Microsoft PC Managaer

If you're looking for a PC manager for Windows 10 that is completely free and focuses on monitoring and optimizing performance, Essential PC Manager is a viable option.

Since you mentioned that basic cleanup hasn't made much difference, your slowdown may be coming from something other than just junk files. Essential PC Manager could help you identify whether specific applications are consuming excessive system resources. If you find that no single app is dominating your CPU or RAM, then your issue is likely disk-related (storage clutter, fragmented HDD, or system file corruption), which Essential PC Manager cannot address.

For a complete PC manager for Windows 10 that handles both resource monitoring and disk cleanup, consider pairing Essential PC Manager with a dedicated disk cleaner.

Tips:

View and terminate resource-intensive apps – Identify and kill the top 20 RAM-consuming applications

View and kill top 20 CPU-consuming apps – Identify processes placing the highest demand on your CPU

Monitor RAM and CPU usage by app – Real-time data for each running application

PC information display – View processor specifications, installed memory, storage capacity, and more

Something about the PC manager for Windows 10. A free and open-source application designed specifically for cleaning and optimizing Windows systems.

Pros:

• Simple and powerful interface
• Clears system caches and deletes temporary files
• Performs system health checks
• Open-source so you can audit exactly what it does
• Lightweight with minimal system impact

Note: The project had its last commit over 11 years ago according to OpenHub data. While this raises some concerns about Windows 10/11 compatibility, community users report it still functions for basic cleanup tasks.

Given that basic cleanup hasn't helped much, your slowdown likely comes from one of these deeper issues:

• Startup programs accumulating → Use Task Manager > Startup to disable everything non-essential
• Corrupted system files → Run sfc /scannow (this alone fixes many mysterious slowdowns)
• Windows Update leftovers → Use Disk Cleanup with "Clean up system files" (often recovers 5-30 GB)
• Background telemetry/services → Use Ashampoo's AntiSpy or Win10BloatRemover to disable resource-heavy Windows services

If you prefer open-source: Use Win10BloatRemover combined with built-in Disk Cleanup—this gives you control without a traditional "PC manager for Windows 10" interface .
