Microsoft PC Manager is a relatively new free tool from Microsoft that combines basic cleanup with system optimization. Here is how it compares:
Browser cleaning: PC Manager offers limited browser cleanup. RJL System Cleaner cleans all five major browsers with individual control over cache, cookies, history, sessions, download history, and form data.
Privacy cleaning: PC Manager does not clean Windows privacy traces like recent file lists, Run dialog history, search history, or jump lists. RJL System Cleaner does.
Application cleaning: PC Manager does not clean third-party application caches (Discord, Steam, Spotify, VS Code, etc.). RJL System Cleaner does.
Duplicate detection: PC Manager does not scan for duplicate files. RJL System Cleaner includes a built-in duplicate scanner that finds wasted space from identical file copies.
Transparency: PC Manager cleans what Microsoft decides is cleanable without showing individual files. RJL System Cleaner shows every file with safety ratings and lets you deselect individual items.
Telemetry: PC Manager is a Microsoft product and follows Microsoft's telemetry practices. RJL System Cleaner collects zero data.
Portability: PC Manager requires installation from the Microsoft Store. RJL System Cleaner is a portable .exe.
Where PC Manager wins: It is free, backed by Microsoft, includes a startup manager and storage management, and integrates with Windows Defender. If you want Microsoft's officially supported cleanup tool with no third-party trust required, PC Manager is a safe choice.
