Table of Contents
The lighter your Windows setup, the better your PC will perform. By removing unnecessary files and trimming background processes, you can free up memory, cut boot times, and reduce CPU load.
If your C drive is running low on space, every gigabyte matters. Windows itself can easily take up more than 25 GB with updates, restore points, and cache files. Add in pre-installed bloatware, and storage fills up quickly—especially on laptops with 128 GB SSDs or devices with soldered memory. Even on well-equipped systems, decluttering Windows is worth it.
⚠️ Important: Not all steps are risk-free. Removing certain components or libraries can make Windows unstable, cause updates to fail, or break apps. Always create a restore point and back up your system before making changes.
Quick Start: Clear Temporary Files and Update Leftovers
Begin with Windows’ built-in Disk Cleanup tool. Run it via cleanmgr or through the C drive properties. Check all boxes, including “Update Cleanup.” Skip “Downloads” if you still use that folder, and don’t forget to empty the Recycle Bin.
Next, open Settings → System → Storage → Storage Sense and enable automatic cleanup. Under “Advanced storage settings,” you can also manage other drives. Together, these steps can instantly free up several gigabytes.
Remove Search Index and Update Buffer
The Windows Search Index can take up gigabytes over time. The “Windows.edb” file (found at %ProgramData%\Microsoft\Search\Data\Applications\Windows) grows continuously. If you use a tool like Everything for searching, you can safely disable the Windows Search service and delete the file.
Windows also reserves up to 7 GB for updates. To reclaim it, run PowerShell as administrator and use:
Set-WindowsReservedStorageState -State Disabled -Online
This frees the space, but you’ll need enough free storage for future updates.
Compress System Files with CompactOS
Windows includes a hidden feature called CompactOS. Run this command in Command Prompt:
compact /compactOS:always
This compresses system files and typically saves 2–6 GB. You can disable it anytime with:
compact /compactOS:never
To check status:
compact /compactOS:query
For more control, tools like CompactGUI and Compactor allow you to compress individual folders using algorithms like XPRESS4K (fast) or LZX (best compression). Games and large programs like Visual Studio or Adobe tools can shrink by 40–60%.
⚠️ Avoid compressing certain formats (e.g., SQLite databases, VMs, DirectStorage-based games) since performance may drop.

Tiny11: A Lightweight Windows 11
Tiny11 is a stripped-down Windows 11 build without TPM, online account requirements, or bloatware. With LZX compression, it can be as small as 3.5 GB. You can either download it from the Internet Archive or create your own ISO using Tiny11 Builder.
Once built, write the ISO to a USB stick with Rufus and install Windows offline to set up a local account.
WinUtil: Automated Minimal Windows
If you’d rather not tinker, WinUtil by Chris Titus creates preconfigured lightweight Windows builds. They skip TPM checks, online accounts, and cut memory usage by half compared to a normal install.
More Minimal Options
Tiny11 Core
Removes Windows Defender, updates, and recovery mode. Very light but not updateable.
VHD Installations
Use WinNTSetup to run Windows directly from a virtual hard disk—great for testing.
Debloating Tools
- Win11Debloat removes apps like Xbox, OneDrive, Cortana, and Edge.
- Win Reduce cuts deeper by shrinking core system folders (e.g., WinSxS, System32). Only for experts, as updates will no longer work.
Build Your Own Minimal Windows
- Win10XPE + PEBakery lets you create a portable Windows ISO that runs entirely in RAM—perfect for old PCs or emergency use.
- NTLite customizes official Windows ISOs by removing apps, services, or language packs while keeping it legal.
- WinScript offers an easy GUI to remove apps, tweak privacy, disable telemetry, and improve performance. It also creates restore points automatically.

Other Quick Space-Savers
- Disable hibernation:
powercfg -h off(saves up to 4 GB). - Move page file to another drive:
sysdm.cpl ,3. - Reduce System Restore space:
sysdm.cpl ,4 → Configure. - Turn off update delivery optimization under Windows Update → Advanced options → Delivery Optimization.
Final Thoughts
With the right tweaks, you can make Windows PC faster and lighter, improving performance and efficiency. Just remember to back up your system first and apply these steps carefully.
FAQs
1. How can I make Windows PC faster without software?
You can make Windows PC faster by using built-in tools like Disk Cleanup, Storage Sense, and CompactOS. Removing temporary files, disabling unnecessary startup apps, and freeing up storage can improve speed without installing third-party software.
2. Does compressing system files slow down Windows?
No, using CompactOS does not slow down Windows. The feature is designed to compress system files without affecting performance. However, avoid compressing databases, virtual machines, or DirectStorage-based games as they may run slower.
3. Is Tiny11 safe to use for better performance?
Tiny11 is a modified version of Windows 11 that removes bloatware, TPM checks, and other heavy features. It is lightweight and makes your PC run faster, but since it’s not an official Microsoft build, use it only if you understand the risks.
4. Can I make Windows PC faster by disabling updates?
Disabling updates may temporarily make Windows PC faster by reducing background processes, but it’s not recommended. Updates provide security patches and bug fixes. Instead, you can reclaim space by disabling reserved storage for updates.
5. What is the quickest way to free up space on Windows?
The quickest way is to run Disk Cleanup or enable Storage Sense. These tools delete temporary files, cache, update remnants, and empty the recycle bin, freeing up several gigabytes instantly.
6. Does debloating Windows improve speed?
Yes, removing unnecessary apps and background services with tools like Win11Debloat or WinUtil helps make Windows PC faster. However, be careful not to remove system-critical components.
