Important information about devices that have low disk space
When a Windows feature update is available for your device, you may see a message on the Windows Update settings page or elsewhere that asks you to free up disk space by removing files or applications that you do not use regularly. If you see this message, select Fix issues to free up disk space on your device.
To help free up disk space, this update may compress files in your user profile directory so that Windows Update can install important updates. When files or folders are compressed, they appear as having two blue arrows overlaid on the icon. Depending on your File Explorer settings, you may see icons that look larger or smaller. The following screen shot shows an example of these icons.
After you install the update, your files are restored to their original state, and the blue arrows disappear from the file icons in File Explorer. At any point during the update process, you should be able to access your files.
