Windows 10 2019 May edition update (version 1903) comes with a new feature called “reserved storage”, It retains part of the system storage to ensure Windows Update and drivers The program works reliably when there is insufficient space.
The reserved storage introduced in Windows 10 version 1903 will continue to exist. By default, about 7GB of hard disk space should be used. When you add optional features, install other drivers, or enable new language packs, the reserved space may be bigger.
Microsoft says that reserved storage will ensure that Windows updates go smoothly. Then users will not encounter any critical storage issues. Many people may not be satisfied with reserved storage, especially when PC manufacturers provide recovery drives and take up to 15GB Space on the device.
Users can free up reserved storage by adjusting the registry before, but you may already know that editing the registry may cause serious problems. An incorrect edit in the registry may render the Windows computer unusable or unable to start.
Microsoft plans to introduce new DISM tools in Windows 10 v1903, v1909 and v2004 to make this process more secure through the command line.
Users will update the DISM tool to better control the reserved storage space. The updated command-line-based DISM tool will be available in Windows 10 versions 1903, 1909, and 2004 later this year.
With DISM tool support, you will be able to determine whether the PC is using reserved storage. You can also use it to enable or disable reserved storage.
This feature is already a real-time preview version of Windows 10 20H1, and Microsoft plans to introduce it to an earlier version of Windows 10 soon.
DiAcetis (The Principal Program Manager of Microsoft) said: “These new commands are only available in Windows 10 version 2004. We are considering introducing them to earlier versions, but there is no timetable to share.”
This is a useful tool that will eventually help you recycle reserved storage and will be available to everyone later this year.
