Let WinOptimizer clean, optimize and protect your machine and enjoy a fast, lean and secure Windows PC with intact privacy, permanently! WinOptimizer puts a stop to this, fast, easy and effectively! It whips your PC back into shape and makes it feel like new again.

And then there's the constant privacy intrusion introduced with Windows 10 and 11, euphemistically dubbed 'telemetry'. Important settings are also either missing or hidden deep within the system. That's where Ashampoo WinOptimizer comes in! Because, over time, operating systems tend to slow down, become unstable and clutter up. Windows is great – but there's always room for improvement. The new Ashampoo WinOptimizer 25 comes with a double boost! Speed up and clean your PC in just a few clicks!
