Using Command Prompt as a free clean up app for PC is a practical approach if you're comfortable with command-line operations and want to avoid other PC cleanup tools. While it doesn't replace dedicated cleanup programs, you can perform several cleanup tasks manually, which can help free up space and improve performance.

1. Delete Temporary Files
Temporary files can accumulate over time and take up significant space. You can delete them with the following commands:

del /q /f /s %TEMP%\*
rd /s /q %TEMP%

%TEMP% points to your temporary files folder.
This command deletes all files in the temp folder and then removes the folder itself.

net stop wuauserv
del /q /f /s C:\Windows\SoftwareDistribution\Download\*
net start wuauserv

PowerShell -Command "Clear-RecycleBin -Force -Confirm:$false"
