Space required to install Windows 10

If you’re looking to install Windows 10 on your computer or about to fresh Install Windows 10 but concerned how much space does Windows 10 take after install. This short guide will give you an estimated idea of whether you have recommended space to install and run windows 10 on your computer. Check the following points to decide whether you should install Windows 10 or not.

Windows 10 Install Size

Windows 10 receives two significant updates in a year. While the latest version works just fine on newer machines, old machines usually face issues when upgrading. To avoid all the mess created during the update process, we recommend that you clean install Windows 10 every 6 months.

Windows 10 Install size on Storage

A clean or fresh Window 10 installation size took 11.6 GB, though recommended free space is 16 GB for 32-bit OS and 20 GB for 64-bit OS, it is advisable to have a partition with more free space so that you can install more software and games. For this test we also installed Windows 10 on a partition which was 12GB in size and it occupied around 11.6GB leaving just 300MB.

^^ This will applies to you when Windows is installed on C:/ drive which is just 20GB.

Test 2 C:/ is 50GB+. Tested with: Windows 10 Nov 2019 update.

We installed Windows 10 on C:/ with 50GB+ Free Space and it took roughtly 25GB (24.4GB to b exact.

We also tested Windows 10 version 2004 (Pro edition 64-bit) on M.2 SSD it took similarly around 24.5GB and 25GB with Google Chrome installed.

At least 20+ GB will be used on your windows installation partition. But if a partition has near 20-30 GB and on storage limits, Windows 10 has a special feature** that will automatically compress some system files to keep working fine. But you can also do this manually, in rough figure this feature is likewise able to compress 5GB into 3GBb but that’s the limit. You can not compress everything in the windows directory.
** run Compact.exe /CompactOS:always in CMD to free up about 2GB space by compacting Windows file.

How big is windows 10 (ISO and system images)

A Windows 10 Pro edition would be around 3 to 5GB with standerd install.wim file.

  • x86 English Windows 10 ISO = 3.xx GB
  • x64 English Windows 10 ISO = 5.xx GB

Windows 10 Single language home edition saves a few MB in file size.

  • x86 Single Edition English Windows 10 ISO = 3.x GB
  • x64 Single Edition English Windows 10 ISO = 4.x GB

Though size may vary but not much. You can get official Windows 10 ISO using this guide. If you build a multi-edition ISO file it will take more space. For a single 32-bit + 64-bit the ISO will be around 3 to 5GB in space with compressed install.esd while install.wim file could be more than 5GB. ESD have better compression ratio but it takes longer to build one.

Windows 10 version 21H1

UUP files = 2.9 GB (x64) Download Windows 10 UUP files.

  • With standerd Install.WIM Size = 3.7GB
  • With compress Install.ESD Size = 2.7 GB
  • ISO with Install.esd = 3.35GB

Installing Windows 10 on SSD:

Roughly around the same as required on normal hard disks. As SSD (Solid-state drive) are faster so is windows 10 when you have an SSD. Having a solid-state drive will help the operating system to boot faster and work flawlessly. When tested on both ADATA SSD (C:/ 50GB) and M.2 Silicon power (C:/ 100GB) both were filled 20GB.

On the other hand, if there is suppose, C;/ is just 20GB then windows 10 manages to get installed in just 12 GB.

Installing from USB

Making a bootable USB from a Windows 10 ISO depends on its architecture. BTW a 4GB USB drive is enough for both 32-bit or 64-bit ISO. However, in case of multiple edition ISO, you may need at least 8GB USB drive.

Windows 10 Minimum Requirments.

Repeat this process to remove the rest unnecessary apps.

Hibernation in computing is to power down a computer while maintaining its state. If you have enabled Hibernation Mode in Windows, by changing the Folder Options to 'Show hidden files, folders and drives' and unchecking 'Hide protected operating system files (Recommended)', you will find a file named 'hiberfil.sys' located in the C drive, taking several gigabytes' storage space.

To free up disk space taken by this file, you can open CMD and run this command:
