PrivaZer, but you'll have to review before cleaning if you tic more cleaning options, if you use it by default it's ok, but remember that it's not the quantity of erased files which make a good cleaner, it's the efficiency.
@Practical Response, agree using windows cleanup tool never let you down.
For those want to gain more space Tips for Windows 10 users (never tried on W11, but maybe it's the same) : AT YOUR OWN RISK!!!!
1- Old bug, open control panel>Administrative tools>task scheduler>scroll down to windows then management and provisioning, deactivate Cellular and Logon tasks in the right pane, after go to C:\Windows\System32\config\systemprofile\AppData\Local and delete alls *.tmp (useless).
2- After each Patch Thuesday go to C:\Windows\servicing\LCU and delete the folder inside (Never had any issue).
3- Same as 2, go to C:\Windows\SoftwareDistribution\Download and delete the folder inside (same

).(WiseDiskCleaner do that too).
