Automated Windows temporary cache & prefetch cleaning utility
WinTempCleaner
WinTempCleaner is a lightweight Windows batch script and endpoint maintenance tool engineered to automate the removal of lingering temporary and cached files across critical operating system directories (%TEMP%, %WINDIR%\Temp, %USERPROFILE%\AppData\Local\Temp, and C:\WINDOWS\Prefetch). Developed alongside security research into malware staging tactics (detailed in the analysis article 'Why Attackers Like the Temp Folder'), WinTempCleaner enforces safe execution: preserving directory tree hierarchies, forcing read-only file removal, suppressing non-critical error noise, and providing real-time visual console feedback while preventing unauthorized background executions through interactive confirmations.

Problem
Windows default temp locations accumulate gigabytes of orphan caches and unmonitored staging artifacts that reduce storage, degrade system responsiveness, and create opportunistic staging grounds for persistence scripts.
Solution
A battle-tested Windows batch utility with interactive Y/n confirmation safeguards, recursive read-only file deletion, silent handle lock handling, and administrative permission elevation handling.
Outcome
A streamlined system utility and security research companion demonstrating Windows environment variable targeting, batch scripting automation, and disk hygiene maintenance.
