Some Basic Tests
To see how well this tool worked, I ran two basic tests against it core features just to see what would happen out of the box.
The first test took advantage of Zappit's tweaking feature--startup manager. I measured my computer's startup time from the moment I entered my login credential to the point Windows Vista sidebar showed up; it took 1:22 (min:sec).
I then opened Zappit and selected the startup manager. Zappit allows you to manage current user/all user start menu and registry auto-starts.
From the start menu, I removed OneNote 2007 Screen Clipper and Launcher, as well as the Apache web services. From the registry, I removed the Sidebar, Google Update, Google Toolbar Notifier (SWG), and CDLOADER. Google quick searc box, HP usage tracking, HP software update, SUN Java UpdateSched, Groove Monitor.
I shutdown, and repeated the measurements. Now it takes 40 seconds--a 67% improvement in startup!
Warning: When in doubt about what you are removing, check with someone more technically adept, or simply do not remove what you aren't sure about. If you end up deleting a registry auto-start item which later on results in a program no longer working properly anymore, then you may have to restore your settings to a known good last restore point.
I did the cleaning test in 2 part: Safe mode, then Advanced mode.
Before running the cleaning test, I measured the current available space on the laptop I was using. It had 18.5 GB of free disc space.
After running the safe mode cleaning, I reclaimed 3.6 GB of free space in 6.5 minutes. My total free space now is 22.1 GB. I then started to check out the advanced mode. I ran it using the default settings; Zappit allowed me to reclaim another 1.3 GB, in 4 minutes.
This cleaning feature that got me back 4.9 GB of previously wasted space!
