Abyssal Registry Cleaner

Abyssal Registry Cleaner facilitates a user-friendly interface for scanning the Windows registry for invalid entries to repair them. It automatically creates backups and gives you the possibility to restore settings to a previous and stable OS state, in case you encounter any issues.

The only requirement of the tool is .NET Framework. Regarding the design, the program is packed in a clean and intuitive GUI, which consists of a single window split into multiple frames, where you can check out the overview, run scans, configure settings, and restore backups.

The overview area shows the date and time of the last registry scan, along with the number of found and fixed errors.

As far as error types are concerned, Abyssal Registry Cleaner verifies the registry for invalid file associations, DLL file references, application paths, ActiveX, OLE and COM objects, DirectShow filters and codecs, system files, references to temporary files, shortcuts, and others.

On scan completion, you can handpick the errors to fix while excluding the rest, as well as ignore any items from the current and future scans. As mentioned earlier, backups are automatically performed, and you can restore them from the last tab.

When it comes to program preferences, you can opt for another UI language, hide registry details during the scan job, and remove any items from the ignore list.

It used low CPU and RAM during scan jobs, and didn't hang, crash or show error messages. However, we ran its scanner alongside another powerful registry cleaner, and Abyssal Registry Cleaner missed a wide range of registry issues.

To sum it up, this tool seems to have the necessary and suffice options for verifying and fixing registry issues. But it delivered less than desirable results in our tests.
