How to Clean Up 50+ GB of Junk Files in Windows 11 Without Third-Party Software

Running out of space on your Windows 11 drive? You may have gigabytes of temporary files, old Windows Update packages, crash reports, delivery files, and forgotten downloads taking up room. The good news: you do not need a third-party cleaner. Windows 11 already includes safe tools that can recover 10–50+ GB, depending on your update history and storage habits.

This guide combines the cleanup steps most tutorials mention with commonly missed areas such as hibernation, restore points, component-store cleanup, and large personal files. Follow our simple step-by-step guide, review each category before deleting it, and keep your important documents backed up.

Safety first: Do not delete random folders inside C:\Windows or AppData. Use the built-in tools below instead.

Check What Is Using Storage in Windows 11

Before deleting anything, find out where the space is going.

1. Press Windows + I to open Settings.
2. Go to System > Storage.
3. Open Temporary files and note the estimated size.
4. Check Installed apps, Other, Documents, and Downloads.

This quick scan prevents guesswork. If “Temporary files” is unusually large, continue with the cleanup steps below.

1. Delete Windows 11 Temporary Files

Windows stores temporary installation files, thumbnails, delivery files, and diagnostic data that can safely be removed.

1. Open Settings > System > Storage > Temporary files.
2. Let Windows finish scanning.
3. Select items such as Temporary files, Delivery Optimization Files, DirectX Shader Cache, Thumbnails, and Windows error reports.
4. Only select Downloads if you have checked that folder manually.
5. Click Remove files.

Do not panic if the scan takes several minutes. Large update caches can take time to calculate and remove.

2. Run Disk Cleanup as Administrator

The classic Disk Cleanup utility still finds system files that the modern Storage page may overlook.

1. Press the Windows key and search for Disk Cleanup.
2. Right-click it and choose Run as administrator.
3. Select your Windows drive, usually C:.
4. Click Clean up system files, then select the drive again.
5. Review categories such as Windows Update Cleanup, Previous Windows installation(s), Device driver packages, and Temporary Windows installation files.
6. Click OK > Delete Files.

Important: Deleting “Previous Windows installation(s)” removes your ability to roll back to an earlier Windows build. Keep it only if you recently upgraded and may need that rollback option.

3. Turn On Storage Sense Automatically

Storage Sense prevents junk files from building up again.

1. Go to Settings > System > Storage.
2. Turn on Storage Sense.
3. Open its settings and set the cleanup schedule.
4. Choose when to delete files in the Recycle Bin and Downloads folder.

Use a cautious schedule for Downloads. Automatically deleting files after a short period can remove installers or documents you still need.

4. Remove Old Restore Points

System Protection restore points can consume several gigabytes.

1. Search for Create a restore point and open it.
2. Select the Windows drive and click Configure.
3. Use Delete to remove existing restore points, or lower the maximum disk usage.
4. Click Apply, then OK.

Keep at least one recent restore point if you rely on System Restore for troubleshooting.

5. Disable Hibernation If You Never Use It

Windows creates hiberfil.sys, which can be several gigabytes. If you only use Sleep and never Hibernate or Fast Startup, you can remove it.

1. Right-click the Start button and open Terminal (Admin).
2. Run this command:

powercfg /hibernate off

To restore hibernation later, run:

powercfg /hibernate on

This is a legitimate Windows command, not a hack that damages your installation.

6. Clean the Windows Component Store

Old component versions can accumulate after many updates. Open Terminal (Admin) and run:

DISM /Online /Cleanup-Image /StartComponentCleanup

Wait for the process to reach 100%. Do not close the window or restart the PC during cleanup. DISM may recover several gigabytes, but the result depends on your update history.

7. Review Downloads, Large Files, and Recycle Bin

Built-in cleanup tools cannot decide which personal files matter. Open File Explorer and inspect Downloads, Videos, desktop folders, and old ISO or ZIP files. Sort by size, move important files to external storage, then empty the Recycle Bin.

Quick Fixes If Space Has Not Returned

• Restart Windows after major cleanup operations.
• Run Storage Sense again after Disk Cleanup finishes.
• Check Settings > System > Storage > Other for large application folders.
• Install pending Windows updates, restart, and run Disk Cleanup again.
• Never force-delete protected system folders to gain a few extra gigabytes.

Final Verdict

Windows 11 can handle a deep storage cleanup without third-party software. Start with Storage settings, run Disk Cleanup as administrator, remove unnecessary restore points, review personal files, and use DISM for older component data. With these steps, you get a cleaner drive, more free space, and no crash issues from questionable registry cleaners. Tested & 100% Working—and completely handled with tools already built into Windows.
