Windows 10 version 1903 will retain 7GB of disk space to maintain system updates
The latest news from the official Microsoft blog shows that Windows 10 Version 1903 will use temporary files to fill the disk to preserve space updates.
Microsoft said that the new version will retain at least 7GB of disk space to maintain the normal update of the system. Usually, this part of the space will be filled with similar files by temporary files.
Under normal circumstances, if there is insufficient system space, there is no way to update automatically, because you need to download a large number of files to the local and then install.
“Starting with the next major update we’re making a few changes to how Windows 10 manages disk space. Through reserved storage, some disk space will be set aside to be used by updates, apps, temporary files, and system caches. Our goal is to improve the day-to-day function of your PC by ensuring critical OS functions always have access to disk space. Without reserved storage, if a user almost fills up her or his storage, several Windows and application scenarios become unreliable. Windows and application scenarios may not work as expected if they need free space to function. With reserved storage, updates, apps, temporary files, and caches are less likely to take away from valuable free space and should continue to operate as expected. Reserved storage will be introduced automatically on devices that come with version 1903 pre-installed or those where 1903 was clean installed. You don’t need to set anything up — this process will automatically run in the background. The rest of this blog post will share additional details on how reserved storage can help optimize your device.”
“When apps and system processes create temporary files, these files will automatically be placed into reserved storage. These temporary files won’t consume free user space when they are created and will be less likely to do so as temporary files increase in number, provided that the reserve isn’t full. Since disk space has been set aside for this purpose, your device will function more reliably. Storage sense will automatically remove unneeded temporary files, but if for some reason your reserve area fills up Windows will continue to operate as expected while temporarily consuming some disk space outside of the reserve if it is temporarily full.”
Microsoft dynamically adjusts the reserved space according to the actual situation of Windows 10 versions. 7GB is the reserved space of Windows 10 Version 1903.
