It must be noted that it is considerably challenging to accurately measure computer’s startup time manually by using a stopwatch, as what was done in the previous test.
Therefore, the test was repeated using a software to measure the computer’s startup speed. The new jv16 PowerTools features a tool called the Startup Timer, which, when enabled, measures accurately the time it takes Windows to fully start.
Furthermore, it is safe to assume that one can see the results of running a registry cleaner more clearly the more there is something to clean in computer. That is, using a registry cleaner in a system that has very little software and nothing to clean is most likely unneeded.
This is why the Windows 10 test environment of the previous test was changed in a way more software were installed to the system.
Examples of software installed: Adobe AIR, Adobe Shockwave Player, AIM 7, BitTorrent Sync, Classic Shell, CutePDF Writer, eMule, Everything, FastStone Image Viewer, FileZilla Client, Foobar2000, Greenshot, ImgBurn, InfraRecorder, Java, Launchy, MediaMonkey, Microsoft Silverlight, Mozilla Firefox, Opera, Putty, Python, qBitTorrent, Steam, SumatraPDF, TeamViewer 11, TeraCopy, Trillian, VNC Server, Winamp, WinDirStat, WinMerge, WinRar, WinSCP and XnView.
To establish a baseline, the system was restarted multiple times and its startup time was recorded by jv16 PowerTools’ Startup Timer. The last four startup times were: 139, 110, 151 and 163 seconds, resulting a median startup time of 145 seconds. As expected, installing more software to a Windows system caused it to work slower.
Next, the system was cleaned by each registry cleaner product, the system was restarted one time to apply the changes and then restarted four more times and the startup time was recorded using jv16 PowerTools’ Startup Timer feature. After each software was used, the system was restored to its original state using the virtual machine’s snapshot restore feature.
Cleaning the Windows 10 system with registry cleaners had the following impact on the system’s startup time:
