Buying advice

Consider your primary need: general cleanup (CCleaner), gaming (Razer Cortex), Mac (CleanMyMac), or free solution (Advanced SystemCare). Most tools offer trials; test before purchase. Avoid aggressive registry cleaners on solid-state drives (SSDs) as they may not benefit significantly.
