Last week, prior to releasing Windows 10 (19H1) Build 18312, Microsoft shared details about a new feature for the upcoming seventh feature update for the operating system called Reserved Storage.

The basic premise behind the feature is to set aside a certain amount of hard drive space that Windows 10 can use to insure future upgrades to the OS have plenty of space to be successful.

I shared my initial observations on Reserved Storage in Build 18312 last week when I updated my bare metal testing devices and a virtual machine on the Windows Insiders program.

With the release of Windows 10 (19H1) Build 18317 this week, I decided to go into each of those same systems and see how much the space set aside by Reserved Storage had changed from one build to the other.

Note: My virtual machine update is not yet complete for some reason so those details will be added once that cycle is complete.

HP EliteOne1K

Build 18312 – 2.50GB; Build 18317 – 7.05GB

HP Spectre x360 (2015)

Build 18312 – 5.61GB; Build 18317 – 6.64GB

Lenovo X1 Yoga

Build 18312 – 5.70GB; Build 18317 – 6.88GB

Surface Book

Build 18312 – 7.09GB; Build 18317 – 6.75GB

Virtual Machine

Build 18312 – 7.04GB; Build 18317 – 7.13GB

As you can see, some systems bumped up the amount of space they have set aside for Reserved Storage while others used up less space for the feature. 

I will be keeping an eye on this as the development for Windows 10 (19H1) wraps up to see how much this fluctuates from build to build over multiple updates.
