Why clean your system?

Over time Windows collects junk:

• Temporary files left behind by programs and updates
• Invalid registry entries pointing to removed software
• Broken desktop and Start Menu shortcuts
• Browser caches, cookies, and browsing history
• Hotfix uninstall files that are never used

All of this quietly eats disk space and can slow your computer down. A regular clean keeps your system tidy and fast.
