In the Next Update, Windows 10 Will Set Aside at Least 7GB Disk Space for Updates, Cache

Microsoft is working now on a feature for Windows 10 that will set aside ‘reserve space’ on every computer. Microsoft hopes this reserve space will help make Windows 10 computers more reliable, allowing updates, apps, cache, and temporary files to have an adequate environment to operate.

The company says that reserve space will begin at about 7GB but will act dynamically to increase when needed based on how often and how much the computer is used.

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.
