Clear out junk files and repair common Windows errorsFree Scan →Fix the driver behind crashes, sound loss and screen glitchesFind Drivers →Repair Windows errors before they cause bigger problemsFix Now →For most Windows 11 PCs, start with the free cleanup tools already built into Windows: Storage Sense or the Temporary files page in Settings. They can remove selected files and help reclaim storage; they are not proof that registry cleaning will make a slow computer faster. If cleanup does not help, check other possible causes such as startup apps, outdated software, malware, or older hardware.
What a free cleaner can—and cannot—do in Windows 11
“Cleaner” can mean several different things. A junk-file cleaner removes selected temporary, browser, or application files. Storage cleanup may help when the system drive is nearly full: Microsoft notes that low disk space can reduce system performance. A startup manager changes which apps launch with Windows. A registry cleaner changes registry entries, but a vendor’s feature description alone does not establish that this improves performance.

These are separate tasks, not interchangeable fixes. Microsoft lists storage limits, startup apps, outdated software, malware, and older hardware among possible reasons a PC may feel slow. Removing files will not resolve every cause, and software settings may not substantially improve an older machine. See Microsoft’s Windows performance guidance for its broader troubleshooting steps.
Use Windows 11’s built-in junk-file cleanup first
Automate cleanup with Storage Sense
- Open Settings > System > Storage > Storage Sense.
- Turn on Storage Sense and choose the schedule and cleanup behavior that suit you.
- Review the Downloads and cloud-content settings before relying on automatic cleanup. Storage Sense works on the system drive; by default, it does not manage Downloads or cloud content unless you configure it.
Microsoft explains the scope and settings in Manage drive space with Storage Sense. Check the selections carefully so that an automated cleanup matches what you intend to keep.

Choose files manually

Which free Windows 11 cleaner should you choose?
Built-in tools are the straightforward choice if your goal is reclaiming storage without installing another cleaner. For a separate app, Microsoft PC Manager is Microsoft’s own option for cleanup and startup management, and its product page lists Windows 11 compatibility. The other options below are third-party products; their listed functions and free-versus-paid tiers come from their vendors, not independent performance tests.

How to choose without over-cleaning
- If storage is the problem: Start with Windows cleanup and review the categories before deleting anything. Add a third-party cleaner only if you need a specific feature it lists.
- If startup is the problem: Look for startup-management controls rather than assuming a junk-file or registry scan will help. Microsoft PC Manager is one first-party option that describes startup management.
- If you want browser or app cleanup: Check exactly which browsers and applications a product says it supports, and whether those functions are included in its free tier.
- If a tool offers registry cleaning: Treat it as an optional registry modification, not routine maintenance or a demonstrated speed fix. Do not approve changes simply because a scan labels entries as unnecessary.
- If privacy matters: Read the product’s own privacy or policy information. For CCleaner, its policy distinguishes local processing for certain cleaning-related data from service data collected by the company.
If Windows 11 is still slow after cleanup
Use cleanup as one diagnostic step, then investigate the other causes Microsoft identifies. Check which apps launch at startup, install available Windows and app updates, and scan for malware. If the PC is older, software cleanup may have limited effect. Microsoft’s performance tips provide steps for these broader checks.
