01.What are Temporary Files and why do they weigh on the PC?
Every time you install an app, browse the internet, or unzip a file, Windows 11 creates temporary copies in these folders. They should disappear on their own, but the system often 'forgets' gigabytes of data there.
Accumulation of temporary files causes slowness in quick disk access (SSD/HDD), can corrupt installation caches, and in extreme cases, prevent essential updates due to lack of space.
Storage Sense
The native Windows 11 feature is a good start. Go to Settings > System > Storage and turn on the Sensor. It cleans the recycle bin and the downloads folder after a certain period.
Don't do it Manually.

02.Automation via Task Scheduler
For more aggressive cleaning, you can create a task that runs when Windows starts:
Executable Command: cleanmgr.exe /sagerun:1
This triggers the classic Disk Cleanup with your pre-defined settings, without you needing to open any window. However, it still ignores browser caches and heavy logs.
