Clear temporary system folder

Overview​

About this script

This script improves your privacy on Windows.

These changes use Windows system commands to update your settings.

This script eliminates the contents of the %SYSTEMROOT%\Temp\ directory, also known as the Windows Temp directory 1. This directory is located within the Windows system folder %SystemDrive%\Windows\Temp\ 1 2. It is used by the system and system-level processes to store temporary files, including those generated by the operating system and other system-level software.

This folder, protected by specific access control lists (ACL) 3 4, is accessible only to system-level accounts 2.

Known for being utilized by malware, cleaning this directory is recommended for maintaining system security 2 5. Moreover, it's used for forensics to analyze user behavior 6, thus raising privacy concerns.

Microsoft underscores the importance of cleaning this folder to free up disk space 7, resolve system application issues 1 8 9, and counteract malware 2. Some system applications may populate this folder, taking up considerable disk space 7 9 10.

This script only deletes the contents of the %SYSTEMROOT%\Temp\ directory, not the directory itself, to maintain system integrity, security, and privacy, avoiding potential issues caused by unintentional directory deletion without proper ACL. Deleting the directory itself might disrupt certain applications, such as dism 11, and application installers 12, while also removing the special ACL that secures the folder.

This script uses Batch (batchfile) scripting language.

Safe for General Use

This script is recommended for all users. It helps to improve privacy without affecting stability.
