Registry First Aid can solve Windows crashing, software freezing, and slow loading issues caused by incorrect registry entries created by problematic software installations and un-installations.

Often times, un-installations don't fully clear out your registry, leaving behind invalid file/folder references that can cause software to lock up or load slower. Registry First Aid scans your registry for orphaned file/folder references, and even finds files or folders on your drives that may have been moved from their initial locations. It then corrects your registry entries to match the located files or folders.
Lingering registry entries from deleted applications can also cause performance issues, but Registry First Aid quickly identifies these invalid entries and removes them for you. Your Windows registry will permanently be clean and correct, which maximizes the speed of your computer and reduces software crashes.
Registry First Aid comes complete with a range of features that make cleanup tasks easy. You can select drives and paths to search registry referenced files/folders and choose found matches to make corrections to invalid registry entries. You can even delete incorrect registry references to previously un-installed files or folders.
Finally, Registry First Aid allows you to create undo files in RegEdit4 format, so you always have the option to restore your Windows registry to the original state if necessary. Overall, Registry First Aid helps your registry remain clean and healthy, resulting in a faster and more stable computer.
