Temporary files in Windows can quickly accumulate, taking up valuable disk space and sometimes affecting your PC’s performance. Cleaning these files is a routine part of PC maintenance but, occasionally, you may run into issues where temporary files refuse to delete or cleanup doesn’t work as expected. This guide will walk you through 12 proven methods to troubleshoot and resolve problems with Windows temporary file cleanup, offering easy steps for beginners and detailed tips for advanced users.
What Are Windows Temporary Files and Why Do They Matter?
