How to Free Up Disk Space on Windows Without Software
A complete step-by-step guide to removing junk files and recovering storage on Windows 10 & 11 — without installing any tools.
Quick Summary
Main Goal
Free up disk space on Windows using built-in tools like Storage Sense, Disk Cleanup, and manual temporary file removal.
Core Issues
Junk files, cached data, update leftovers, and large hidden folders often consume gigabytes of storage.
Best Solutions
Run Disk Cleanup, empty temp folders, clear update cache, remove system restore points, and organize downloads.
Ideal For
Users with low storage, slow Windows performance, or C: drive running out of space.
Why Your Windows Drive Runs Out of Space — In-Depth Analysis
Before deleting files, understand which areas consume the most storage. This helps apply targeted cleanup steps that free the most space safely.
1. Temporary & Cached Files
Temporary files (system temp, app caches, browser caches) accumulate over time. These are safe to remove but can be large — especially browser caches and temporary installer files.
2. Windows Update & Component Store (WinSxS)
Windows keeps update files and a component store (WinSxS) used for repairs and servicing. Leftover update packages, especially after feature updates, can occupy several gigabytes.
3. Old System Restore Points and Shadow Copies
Restore points and Volume Shadow Copies are useful for recovery but can consume large portions of the system volume if not managed.
4. Hibernation File and Pagefile
Hibernation (hiberfil.sys) and Pagefile (pagefile.sys) are system files sized based on RAM. On systems with limited disk space and high RAM, these files can be significant.
5. User Folders (Downloads, Desktop, Videos)
Users often store installers, large videos, or compressed archives in Downloads or Desktop. Media folders (Videos, Pictures) can quickly fill the drive.
6. Applications & Optional Features
Installed apps, games, and optional Windows features take space. Some preinstalled apps and duplicates are rarely used but still occupy storage.
7. Duplicate Files and Old Backups
Multiple copies of photos, backups, and archive files often remain undiscovered and slowly eat storage.
8. Cloud Sync Folders (OneDrive, Dropbox)
Files synced for offline access replicate data locally. If 'Files On-Demand' is not used, cloud services can double local storage usage.
9. Log Files and Diagnostic Data
Large log files (e.g., Windows update logs, application logs) and diagnostic dumps (memory.dmp) are occasionally generated after crashes and can be removed if not needed for troubleshooting.
Expert Insights
Targeting the system areas above (temporary files, WinSxS, restore points, and large user folders) usually unlocks the most recoverable space without third-party tools. Always verify critical data before deletion and create a restore point or backup where necessary.
Priority Cleanup Targets (Estimated Space Yield)
- Temporary files & browser cache: 0.5–10+ GB
- WinSxS / Update cache: 2–30+ GB (varies with updates)
- Old restore points / shadow copies: 1–20+ GB
- Downloads & large media files: 1–100+ GB
- Hibernation & pagefile: Equal to RAM size (adjustable)
Case Scenarios Preview
Later in this guide we will show practical examples: a laptop with 32 GB reclaimed by cleaning WinSxS and removing old backups; an office PC where Downloads & OneDrive offline copies were the main culprits; and a gaming rig where large install caches were cleared safely.
Step-by-Step: How to Free Up Disk Space on Windows Without Software
Follow these built-in Windows methods to safely reclaim storage without third-party tools.
1. Use Storage Settings (Storage Sense)
Windows includes a native cleanup engine capable of deleting temporary files, old updates, and system junk.
- Open Settings → System → Storage.
- Enable Storage Sense.
- Click Temporary Files and select unnecessary files.
- Click Remove Files.
2. Clean Windows Update Residual Files
Windows Update keeps past installation files. Cleaning them can free multiple gigabytes.
- Open Settings → System → Storage → Temporary Files.
- Select Windows Update Cleanup.
- Click Remove Files.
3. Delete Temp Files Manually
Windows temporary directories can be cleared manually for deeper cleanup.
- Press Win + R, type
%temp%, and press Enter. - Select all files → Shift + Delete.
- Repeat with
tempandprefetchfolders.
4. Manage System Restore & Shadow Copies
- Press Win + R, type SystemPropertiesProtection.
- Select system drive → Configure.
- Click Delete to remove old restore points.
- Adjust max disk usage.
5. Reduce Hibernation File Size or Disable It
This can free space equal to 40–100% of your RAM size.
- Open Command Prompt as Administrator.
- To disable hibernation:
powercfg -h off - To reduce size:
powercfg /h /size 50
6. Analyse Large Folders Using Native Tools
Windows has built-in ways to detect what takes the most space without external apps.
- Go to Settings → System → Storage.
- Check Storage Breakdown by category.
- Inspect Apps & Features → uninstall unused programs.
- Review Downloads and Videos for large files.
7. Clean Cloud Sync Local Copies (OneDrive, Google Drive)
Huge space can be saved using “Files On-Demand”.
- Right-click OneDrive folder → Free up space.
- Enable Files On-Demand in OneDrive settings.
- Repeat for Google Drive (Stream mode).
8. Clear Browser Cache (Built-in)
- Open browser → Settings.
- Clear cache, temporary files, and unused site data.
9. Remove Old Device Drivers
Windows keeps old drivers after updates.
- Open Disk Cleanup → select system drive.
- Select Device Driver Packages.
- Click OK.
10. Delete Crash Dumps & Log Files
- Open Disk Cleanup → More Options.
- Select System error memory dump files.
- Remove diagnostic logs.
Analyst Notes
Most space is typically recovered through: deleting temporary files, cleaning Windows update cache, reducing hibernation size, and clearing Downloads/videos. For maximum efficiency, combine manual cleanup with Storage Sense automation.

Frequently Asked Questions (FAQ)
The quickest method is running Storage Sense, clearing Temporary Files, and cleaning the Downloads folder. These steps remove several gigabytes in minutes.
No. Temporary files are safe to delete. They include cache, logs, and update leftovers that Windows no longer needs.
This is usually caused by Windows Update leftovers, system restore points, temporary files, hibernation file growth, or large application caches.
Go to Settings → System → Storage → Temporary Files, then select Windows Update Cleanup and delete it. This can free up several GB.
Yes—if you don’t plan to revert to a previous Windows version. Deleting Windows.old can free 15–30 GB using Storage Cleanup.
Use Windows' built-in Storage Breakdown under Settings → Storage to view large files by category such as Videos, Documents, Temp, and Apps.
Yes. Disabling hibernation removes the hiberfil.sys file, which can be 3–10 GB depending on RAM size.
Browsers and programs store installers, PDFs, media files, and caches there. Enable Storage Sense → Automatic Cleanup to manage it.
Yes. Although legacy, Disk Cleanup can remove Windows Update files, temp files, and old installations effectively.
Light users: monthly.
Heavy users or creators: weekly.
Storage Sense can automate weekly or daily cleanup.
