Is a third party cleanup app worth it on Windows 11?

My C drive keeps filling up and the PC feels slower than when I bought it. Friend swears by some cleaner app, but I've also heard they do more harm than good. Is the built in Disk Cleanup / Storage Sense enough, or is there something better?

Mostly no. Windows 11 already has what they do: Settings > System > Storage > Storage Sense will clear temp files and the recycle bin on a schedule, and Disk Cleanup with 'Clean up system files' gets rid of old update leftovers, which is usually the big one. The registry cleaning bit these apps push does nothing you'd ever notice and can break things. Several of them also nag you to upgrade and install extra stuff alongside.
