How to Fix Not Enough Space to Install Windows 10 and 11

These tips and tricks show you how to Fix "Not Enough Space to Install Windows 10 and 11." Installing Windows 10 or 11 can be a smooth process, but encountering the dreaded “Not Enough Space to Install Windows 10” or  "Not Enough Space to Install Windows 11" error can be frustrating. Fear not! In this article, we’ll explore practical tips and tricks to help you make room for the Windows 10 installation and successfully install Windows 10 or 11.

1. Check Available Disk Space

Before anything else, verify that you have sufficient free space on your system drive. Windows 10 requires at least 16GB of free space for installation. Here’s how to check:

  • Press Win + E to open File Explorer.
  • Right-click on your system drive (usually C:) and select “Properties.”
  • Ensure you have enough free space. If not, consider deleting unnecessary files or moving data to an external drive.

2. Clean Up Temporary Files

Windows accumulates temporary files over time, hogging valuable space. Use the built-in Disk Cleanup tool:

  1. Press Win + S and search for “Disk Cleanup.”
  2. Select your system drive and click “OK.”
  3. Check the boxes for temporary files, system files, and anything else you want to clean.
  4. Click “OK” and let Windows do its magic.


3. Uninstall Unnecessary Programs

Review your installed programs and remove any you no longer need. Here’s how:

  • Go to “Settings” > “Apps” > “Apps & features.”
  • Scroll through the list and uninstall programs you rarely use.


4. Move Personal Files to Another Drive

If your system drive is still cramped, move personal files (documents, photos, videos) to an external drive or a different partition. You can also change the default location for new files:

  1. Go to “Settings” > “System” > “Storage.”
  2. Under “More storage settings,” click “Change where new content is saved.”
  3. Set a different drive for each file type (documents, pictures, videos).


5. Use External Storage

Consider using an external USB drive during installation. Windows allows you to choose a different drive for temporary files during setup. Connect the drive, select it during installation, and let Windows handle the rest.


6. Resize Partitions

If you have multiple partitions on your hard drive, consider resizing them. Use the built-in Disk Management tool:

  1. Press Win + X and select “Disk Management.”
  2. Right-click on a partition and choose “Shrink Volume” or “Extend Volume.”


7. Disable Hibernation

Hibernation files can consume significant space. Disable hibernation to free up room:

  1. Open Command Prompt as an administrator.
  2. Type powercfg /h off and press Enter.


8. Move Pagefile to Another Drive

The pagefile (virtual memory) can take up space. Move it to another drive:

  1. Go to “Settings” > “System” > “About.”
  2. Click “Advanced system settings.”
  3. Under the “Performance” tab, click “Settings.”
  4. Go to the “Advanced” tab and click “Change” under Virtual Memory.


9. Consider an SSD Upgrade

If you’re still struggling, upgrading to an SSD (Solid State Drive) can significantly improve performance and provide more space.


10. Clear System Restore Points:

  • System Restore points can consume considerable space. Adjust the maximum disk space allocated to System Restore or disable it if you have other backup solutions in place.

11. Use External Media for the Installation:

  • Instead of performing the Windows 10 upgrade directly, consider using external media like a USB drive. This can help bypass space limitations on your existing drive.

12. Perform a Clean Install:

  • If upgrading proves challenging, perform a clean installation of Windows 10. Back up your data, create a bootable USB drive, and install Windows 10 on a freshly formatted partition.


Resolving the "Not Enough Space to Install Windows 10" error requires a combination of freeing up disk space, optimizing storage usage, and considering hardware upgrades. By following these tips and tricks, you'll be better equipped to overcome space constraints and successfully install or upgrade to Windows 10. Remember to back up important data before making significant changes to your system.
