Manual Approach: With a manual approach, you have to take the time to scan for issues and then manually fix them. This can be complicated, time consuming, and involve considerable technical expertise.
PC Optimization Software Tool: With a dedicated PC optimization software tool, you simply download and run the program, and it will automatically scan for potential issues and repair any that it finds. This is much easier and faster than the manual approach, but may not offer as comprehensive an analysis or repair as more detailed, manual diagnostics would.
