Why does RJL System Cleaner not include a registry cleaner?

This is an intentional design decision, not a missing feature.

Registry cleaners have been controversial for over a decade. The Windows registry contains tens of thousands of entries, and so-called "registry errors" found by cleaning tools are almost always harmless orphaned entries that have zero impact on your system performance or stability.

The risks of registry cleaning are real:

• Deleting the wrong registry key can prevent applications from launching
• Aggressive registry cleaning has been known to cause Blue Screens of Death
• Microsoft itself has stated that registry cleaners are unnecessary and can cause problems
• The performance benefit of removing unused registry entries is essentially zero on modern hardware

Even CCleaner, which prominently features a registry cleaner, has faced criticism for years over registry cleaning causing system instability.

RJL System Cleaner focuses on what actually helps: removing junk files that waste disk space and cleaning up privacy traces. These provide real, measurable benefits without any risk to your system.
