For more information, see Free up space to install the latest Windows 10 update or visit the related FAQ. You can also take steps to free up space on your own. When updating, Windows will attempt to automatically free up enough hard drive space and guide you through freeing up even more if the automatic cleanup is not sufficient. Installing Windows or updating from a previous version of Windows on devices with less than 32GB storage will continue to work if the device has enough free space available. Starting with the May 2019 Update, the system requirements for hard drive size for clean installs of Windows 10 as well as new PCs changed to a minimum of 32GB. The 32GB or larger drive requirement is set to leave space for users to install apps and to keep data on the device. The factors that impact the amount of free hard drive space needed to take an update include: the versions of Windows previously installed on the machine, the amount of disk space available to reuse from Windows files, such as the virtual memory pagefile or hibernation file, which applications are installed on your device and how those applications store data.
