Tip: If you want to make some change of your partitions, then you can try MiniTool Partition Wizard.

What Is Windows 10?

First, we need to understand some general knowledge of Windows 10. Windows 10, as a personal computer operating system, is part of the Windows NT family of operating systems and was released on July 2015.

One of the best features of Windows 10 is support for Universal Windows Platform apps, with significant improvements in system security, command line, multimedia and gaming. Windows 10 has made seven updates since its release on July 29, 2015, and this Windows 10 May 2019 update automatically retain 7GB of disk space to maintain system updates.

So how big is Windows 10? Actually, Windows 10 Version 1809 and Version 1903 take different space.

How Much Space Does Windows 10 Version 1809 Take?

How many GB does Windows 10 Version 1809 take up? Windows 10 from July 29, 2015 to version 1809 October 2, 2018 requires only 1 GB for 32-bit or 2 GB for 64-bit memory and 16 GB for 32-bit and 20 GB for 64-bit hard drive space. Windows 10 Version 1809 and the previous Windows 10 version mainly store the installation packages, folders, etc. that come with Windows 10, and only require Windows 10 to run normally.

How Much Space Does Windows 10 Version 1903 Take?

How much space does Windows 10 Version 1903 need to install? The 1903 version of Windows 10, which was updated in May this year, requires a minimum of 1GB for 32-bit or 2GB for 64-bit memory, 32GB for 64-bit or 32-bit hard drive space.

The dramatic increase in Windows 10 space requirement is related to changes to the Windows update process. So how much space does Windows 10 take on an SSD? Previously, only when there was enough space on the system disk, Windows could download the update, because the update requires downloading a large number of files to be installed locally.

Some users who are not willing to update the system disk will just leave a little free space, but Windows 10 Version 1903 will reserve 7 GB of disk space and use temporary files to fill the disk to reserve space updates when there is no need to update.

But users can only activate the new installation or purchase a new device with Windows 10 Version 1903 installed to obtain the Reserved Storage function. Once installed, they cannot be deleted. However, if you just upgrade to Windows 10 automatically through Windows Update, you will not be able to get reserved storage.

The principle of automatically retaining 7GB of disk space:

Microsoft said that this feature will operate with the storage awareness of Windows 10, which is used to determine how much space the system has left.

Then the system starts to fill with temporary files according to the amount of remaining space. When the user deletes other files, the system uses the temporary files for the placeholder.

Stop the placeholder when the temporary file occupancy reaches 7GB. If the automatic update is needed, the system will automatically release the temporary file. Then user downloads the latest update, etc.

Retaining 7GB of disk space on Windows 10 may not cause problems for most desktop users, but it is a hassle for users with limited storage space.
