Karen's Registry Pruner

Complex applications usually write their own items in registry entries. However, removal of these programs doesn’t always delete associated registry entries, which can be the cause of particular errors on the long run. On the bright side of things, specialized tools like Karen's Registry Pruner can clear these invalid and orphaned registry entries.

Clear description to help you understand the process

Once setup is over, you get the chance to quickly check out the application’s set of features. The program doesn’t necessarily have to be launched with administrator privileges, but it can be a solution if you consider it’s not capable of properly detecting some items.
Most of the operation is automated, but you do have to pay attention to what entries you’re about to remove. The initial tab displays general info on the operation, which makes it quite easy even for inexperienced individuals to understand how to deal with registry entries. The application can handle two situations, namely shared, and add/remove registry entries.

Have orphaned and invalid registry entries removed

Both segments are displayed in individual tabs, but structured in the same manner. The status bar shows the number of detected items, and you can manually go through lists to check or uncheck items there. Additionally, you can choose to restore use counts of entries with zero count, and show program contents.
Registry entries in the add/remove section can give you quite an important insight on what programs make changes and add custom entries. Whereas the shared DLLs section mostly refers to entries which have no purpose anymore, as a result of improper or faulty program removal. The application warns you when it’s possible to cause future errors when selecting particular items for removal.
