Upcoming builds of Windows 10 will support a new feature designed to ensure system updates occur more smoothly. Reserved Storage will ensure there's enough free space on your hard drive so that system updates can download and install seamlessly.
Windows 10 Build 19H1 will set aside disk space for system updates, applications, temporary files and system caches.
That will help your system run more efficiently and ensure you can download the latest fixes and patches so your system stays up to date and dafe from the latest security vulnerabilities.
According to a blog post about the Reserved Storage feature it will be available on all systems that come with version 1903 pre-installed or those where 1903 was clean installed. Initially, the space allocated will be about 7GB although that will change depending on how you use your system.
Reserved Storage works by allowing the Windows file system, NTFS, to use a mechanism that allows it specify how much space it needs reserved, say 7GB, for system services. Then NTFS reserves that 7GB for servicing usage only with the available capacity on C: reduced by 7GB.
If you're a Windows Insider, Reserved Storage is available to those running Build 18298 or later. Although you'll also need to complete a quest in order for Reserved Storage to be unlocked.
As the complexity of our working environments increases and more and more security threats emerge, it's more important than ever to keep your system up to date. By ensuring computers running Windows 10 are always able to download and install updates, Microsoft is improving the update process. That's good news for users although the 7GB storage hit may be a challenge for those with smaller drives. Lots of computers, particularly entry level laptops and convertibles have been sold with just 128GB of SSD storage and 7BG is a decent hit on that.
How windows 10 will manage that on systems with just 64BG, or even 32GB that we see on some super cheap systems, remains to be seen.
