Comparison of 176 Registry Cleaner Products: Other Error Detection
These tests were performed in October 2010
Other Error Detection Comparison
This test was performed on the 58 products that found at least some of the incorrect file references in the two previous tests. Using a freshly-installed copy of Windows 7, the following four errors were manually inserted into the registry:
- 1. Critical registry data relating to .bat file extension was removed, causing Windows to be unable to execute .bat files.
- 2. An incorrectly formatted entry was added under the HKEY_LOCAL_MACHINE\Software\Windows\CurrentVersion\Run key.
- 3. An empty key was added under the HKEY_LOCAL_MACHINE\Software\ key to simulate a left-over data from an uninstalled software.
- 4. An incomplete set of uninstallation data was added under HKEY_LOCAL_MACHINE\Software\Windows\CurrentVersion\Uninstall.
These registry errors did not contain any file references, valid or invalid.
