What is Microsoft PC Manager?

Microsoft PC Manager is a computer maintenance and acceleration program developed by Microsoft for Windows 10 and 11. This free program manages various tasks that slow down the computer, including deleting junk files, clearing memory, managing system applications, and performing a system health check—all in one program.

This app started by a Microsoft team in China under the name 电脑管家 (Computer Cleaner) before being adapted into an international version and released for free through the Microsoft Store. The idea was that Microsoft wanted to have its own official, secure system maintenance tool, without relying on third-party cleaning tools, some of which secretly contain advertisements. Those familiar with... CCleaner Pro Those who came before will find it easy to adapt, as their main function is the same: to clean up junk files and clear up the computer.

The heart of the feature is the Boost button on the home screen, which clears RAM with a single click. By temporarily closing unnecessary background processes, it instantly restores sluggishness caused by many apps running in the background without requiring a restart. The Health Check feature scans the device and reports problems such as accumulated junk files, too many apps automatically opening at boot, or settings that need adjusting. You can then fix all of these issues in one go.

In terms of storage, there are tools to delete temporary files, cache files, and unnecessary system files. It also allows you to find the largest files consuming the most disk space to make it easier to decide whether to delete or move them. You can also see how much space each app is using and uninstall unused ones.

The program manager for managing automatically run items at startup helps resolve slow boot issues. It allows you to easily view a list of all processes and close unnecessary ones. The process manager displays all running processes, allowing you to directly close those consuming excessive resources.

In terms of security, it doesn't have its own antivirus engine but connects to the existing Windows Security, allowing for direct virus scans. It also prevents other apps from changing the default browser or homepage without permission, and includes a pop-up manager to reduce annoying advertisements.

Finally, there's the Toolbox, which includes small tools like screen capturing, extracting text from images, and recording audio. No separate software installation is required, making it ideal for general users who want their computer to perform at its best without needing in-depth knowledge, as everything is integrated into a single window. Being from Microsoft itself, it doesn't conflict with the system and contains no hidden advertisements.

Things to know about this program.

Microsoft PC Manager doesn't introduce all new tools from scratch, but rather consolidates existing system administration tools that were previously scattered across multiple menus into a single, easily accessible window. Another important point is that Smart Boost mode automatically activates when the system's RAM is full or when temporary files exceed 1 GB, eliminating the need to manually activate it every time.
