How to Remove Temporary Files on Windows

Before You Clean

Temporary files can include active work and installer data. A locked-file check alone is not enough to decide a file is disposable.

Review and Clean Manually

1. Save work and close apps. Let Windows updates and installers finish before cleaning.

2. Open Settings > System > Storage > Temporary files. Review the available categories rather than selecting everything.

3. Keep Downloads and Recycle Bin out unless you have reviewed them. Remove only the temporary categories you approve.

4. For a particular application, use its own maintenance tool. Do not force-delete files from Temp while its installer or update is running.

5. Record actual free space after cleanup. Investigate an app that immediately recreates a large amount of temporary data.

Where Kudu Helps

Kudu scans user and system temporary targets. Keep Skip recent files configured and review the paths; it reduces risk but does not replace closing apps or reviewing your selection.

Open Clean up > System Cleaner and run Scan. Review the relevant category and expand its results to inspect the paths. Set exclusions for anything you need to keep, then check the full selected total before Clean. Results search filters the view; it does not erase selections elsewhere.

After cleaning, check the summary and Activity > Cleanup receipts for removed, skipped, or failed items. A receipt is an outcome record, not a backup. Recovery Centre restores supported settings, not deleted files. Compare actual disk free space and test the original symptom; cache removal alone is not a promise of better performance.
