According to a well-kmown and respected Windows System Admin (Twitter: @SwiftOnSecurity) Registry Cleaners are at best useless and usually actually damaging.

Windows registry cleaners and optimizers look for banal, often completely fake, things in an immensely intricate system that people are scared of and don't understand. These programs use this position of trust to extort money and mislead users into believing they are required to fix specific problems or improve a flawed system.


In fact, registry cleaners will invariably find tens, sometimes hundreds or thousands of "issues" on a Windows system installed from a DVD an hour ago. You can test this yourself, it's a well-known way to demonstrate these programs have no idea what they are doing. ”Registry cleaners” will offer to damage a brand-new installation of Windows just to make it look like they are useful. Imagine being told your brand-new car with 50 miles on it needs the “headlight fluid” replaced. It’s the same scam.

I've never been helped by a Registry Cleaner on any version of Windows since 3.1. SwiftOnSecurity might be a bit over the top on this, but not by much.

  • "headlight fluid" -- that's hilarious.
