Fix - Windows Update Needs More Space
If you try to update windows and it tells you that Windows update needs more space, you can plug an external USB thumb drive into your computer and use it for the extra space during the update. This happens when there isn't enough hard drive space for windows to update itself. Insert the USB thumb drive into your computer and then Microsoft windows will update properly, using the USB thumb drive to store extra and back up files. After the update is completed and your computer has been restarted, you can remove the thumb drive from the computer. That is how to fix your Microsoft Windows 10 computer when it won't update because windows update needs more space.
