These tests were performed in October 2010
Software Left-Over Data Detection Comparison
This test was performed on the 13 products which detected at least one of the test errors in the previous test. On a freshly-installed copy of Windows 7, we installed the following software:
- ACDSee Photo Manager 12
- Adobe Acrobat Reader 9
- AIM 7.3
- BitComet 1.23
- Camfrog Video Chat 5.5
- GoldWave 5.55
- iTunes (with QuickTime)
- Nokia Ovi Suite 188.8.131.52
- Open Office 3.2.1
- Quick Media Converter 4.0
- Spyware Doctor (with AntiVirus)
- VideoSpirit Pro 1.40
- VirtualDJ 6.1.2
- Winamp 5.581
- WinZip 14.5
All the software was installed using the default settings, meaning all the add-ons and browser toolbars that were selected by default were also installed.
The time it took for the freshly installed Windows 7 to fully start was 1 minute and 8 seconds. After the above software was installed, the startup time was 2 minutes and 21 seconds.
Next, the installation directories of all the installed software were deleted in order to simulate a very poor uninstaller that would leave a great deal of data behind. This action caused most of the registry data added by the software to become invalid. After this, the startup time of the system was 1 minute and 46 seconds.
Next, the following products were run in order to clean the registry, and after the scan the system was restarted in order to see the effect of the registry clean to the system startup time. The system was restored to its original state prior to each test.
