Error Nuker Review

Features
Automatic Scan - Error Nuker's default scan, covers all types of errors
Custom Scans - based on type of error (ie. shared DLLs, invalid startup entries, missing fonts)
Manual Cleanup - after the scan a detailed list of errors found is displayed, broken down by type; fix individual entries, all entries, or just entries of a particular type
Backup and Undo - not the end all of safety features (as Error Nuker's developers are the first to admit - read below), this is still an integral feature to have; backs up your registries before you scan so that you can restore it should you accidentally delete a file you need
Scheduler - program Error Nuker to perform a scan every time your computer starts up or at regular, user-specified intervals

Ease of Use
Truly a breeze - just backup your registry, perform a scan, and delete all invalid entries
The interface is clean and straightforward

System Requirements
Windows (98, Me, 2000 or XP)

Customer Support
Support is limited to email query tickets
A decent tutorial with screenshots is provided but that's all there is
And their FAQ is minimal

Safety
Takes extreme care with your registry - vowing never to delete an entry if doing so could harm your system
Uses their own Registry Repair Algorithm (WRRA) to ensure no Windows Registry keys are removed
Claims to have reduced the number of "false positives" to zero
Notes that products with only "Backup and Restore" features fail in that the wrong deleted entry could prevent the computer from booting entirely, thereby preventing any opportunity to backup or restore

Free Scan
Yes & a free 30-day trial key

Refund Policy
None listed (probably because they already give you a 30-day trial)
