KauaRios/WinOptimizer ? reverse-engineered prompt

Build me a simple Windows optimizer app called WinOptimizer.

I want a clean desktop program that helps a user speed up and tidy up their PC with a few basic tools, like showing system info, cleaning temporary files, and offering a couple of safe optimization options. Keep it straightforward and easy to use, with a simple interface and clear buttons so someone non technical can understand what each action does.

Make it feel like a small Windows utility, not a complicated enterprise app. If you need to look up current Windows API or C++ docs online to do something properly, go ahead. Focus on getting a working first version that feels polished and practical.
