    How to Enable or Disable Reserved Storage for Windows Update in Windows 10

    Starting with the next major update Microsoft is making a few changes to how Windows 10 manages disk space. Through reserved storage, some disk space will be set aside to be used by updates, apps, temporary files, and system caches. Microsoft's goal is to improve the day-to-day function of your PC by ensuring critical OS functions always have access to disk space. 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 donít need to set anything upóthis process will automatically run in the background.

    The Reserved Storage feature is available for testing to Windows Insiders running build 18298 or newer.

    How does it work?
    When apps and system processes create temporary files, these files will automatically be placed into reserved storage. These temporary files wonít consume free user space when they are created and will be less likely to do so as temporary files increase in number, provided that the reserve isnít full. Since disk space has been set aside for this purpose, your device will function more reliably. Storage sense will automatically remove unneeded temporary files, but if for some reason your reserve area fills up Windows will continue to operate as expected while temporarily consuming some disk space outside of the reserve if it is temporarily full.

    Windows Updates made easy
    Updates help keep your device and data safe and secure, along with introducing new features to help you work and play the way you want. Every update temporarily requires some free disk space to download and install. On devices with reserved storage, update will use the reserved space first.

    When itís time for an update, the temporary unneeded OS files in the reserved storage will be deleted and update will use the full reserve area. This will enable most PCs to download and install an update without having to free up any of your disk space, even when you have minimal free disk space. If for some reason Windows update needs more space than is reserved, it will automatically use other available free space. If thatís not enough, Windows will guide you through steps to temporarily extend your hard disk with external storage, such as with a USB stick, or how to free up disk space.

    How much of my storage is reserved?
    In the next major release of Windows (19H1), Microsoft anticipates that reserved storage will start at about 7GB, however the amount of reserved space will vary over time based on how you use your device. For example, temporary files that consume general free space today on your device may consume space from reserved storage in the future. Additionally, over the last several releases weíve reduced the size of Windows for most customers. Microsoft may adjust the size of reserved storage in the future based on diagnostic data or feedback. The reserved storage cannot be removed from the OS, but you can reduce the amount of space reserved. More details below.

    The following two factors influence how reserved storage changes size on your device:
    • Optional features - Many optional features are available for Windows. These may be pre-installed, acquired on demand by the system, or installed manually by you. When an optional feature is installed, Windows will increase the amount of reserved storage to ensure there is space to maintain this feature on your device when updates are installed. You can see which features are installed on your device by going to Settings > Apps > Apps & features > Manage optional features. You can reduce the amount of space required for reserved storage on your device by Manage optional features"]uninstalling optional features you are not using.
    • Installed Languages - Windows is localized into many languages. Although most of our customers only use one language at a time, some customers switch between two or more languages. When additional languages are installed, Windows will increase the amount of reserved storage to ensure there is space to maintain these languages when updates are installed. You can see which languages are installed on your device by going to Settings > Time & Language > Language. You can reduce the amount of space required for reserved storage on your device by uninstalling languages you arenít using.

    I had enabled it on both Fast and Skippy builds, and just noticed today after build 18323 these tidbits.

    An 8GB VHDX (Virtual Hard Drive) allocated consuming almost no space. Just ID data.

    How it appears in Defrag and Optimize:

    Interesting. I was wondering how this was going to be implemented.

    Then next question would be what indicates to you that you have the 8GB reserved? Check this Reg key (from Shawn's tut above)

    HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion\ReserveManager

    ShippedWithReserves DWORD

    0 = Disable (default)
    1 = Enable



    If you just did this, in this build, it will will not appear until the next build update.

    Loads of free space but it could be the MBR/BIOS partition limitations? Just a guess. Will try and tidy up those two recovery partitions. Macrium backup first though!
