Windows 10: reserved storage space and May 2020 update questions.

JohnKeubler · Jun 11, 2020

I have a question. I have a dell inspiron 3542 2 gb ram, 32 gb. Emmc storage notebook. Last month I had 12 gb. free storage. I did the May 2020 cumulative security update and it used up 3 gb. of storage. I now have 8.84 gb. free. After June 2020 security update, now 8.24 gb. free space. I cannot reclaim this through disk cleanup or turn off reserve storage. It is not that important right now but I don't have a big emmc storage capacity. The April 2020 security updates did not take up any more storage like the May 2020 security update did but this also included the bug fixes too since I waited to apply that optional update.. Why are these updates taking up so much room and how can I reclaim this room?? Is this going to keep happening every month when I do a security update?? And what will happen when I do the May 2020 feature update. Will it even be able to update without doing a clean install?? Will it eat up all my storage?? This should not since I don't think Windows 10 later editions take up much more room than the current edition version 1909. Can someone help me to understand what is going on?? I don't want to have to do a clean install for every feature update and hope that every month's security and bug fix updates don't eat up all my remaining storage space. I want to have at least 5 gb. free. I should not have to put much more on the computer but I still want as much free room as possible. The computer runs fine for what it is. It is using around 4 gb. of reserved storage. I know that Windows will automatically reclaim space when my storage gets low but I want to control this myself just in case I need the storage. There was an article somewhere on using the command line tool "dism" to turn on/off reserved storage but it does not work for me. Is this a newer feature for the May 2020 update?? I am on home version 1909. When I run disk cleanup it does find around 4 gb. of windows update files but it won't remove them, it just scans for a long time. When I then rerun disk cleanup it does not find any more windows update files to be removed. Is this a bug?? Also my Windows update tells me that my device is not ready for the May 2020 update and to do nothing. It will appear later on. How is this done?? Is it done through an regular update first?? Do any drivers get updated through a regular update first without me having to do it myself. This is a main brand dell computer. John.

Why some unaccesible space is reserved in a storage?

Can I calculate this "pseudo space" in a fixed percentage? I mean, what about 500 GB and 1 TB drives? Is this scenerio same for SSDs?

Much like qubit said, for powers of 2, yes. But lately you are seeing SSD's with 120GB or 240 GB capacity, etc. They are automatically reserving the extra space, so a 240GB SSD now has the same storage space as one listed as 256. They've just set aside 16GB for wear levelling, etc.

Reserving disk space to keep Windows 10 up to date

Starting with the next major update we’re 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. Our 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 don’t need to set anything up—this process will automatically run in the background. The rest of this blog post will share additional details on how reserved storage can help optimize your device.

How does it work?

When apps and system processes create temporary files, these files will automatically be placed into reserved storage. These temporary files won’t 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 isn’t 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 it’s 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 that’s 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), we anticipate 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 we’ve reduced the size of Windows for most customers. We 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 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 aren’t using.

Follow these steps to check the reserved storage size: Click Start > Search for “Storage settings” > Click “Show more categories” > Click “System & reserved” > Look at the “Reserved storage” size.
