I am trying to update my ASUS laptop to windows 11. It just keeps saying it doesn't have enough storage space to complete it. I have done the clean ups with everything but still says it doesn't have enough space. I then bought a 60GB USB A memory stick to see if I can use that for extra storage for it to be able to update my laptop. It still just says not enough space... PLEASE HELP ME!!!

    Hi!

    Before offering any solution, I need to understand your current situation. Please provide more details about the issue you are experiencing. A good way to share this information is by answering the questions below:

    1. Are you currently using Windows 10 and looking to upgrade to Windows 11, or are you already using Windows 11 and trying to install an update (such as 25H2)?
    • Press Windows + R > Type winver > Press Enter > Please send me the Version and Build as shown in the image below. You can also send me a screenshot, but please remove any personal information from the image.

    1. How are you attempting to update to Windows 11 (Update Assistant, ISO, in-place upgrade, or Windows Update)? What is the full error message? Please send me a screenshot of the error, if possible.

    Finally, please show me your available storage space. Press Windows + E to open File Explorer > click on "This PC" > and send me a screenshot.

    With a Microsoft 365 Basic plan for $1.99/month, you can free up space in your Desktop, Pictures, and Documents folders by storing the data in the cloud. You can try it free for one month.

    With Files On-Demand, files stored in the cloud automatically download when you open them from your computer:

    Connect the USB drive, then select it through Settings > Windows Update > Fix issues; simply plugging it in does not automatically make its capacity available to the upgrade.

    Use the USB through Windows Update

    Your 60-GB USB has more than the required 10 GB of free external space. Proceed as follows:

    1. Back up any important files currently on the USB.
    2. Connect the USB directly to the laptop.
    3. Open Start > Settings > Windows Update.
    4. Select Fix issues beside the insufficient-space warning.
    5. The tool will show how much additional space is required.
    6. Select the USB drive from the drop-down list.
    7. Select Next and complete the upgrade.
    8. Leave the laptop connected to power and keep the USB inserted until installation finishes.

    This is Microsoft’s supported external-storage procedure.^1^

    Why the 60-GB USB may still not be enough

    Windows still requires some free space on the internal C: drive, even after external storage is selected. Depending on installed languages, optional features, drivers, and updates, Microsoft’s examples show approximately:

    • 4.5 GB or more internally for a minimal configuration using external storage.
    • 7 GB or more internally when more optional content is installed.

    The actual requirement can be higher, and Fix issues should display the amount needed for this laptop.^1^

    Since the general cleanups have already been completed, check the remaining capacity rather than repeating them:

    1. Open Settings > System > Storage.
    2. Note the total size and free space shown for C:.
    3. Compare its free space with the amount requested by Fix issues.

    If more internal space is still required, move large personal files—especially videos, Downloads, pictures, or documents—from C: to the USB. Copy them first, verify that they open from the USB, and only then remove the originals from the laptop.

    You can also check these targeted categories:

    • Settings > Apps > Optional features — remove only features you recognize and do not use.
    • Settings > Time & language > Language & region — remove unused language packs.

    Both can increase the storage required during a feature upgrade.^1^

    Check the laptop’s internal storage capacity

    Windows 11 requires a 64-GB-or-larger storage device. An external USB does not convert a smaller internal system drive into a supported 64-GB system drive.^2^

    Under Settings > System > Storage, if the internal drive’s total capacity, not merely its free space, is below 64 GB, this laptop does not meet the Windows 11 storage requirement. If it is at least 64 GB but Fix issues remains unavailable or still fails, record:

    • Total and free capacity of C:
    • Exact wording of the storage warning
    • Any error code
    • Current Windows version from Settings > System > About

    Those details distinguish a capacity limitation from a particular upgrade failure.
