Benchmark of Top Ten Windows Registry Cleaners

Introduction

In recent years, Macecraft Software has published a total of five registry cleaner product comparison studies which have attempted to answer questions about the quality of different registry cleaning products as well as what kind of effects they can have on your system.

History

The first study of this kind dates back to 2009 and was entitled “Registry Cleaner Review and Performance Comparison Study“: https://www.macecraft.com/registry_cleaner_comparison/

A follow-up to this research was released later in the same year. It was Macecraft Software’s “In-Depth Review of 31 The Most Popular Registry Cleaner Products” study: https://www.macecraft.com/registry_cleaner_comparison2/

In 2010, a Comparison of 176 Registry Cleaner Products study was published: https://www.macecraft.com/registry_cleaner_comparison2010/

In September of 2013 we did a study from a different point of view: this time it focused on whether or not running a registry cleaner software results in changes to system performance. To measure this, we used globally recognized benchmark scoring software to measure the performance of the test system before and after using a registry cleaner. That study was entitled the Registry Cleaner Benchmark Study: https://www.macecraft.com/registry-cleaner-benchmark-study/

The most recent study was published in March of 2015 and it further continued to discuss actual, measurable effects that different products claiming to optimize Windows have on a computer’s performance. This study was entitled the Benchmark Report of 133 Windows Optimization Software Products: https://www.macecraft.com/windows-optimization-software-benchmark-report/

Latest Benchmark of Top Ten Windows Registry Cleaners

These tests were done in October, 2016. The technical details and complete tests results have been documented on our blog: https://www.macecraft.com/benchmark-top-ten-windows-registry-cleaners/

This current case study aims to continue the tradition that Macecraft Software has established while releasing similar product comparison test reports alongside every recent major product release. The latest benchmark test report currently covers the following tests completed in October 2016:

Test 1: Number of errors found

Test 2: Windows startup time (measured with a stopwatch)

Test 3: Windows startup time (measured with software)

Now that jv16 PowerTools 2017 has been released, this is a practice that we wish to expand over a follow-up, extended study that we will later do in January of 2017. If you wish to learn more about the release of jv16 PowerTools 2017, you can find the complete release related information here: http://www.macecraft.com/jv16-powertools-2017-released/

All of the test results are accompanied by screenshots and video recordings which have been saved during various testing phases in order to address some of the most common test result credibility concerns for this type of studies.

This case study is open to discussion and public review on our forum, in this thread.

We would strongly appreciate if you could join the discussion, let us know what you think about the test results and recommend us new test ideas that we should cover in future similar studies.

Suggest that you also test "False Positives", for each of the cleaners. Results seem to indicate that JV16 is the most aggressive, but is it also most likely to remove something that the system requires, resulting in problems?

Regseeker appears to have not been included.

The only other registry cleaner I use.

This is a very good point! We normally also test for false positives but didn't have the time to do that testing this time. We will include that in our next test, which ought to released later in this month.

We only included products that came up with Google as the ten most popular products. We will include more products, including RegSeeker to the next test. Thanks for the tip!

I've used JV16 for many years (guess from Win98) and never had a crash or bsod after running the registry cleaner, which I always set at the lowest security level before the warning red cross. At my last cleaning a few days ago JV16 revealed "only" 183 errors, while Wise Care found 827 errors, but with only 32 marked as safe to delete. Again: what' s the benefit of finding so many errors if you're warned that it's not safe to delete them ?

Thank you Macecraft for this registry cleaner, for me it's THE reference !
