What Free Optimizers Typically Don't Offer (Limitations)

Real-time Optimization: Free tools often lack real-time optimization, meaning they only fix issues when manually triggered, rather than automatically maintaining system health.
Advanced Defragmentation: Advanced defragmentation tools that optimize files on a deeper level are typically reserved for paid versions, with free tools offering only basic disk optimization.
Driver Updates: Most free optimizers don't include features for updating drivers, which can be crucial for system stability and performance. You may need separate tools for this.
Deep System Analysis and Repair: While free tools can handle basic cleanups, they often lack in-depth system repair features like fixing corrupted system files or resolving complex performance issues.
Dedicated Customer Support: Free tools usually don’t provide customer support, so if you encounter issues, you're left to troubleshoot on your own through online forums or guides.
