Review of the Top Registry Cleaner Software – Free & Paid Registry Cleaners

We are presenting here, a review of top Registry Cleaners in the category of both best free and best professional versions. The purpose of this review of registry cleaner is to give the readers a well-rounded analysis of the best choice in the market.

1.Testing Environment

All the products mentioned were tested in a Windows environment with following hardware specs:

  • Windows 7
  • RAM: 1 GB
  • Processor: 1.8 GHz
  • Core 2 Duo
  • Hard Drive Capacity in
  • Bootable drive: 43 GB free of 73 GB

The system used for testing had a Windows installation that was about 4 months old. The PC suffered from unusually slow processing speed and an overly heated processor. The startup was slow and overall performance of the system was below par.

2.Parameters of Testing

ALL products have been tested individually by our team. Their analysis was then combined with the reviews and tests conducted by other forums over the web. For clarification of criteria of testing, detail about the parameters listed as column headings is given below:

Size on Disk is the size of software folder in the Program Files and plus other system files.

Installation adds files to the Registry itself refers to files that are added in the registry by the product and not by the Windows (because that would be true for every program).

“Uninstallation leaves files behind” analyzes whether the product uninstalled itself completely or did it leave files behind in the registry and other areas.

Types of Scanned Files: Registry Cleaners scan and fix a number of files. The most important and useful of these file fixes are those detected in invalid DLL, Application paths, File associations and Uninstall entries. The performance of registry cleaner is evaluated on the basis of how many of these entries are found. A registry cleaner that claims junk files are errors, which is rare, will lose points in performance.

The analysis mentions but does not rank on the basis of time of scan. Although all products were tested on the same system but all registry cleaners do not look for the same kinds of files, so the time of scan varies by large margins. Some registry cleaners, mostly the free versions, simply inflate their number by reporting every little file as a candidate for cleanup.

As you can see in the Free registry cleaner review, the programs find huge number of files. When compared with the professional versions, the error count is usually low. We mentioned earlier in the article, Free vs Pro Registry Cleaners that free software likes to inflate its entries and adds every random file in the count to come at the top. With professional versions, this issue is not observed in most cases. Only the valid and important files are scanned therefore the error count is much lower.
