Without sufficient space, the update process can be halted, leaving your system stuck and preventing you from enjoying the latest features and security improvements of Windows 11.

This guide provides comprehensive solutions to address the “Setup needs space to update” error, enabling you to free up necessary disk space and proceed with your Windows 11 update seamlessly. These methods are designed to help you reclaim storage space by removing unnecessary files, managing system features, and optimizing your drive, ensuring your system meets the space requirements for a successful update. By following these steps, you can overcome this common update hurdle and keep your Windows 11 system up-to-date and performing optimally.

Fix Setup needs space to update Windows 11/10¶

When confronted with the “Setup needs space to update” message during a Windows 11/10 installation or update, it’s crucial to take immediate steps to liberate disk space. Insufficient storage is a primary impediment to a successful update, and resolving this issue is paramount. Here are several effective strategies to free up disk space on your system and pave the way for a smooth update process:

1. Use Disk Cleanup
2. Disable Page file and Hibernation
3. Delete System Restore Points and disable System Protection
4. Delete unused or inactive profiles
5. Miscellaneous steps to free up space on the C drive

Let’s delve into each of these methods to understand how they can contribute to freeing up valuable disk space.

1] Use Disk Cleanup¶

Disk Cleanup is an invaluable built-in utility within Windows 11, meticulously designed to assist users in reclaiming storage space on their hard drives or SSDs. It achieves this by identifying and removing files that are no longer necessary or are considered junk, which accumulate over time and consume precious disk space. Accessing Disk Cleanup is straightforward; simply utilize the Windows 11 Search bar, type “Disk Cleanup,” and select the utility from the search results.

Upon launching Disk Cleanup, it initially scans your primary drive, typically the C drive, for common types of unnecessary files, such as temporary internet files and downloaded program files. To maximize its effectiveness, it’s essential to utilize the “Clean up System Files” option. This action relaunches the tool with elevated privileges, allowing it to scan and clean up system-related files that standard Disk Cleanup might overlook. After relaunching, ensure that your C drive is selected for cleanup and proceed by clicking “OK.”

This deeper scan will uncover additional categories of files that can be safely removed, potentially freeing up a significant amount of space. These categories may include:

• Windows Update log files: These files are generated during Windows updates and can grow considerably over time. Removing them will not affect your system’s stability or future updates.
• System error memory dump files: These files are created when your system encounters a critical error (BSOD). While they can be useful for troubleshooting, they often consume substantial disk space and are generally safe to delete if you are not actively troubleshooting system crashes. However, be aware that deleting these files will hinder your ability to diagnose past Blue Screen of Death (BSOD) errors.
• Temporary files: Windows and applications often create temporary files that are meant to be automatically deleted, but sometimes they linger. Disk Cleanup can effectively remove these files.
• Recycle Bin: Files that you have deleted are moved to the Recycle Bin. Disk Cleanup can empty the Recycle Bin, permanently deleting these files and freeing up the space they occupied.
• Thumbnails: Windows creates thumbnail images for files to speed up visual browsing. These thumbnails can accumulate and take up space, and Disk Cleanup can remove them.

Carefully review the list of file categories presented by Disk Cleanup. While some options are pre-selected as safe to delete, you can choose additional categories to maximize space reclamation based on your needs and understanding of the file types. After selecting the desired categories, click “OK” to initiate the cleanup process. Once completed, check if you can now proceed with the Windows 11 update.

2] Disable Page file and Hibernation¶

If the “Setup needs space” error persists even after using Disk Cleanup, it indicates a need for more aggressive space-saving measures. In such scenarios, disabling the Page file and Hibernation features can be effective, particularly on the C drive where Windows is installed. It’s important to understand that while the Page file is generally recommended to be enabled for efficient virtual memory management, and hibernation is a convenient power-saving feature, temporarily disabling them can free up a significant amount of disk space.

The Page file (also known as the swap file) is a hidden system file on your hard drive that Windows uses as an extension of RAM. When your system’s physical RAM is fully utilized, Windows moves less frequently used data from RAM to the Page file to free up RAM for active processes. The size of the Page file can be substantial, often several gigabytes, depending on your system’s RAM and usage patterns.

Hibernation is a power-saving state that saves the current state of your system (including open applications and documents) to your hard drive and then shuts down your computer completely. When you resume from hibernation, your system restores to its previous state quickly. The hibernation file (hiberfil.sys) typically occupies space equivalent to a significant portion of your system’s RAM.

Disabling both the Page file and Hibernation can free up a considerable amount of disk space, especially if your system has a large Page file and hibernation file. However, it’s crucial to remember that disabling the Page file can potentially impact system performance if your system frequently relies on virtual memory. Similarly, disabling hibernation will remove the hibernation option and may slightly increase boot times from a completely powered-off state.

To disable the Page file, follow these detailed steps:

1. Open Windows 11 Settings: The quickest way is to press the Windows key + I simultaneously.

2. Navigate to System > About: In the Settings app, click on “System,” and then select “About” from the left-hand menu.

3. Access Advanced System Settings: On the “About” page, look for and click on “Advanced system settings” under the “Device specifications” section. This will open the “System Properties” window.

4. Go to the Advanced Tab: In the “System Properties” window, navigate to the “Advanced” tab.

5. Performance Settings: Under the “Performance” section, click the “Settings” button. This will open the “Performance Options” window.

6. Advanced Performance Options: In the “Performance Options” window, go to the “Advanced” tab.

7. Virtual Memory Settings: Under the “Virtual memory” section, click the “Change” button. This will open the “Virtual Memory” window.

8. Disable Automatic Paging File Management: At the top of the “Virtual Memory” window, uncheck the box labeled “Automatically manage paging file size for all drives”. This is a crucial step to allow manual configuration of the Page file.

9. Select the C Drive: In the list of drives, select the C drive (or the drive where your Windows is installed).

10. Disable Paging File on C Drive: Choose the “No paging file” option and then click the “Set” button. You might receive a warning message; click “Yes” to confirm.

11. Confirm and Apply Changes: Click “OK” in the “Virtual Memory” window, then “OK” in the “Performance Options” window, and finally “OK” in the “System Properties” window. You will likely be prompted to restart your computer for the changes to take effect.

To disable Hibernation, you can use the Command Prompt:

1. Open Command Prompt as Administrator: Type “cmd” in the Windows Search bar, right-click on “Command Prompt,” and select “Run as administrator”.

2. Disable Hibernation Command: In the Command Prompt window, type the following command and press Enter:
   

   powercfg -h off
   

After disabling both the Page file and Hibernation, check if you have freed up enough space to proceed with the Windows 11 update. Crucially, after successfully updating Windows 11, it is highly recommended to re-enable the Page file (by reversing the steps above and selecting “System managed size” or “Custom size”) and re-enable Hibernation (by running powercfg -h on in an administrator Command Prompt) to restore optimal system performance and power-saving capabilities.

3] Delete System Restore Points and disable System Protection¶

System Restore is a valuable feature in Windows that creates “restore points,” which are essentially snapshots of your system’s configuration at a specific point in time. These restore points allow you to revert your system back to a previous working state if you encounter problems after installing new software, drivers, or updates. However, these restore points consume disk space, and if disk space is critically low, managing or deleting them can be a viable strategy.

To assess and manage System Restore points:

1. Open System Protection Settings: Type “Create a restore point” in the Windows Search bar and select the matching result, “Create a restore point”. This will open the “System Properties” window directly to the “System Protection” tab.

2. Configure System Protection for C Drive: In the “System Protection” tab, select your C drive (or the drive where system protection is enabled) from the list and click the “Configure” button.

3. Review Current Disk Space Usage: In the “Configure System Protection for Local Disk (C:)” window, you will see a section labeled “Disk Space Usage.” This section displays the current space being used by restore points and the maximum space allocated for System Restore. Note the current usage to understand how much space is being consumed by restore points.

If you find that System Restore points are occupying a significant portion of your C drive, you have two primary options to free up space:

• Delete all Restore Points: To immediately reclaim the space used by all existing restore points, click the “Delete” button in the “Configure System Protection” window. A confirmation prompt will appear; click “Continue” to proceed with deleting all restore points. This action will remove all existing restore points, freeing up the disk space they occupied.

• Turn Off System Protection: Alternatively, you can completely disable System Protection for the C drive. In the “Configure System Protection” window, select the “Disable system protection” option and click “Apply” and then “OK”. Disabling System Protection will not only delete all existing restore points but also prevent the system from creating new restore points in the future.

Important Considerations regarding System Protection:

• Risk of Disabling: Disabling System Protection does come with a risk. If you encounter system problems after disabling it, you will not be able to use System Restore to revert to a previous state. Therefore, it’s generally recommended to disable System Protection only temporarily to free up space for the Windows update and re-enable it afterwards.
• Re-enabling System Protection: After successfully updating Windows 11, it is strongly advised to re-enable System Protection. To do this, return to the “System Protection” configuration for the C drive and select “Turn on system protection”. You can also adjust the “Max Usage” slider to control how much disk space is allocated for restore points in the future.

By deleting restore points or temporarily disabling System Protection, you can potentially free up a substantial amount of disk space. After taking these steps, check if you now have sufficient space to update Windows 11. Remember to re-enable System Protection after the update to maintain system recoverability.

4] Delete unused or inactive profiles¶

Windows 11’s multi-user capability allows for the creation of multiple user profiles on a single system. Each user profile has its dedicated folder located on the C drive (C:\Users\<Username>), which stores personal documents, settings, desktop customizations, and application data specific to that user. Over time, if user profiles are created and then become unused or inactive, they continue to occupy disk space on the C drive. Deleting these unnecessary profiles can contribute to freeing up valuable storage.

To identify and delete unused or inactive user profiles:

1. Open System Properties (Advanced): Right-click on the “This PC” icon on your desktop or in File Explorer, select “Properties,” and then click on “Advanced system settings” in the left-hand menu. This will open the “System Properties” window.

2. User Profiles Settings: In the “System Properties” window, go to the “Advanced” tab. Under the “User Profiles” section, click the “Settings” button. This will open the “User Profiles” window, displaying a list of all user profiles stored on the computer.

3. Identify Unused Profiles: In the “User Profiles” window, review the list of profiles. Pay attention to the “Last Used” column, which indicates the date when each profile was last accessed. Profiles with significantly old “Last Used” dates are likely inactive or unused. Also, consider the profile names to identify accounts that are no longer needed (e.g., profiles for former family members or colleagues).

4. Delete Unused Profiles: Select the user profile you want to delete (ensure it is an unused or inactive profile and NOT your current active profile or any profile that is still in use). Click the “Delete” button.

5. Confirmation and Deletion: You will be prompted to confirm the deletion. Be absolutely certain that you are deleting an unused profile and that no important data is stored within it. Deleting a user profile is a permanent action and will remove all associated data and settings for that profile. Click “Yes” to confirm and proceed with the deletion.

6. Repeat for Other Unused Profiles: Repeat steps 4 and 5 for any other unused or inactive user profiles you wish to delete.

Important Precautions before Deleting User Profiles:

• Backup Important Data: Before deleting any user profile, especially if you are unsure about its contents, it is crucial to back up any potentially important data from that profile. Check the “Documents,” “Desktop,” “Downloads,” “Pictures,” and other folders within the user profile directory (C:\Users\<Username>) for any files you might need. Copy these files to a safe location, such as an external drive or cloud storage.
• Do Not Delete Active Profile: Never delete the user profile that you are currently logged into or any profile that is actively being used. Deleting an active profile can lead to system instability and data loss.
• Administrator Privileges: You need administrator privileges to delete user profiles.

Deleting unused user profiles can free up a significant amount of disk space, especially if these profiles contain substantial amounts of data. After deleting the profiles, check if you have gained enough space to proceed with the Windows 11 update.

5] Miscellaneous steps to free up space on the C drive¶

In addition to the more systematic methods described above, several miscellaneous actions can contribute to freeing up additional space on your C drive. These steps, while individually might not reclaim vast amounts of space, can collectively make a noticeable difference and are often quick and easy to implement.

• Empty Recycle Bin: The Recycle Bin is a temporary storage area for deleted files. Files moved to the Recycle Bin are not actually deleted from your hard drive until the Recycle Bin is emptied. To empty the Recycle Bin and permanently delete these files:

  • Locate the Recycle Bin icon on your desktop.
  • Right-click on the Recycle Bin icon.
  • Select “Empty Recycle Bin”.
  • Confirm the deletion when prompted.

• Delete Temporary Files: Temporary files are created by Windows and applications for various purposes. Over time, these files can accumulate and consume disk space. To delete temporary files:

  • Press Windows key + R to open the Run dialog box.
  • Type %temp% (including the percentage signs) and press Enter or click “OK”. This will open the Temp folder in File Explorer.
  • Select all files and folders within the Temp folder (Ctrl+A).
  • Press the Delete key.
  • Some files might be in use and cannot be deleted. If you encounter such prompts, select “Do this for all current items” and click “Skip” to skip those files.

• Uninstall Unused Programs: Applications that you no longer use are still installed on your system and occupy disk space. Uninstalling these programs can free up space. To uninstall programs:

  • Open Windows 11 Settings (Windows key + I).
  • Click on “Apps” and then “Installed apps” (or “Apps & features” in older Windows versions).
  • Scroll through the list of installed apps.
  • Identify programs that you no longer need or use.
  • For each program you want to uninstall, click the three dots (more options) next to the program name and select “Uninstall”.
  • Follow the on-screen prompts to complete the uninstallation process.

• Consider Third-Party Disk Cleanup Utilities: While Disk Cleanup is a built-in Windows tool, numerous third-party disk cleanup and system optimization utilities are available. Some of these utilities may offer more advanced features and potentially identify and remove more types of unnecessary files than the built-in Disk Cleanup. However, exercise caution when using third-party utilities. Only use reputable and well-known software from trusted sources. Some utilities might bundle unwanted software or be ineffective. Research and read reviews before using any third-party disk cleanup tool.

By implementing these miscellaneous steps in conjunction with the more comprehensive methods outlined earlier, you can maximize your efforts to free up disk space on your C drive and increase your chances of successfully updating to Windows 11.

How do I free up 10 GB of space on Windows?¶

Freeing up 10 GB of space on a Windows system is often achievable by employing a combination of the methods discussed above. However, the ease and speed with which you can reach this target depend on several factors specific to your system and usage:

• Current Disk Usage: If your hard drive or SSD is already quite full, freeing up 10 GB might require more effort and a combination of several techniques. If you have a lot of readily deletable unnecessary files, temporary files, or unused programs, achieving 10 GB might be relatively quick.
• Types of Files Stored: The types of files consuming your disk space significantly impact how easily you can free up space. If a large portion of your drive is used by personal documents, photos, videos, or large applications that you need, freeing up 10 GB might necessitate moving some of these files to external storage or cloud services. If, however, your drive is filled with temporary files, system junk, and unused programs, Disk Cleanup and uninstalling applications can quickly reclaim substantial space.
• Partition Size and Structure: The size and partitioning of your hard drive also play a role. If you are trying to free up space on the C drive specifically (where Windows is installed), you are limited to removing files from that partition. If you have other partitions, you might consider moving data from C to other partitions if possible, although this might not directly help with the “Setup needs space to update Windows 11” error, which typically requires free space on the C drive.

Strategies to Free Up 10 GB or More:

1. Aggressive Disk Cleanup: Utilize Disk Cleanup, including the “Clean up System Files” option, and select all relevant categories, including Windows Update logs, system error memory dump files, temporary files, Recycle Bin, and potentially even thumbnails.
2. Disable Page File and Hibernation (Temporarily): Disabling these features, especially if you have a large amount of RAM, can immediately free up several gigabytes of space. Remember to re-enable them after the update.
3. Delete System Restore Points: Deleting all restore points can reclaim a significant amount of space, depending on how much space is allocated to System Restore.
4. Uninstall Large Unused Programs: Identify and uninstall several large applications that you no longer use. Focus on applications that are known to be space-intensive, such as games, video editing software, or large utilities.
5. Move Personal Files to External Storage: If possible and practical, move large personal files (documents, photos, videos, music) from your C drive to an external hard drive, USB drive, or cloud storage service.
6. Analyze Disk Space Usage: Use a disk space analyzer tool (many free tools are available online) to get a visual representation of how your disk space is being used. These tools can help you identify the largest folders and files, allowing you to target space-saving efforts more effectively.
7. Empty Downloads Folder: The Downloads folder often accumulates large files downloaded from the internet that are no longer needed. Regularly check and empty this folder.

By systematically applying these methods, you should be able to free up 10 GB of space or more on your Windows system, provided that there is enough removable data available. Start with the safest and easiest methods (Disk Cleanup, Recycle Bin, Temp files) and then proceed to more impactful but potentially temporary measures (Page file, Hibernation, System Restore) if needed.

How to fix We can’t tell if your PC has enough space to continue installing Windows 11?¶

The error message “We can’t tell if your PC has enough space to continue installing Windows 11. Try restarting Setup” is a variation of space-related update errors and often arises due to insufficient disk space on the partition where Windows 11 is being installed, typically the C drive. While the message suggests restarting setup, simply restarting the setup process without addressing the underlying space issue is unlikely to resolve the problem. The error message itself is somewhat misleading, as the core issue is almost always a lack of disk space, rather than an inability to “tell” if there is enough space.

Troubleshooting and Solutions:

1. Confirm Disk Space Shortage: First, verify that you are indeed running low on disk space on your C drive. Open File Explorer, go to “This PC,” and check the free space available on your C drive. Compare this to the minimum space requirements for Windows 11 updates (which can vary but are generally several gigabytes). If you see very little free space (e.g., less than 5-10 GB), then disk space is very likely the root cause.

2. Apply Space-Freeing Methods: Implement the disk space freeing methods detailed in the previous sections of this guide. Prioritize the following:

   • Disk Cleanup (including System Files Cleanup)
   • Empty Recycle Bin and Delete Temp Files
   • Uninstall Unused Programs
   • Consider deleting System Restore Points or temporarily disabling System Protection

3. Restart Your Computer: After freeing up a significant amount of disk space (aim for at least 10-20 GB free if possible to be safe), restart your computer. This ensures that the system recognizes the newly freed space and that any temporary files or processes that might have been contributing to the error are cleared.

4. Restart Windows 11 Setup: After restarting your computer, attempt to run the Windows 11 update setup again. If you were using Windows Update in Settings, go back to Settings > Windows Update and click “Check for updates” or “Download and install.” If you were using a Windows 11 Installation Assistant or Media Creation Tool, restart that process.

5. Check for Conflicting Applications: In some rare cases, certain third-party applications might interfere with the Windows update process. If the error persists even after freeing up space, consider temporarily uninstalling any recently installed or potentially problematic applications (especially system utilities, antivirus software, or disk management tools). You can reinstall them after the update is successful.

6. Run System File Checker (SFC): Corrupted system files can sometimes cause update errors. Run the System File Checker tool to scan for and repair corrupted system files:

   • Open Command Prompt as Administrator (search for “cmd,” right-click, “Run as administrator”).
   • Type sfc /scannow and press Enter.
   • Allow the scan to complete and follow any on-screen instructions.

7. Check Disk for Errors: Disk errors on your hard drive or SSD can also interfere with updates. Use the Check Disk utility to scan for and repair disk errors:

   • Open File Explorer, right-click on your C drive, select “Properties,” go to the “Tools” tab, and click “Check” under “Error checking.”
   • Follow the on-screen prompts to scan and repair the drive.

By systematically addressing potential disk space issues and considering other possible factors like conflicting software or system file corruption, you should be able to resolve the “We can’t tell if your PC has enough space…” error and successfully install or update to Windows 11. In the vast majority of cases, freeing up sufficient disk space is the primary solution.

We hope this guide has provided you with the necessary steps to resolve the “Setup needs space to update Windows 11” error and similar space-related update issues. By diligently following these methods, you can effectively manage your disk space and ensure a smooth and successful Windows 11 update experience.
