If your Windows PC is running sluggishly or suffering from storage issues, temporary files may be part of the problem. Windows accumulates a surprising amount of temporary files over time through everyday use, software installations, browsing, and updates. While Windows provides built-in tools, advanced users often require more control and thoroughness. This guide covers both basic and advanced techniques for cleaning up Windows temporary files, with actionable advice for Windows 10 and 11 users.
Why Do Temporary Files Matter?
Temporary files are generated by Windows and third-party programs for short-term use, such as installation leftovers, browser caches, and system update backups. Over time, these files can:
– Consume significant disk space
– Slow down system performance
– Interfere with application updates and installations
– Cause privacy concerns if sensitive data is stored

How Can I Use Windows Built-In Tools?
1. Using Storage Sense (Windows 10 & 11)
– Click Start, then go to Settings > System > Storage.
– Toggle on Storage Sense for automatic cleanup.
– Click Configure Storage Sense or run it now to set schedules and choose what gets deleted.
2. Manual Cleanup via Disk Cleanup
– Press the Windows key, type Disk Cleanup, and select it.
– Choose the drive you want to clean (usually C:).
– Disk Cleanup calculates cleanup space; check boxes next to temporary files, Downloads, Recycle Bin, and previous Windows installations if desired.
– Click OK, then Delete Files to confirm.
3. Clear Browser Caches
– Open your browser settings (e.g., Chrome: Settings > Privacy and security > Clear browsing data).
– Select cached images and files, cookies, and more as needed.
Tip: Run these processes regularly, especially after large Windows updates.
Section 2: Advanced Temporary File Cleanup Techniques
How Can Advanced Users Remove Stubborn or Hidden Temp Files?
1. Manual Deletion from Temp Folders
– Press Windows + R, type %temp%, and press Enter. This opens the main Temp folder for your user profile.
– Select all files (Ctrl + A) and delete.
– Repeat with Windows + R, type temp, and press Enter. Delete all contents (Windows may require administrator approval).
2. Clean Up System-Wide Temp Files with Elevated Privileges
– Open Command Prompt as Administrator (right-click Start, select Windows Terminal (Admin) or Command Prompt (Admin)).
– Type the following and press Enter:
del /q/f/s %TEMP%\*
– For system temp, type:
del /q/f/s C:\Windows\Temp\*
Warning: Closing all apps before doing this is recommended to avoid deleting files in use.
3. Remove Windows Update Leftovers
– Open Settings > System > Storage > Temporary files.
– Check Windows Update Cleanup and Delivery Optimization Files.
– Click Remove files.
For advanced command-line users:
– Open Command Prompt as Administrator.
