What Browser Cleaner removes:
Cookies - Small files that websites store on your computer to track your activity
Download History - A record of every file you've downloaded (doesn't delete actual files)
Form History - Saved form data like addresses and search terms
Browse History - A complete record of websites you've visited
Cache - Temporary copies of web pages, images, and other content
Supported browsers:
Google Chrome
Mozilla Firefox
Microsoft Edge
Adobe Flash (legacy support)
The Browser Cleaner interface allows you to select specific browsers and specific types of data to remove. You can clean one browser or all browsers at once, giving you complete control over what gets deleted. This selective approach ensures you don't lose important saved passwords or bookmarks while still benefiting from improved privacy and performance.
In the example shown, Firefox has 5,575 traces found that can be cleaned. Regular browser cleaning is essential for maintaining fast browsing speeds and protecting your online privacy. It's recommended to perform this cleanup at least once a month, or more frequently if you browse extensively.
Step 4: Optimize Startup Programs
One of the most common complaints about Windows computers is slow startup time. The primary culprit is usually too many programs launching automatically when Windows starts. The StartUp Booster feature gives you complete control over which programs run at startup, dramatically reducing boot time.
How StartUp Booster works:

Over time, computers accumulate software that you no longer use. These unused programs waste disk space, can slow down your system, and may even run background processes that consume resources. The Uninstall Wizard provides a more thorough uninstallation process than Windows' built-in uninstaller.
Why use Uninstall Wizard instead of Windows uninstaller?
Standard Windows uninstallation often leaves behind:
Registry entries
Temporary files
Configuration files
Cached data
Shortcuts and references
The Uninstall Wizard performs a "deep uninstall" that removes not just the program itself, but all associated files, registry entries, and leftover data that standard uninstallation misses.
How to use Uninstall Wizard:
The interface displays a comprehensive list of all installed programs, showing:
Program name (e.g., "7-Zip (x64 edition)", "Ashampoo App")
File size
Installation date (when available)
Simply check the box next to any program you want to remove, and the yellow "Uninstall" button at the bottom will show how many programs are selected for removal. In this example, "7-Zip (x64 edition)" is selected for uninstallation.
Benefits of regular program cleanup:
Recover significant disk space (some programs can be several gigabytes)
Reduce system clutter
Eliminate potential security vulnerabilities from outdated software
Improve system performance by removing background processes
