    My Windows 10 Pro 1803 release only has 256MB of System Reserve area. After making all the update changes to 1803, I started the 1903 update which ran fine until it said the System Reserve area was to small. The new 1903 needs at least 450MB of Reserve Area. I have a system with a 320GB hard drive and have room to spare.
    My question is how can I increase the size of my system reserve area to around 600MB? I had backed up my system and used a free software package called Mini Partition Magic. I shifted my system partition to make room for the extended System Reserve area and ran it. Twice the Windows system 10 Pro fails to complete and I lose both my original system reserve area and my Windows system 10. I have a cloning software so I can rebuild my 320GB hard drive. Now I'm updating the 1903 Windows 1o Pro, but what do I do when it sends a message that the System Reserve area needs to be extended?

    try launching setup with parameters i.e.
    if using explorer, browse to iso folder having setup.exe, shift+right-click an empty space - Open Powershell/Command Prompt here
    then enter: cmd /c setup.exe /ResizeRecoveryPartition disable

    What does "System Reserve area" mean?
    Are you thinking?
    1. System Reserved partition (A System Reserved partition, a Windows partition that is created when you clean install Windows 7/8/10, contains necessary files to boot your computer.)
      or you mean
    2. Reserved Storage of Windows 10 version 1903 which size is 7GB

    As he has 1803, not 1903, it can only be the System Reserved boot partition.

    Might think so, but the size of this partition is determined by Windows if there is enough free space on the disk. Its default size is 536MB for Windows 10, 100MB for Windows 7 and 350MB for Windows 8. And its name is Healthy (Recovery Partition).
    I wonder, in the first post has been said there is 286MB, how it's possible if currently is installed Windows 10 Pro 1803.

    Might be an upgraded system. As long as there's enough space on the System Reserved partition, Setup will not complain nor change anything, there.

    Resizing manually might not work with every tool. The partition type for the reserved partition is 0x27 (Hidden RE). When I have to resize it, I first change the partition type to 0x07 (NTFS), resize, and then change it back to 0x27 (Hidden RE).

    I was able to increase the size of the system reserved partition which was around 245mb to over 600mb. Using Mini Partition Magic I created another partition after the Windows 10 Pro Partition for 600mb. I copied the original system reserved partition which I gave it a "E" name to the new partition which I gave it a "Y" name. Rebooted my system and it recognised the new 600mb system reserved area, and from here I was able to update the Dell Windows 10 Pro to 1903.

    This thread is not about what Microsoft does with Reserved Storage in the future, its about whats happening in real life today. This thread was written because I spent Hours building a Windows 10 Pro from Windows 7 for gifting laptops to high school students. The software on the Dell Latitudes are extensive, and I have no intention of going back everytime Microsoft updates their software. I use cloning software to replicate all the laptops I gift. I did download the Mediation Creation tool for 1903, and all it gave me was a bare bones Windows 10 Pro with the updated System Reserve area. I have no intention of reinstalling all the software I have installed over the past 4 years for these high school students.
    So in the future if Microsoft screws around with updates that won't allow my software to move forward. I'll find ways around them just like I did between their 1803 and 1903 updates.
