location of
shared DLLs (Dynamic Link Libraries). DLLs store functions that are used by
installed applications to perform certain tasks. They can be shared by
multiple applications to reduce memory and disk space requirements.
These registry keys become invalid when the DLL they point to is moved to
another location or completely removed (this usually happens when you
uninstall a program).
The invalid keys are assigned a medium priority, which means that deleting
them may negatively affect the system.
By default, all the keys are marked for deletion. You can choose to delete
individual invalid keys from a selected category.
