How Much Space Does Windows 11 Take on Your Disk?

If you want to install this new version of Windows, your device should meet the basic system and hardware requirements for Windows 11. Among these requirements, you may have noticed this one - Storage: 64 GB or larger storage device.

How big is Windows 11? Does this mean the Windows 11 size is 64 GB? Of course, not. So far, no Windows operating system has taken up such a large space. This minimum disk space requirement is to better ensure the operation of Windows 11.

How many GB is Windows 11? It is not a fixed number.

How much space does Windows 11 take? Now, let’s see two cases.

Case 1: Clean Install Windows 11

Cleaning install Windows 11 will remove all files, settings, and apps on your computer. It only installs Windows 11 on your device. So, the storage usage of drive C after Windows 11 clean install is the closest to the Windows 11 size.

Recently, I have upgraded Windows 7 to Windows 11 Home via a clean install. Now, let’s have a look at the storage usage of drive C.

Go to Start > Settings > Storage > Show more categories to see the disk usage. Details are as follows:

storage usage after Windows 11 clean install

  • System & reserved: 18.0 GB
  • Apps & features: 2.78 GB
  • Temporary files: 326 MB
  • Other: 6.44 MB
  • OneDrive: 4.00 KB

The total size is about 21.1 GB.

However, this doesn’t mean that the Windows 11 install size is 21.1 GB. It is just one case. If you clean install Windows 11 Pro or Windows 11 Education on your computer, the situation will be different.

Now, let’s dig more:

System & reserved

You can click System & reserved to see the specific occupancy situations.

  • The system files: 8.18 GB
  • The reserved storage: 7.48 GB
  • The virtual memory: 1.93 GB
  • The hibernation file: 409 MB

How many GB is Windows 11 (clean install)?

Although it is not sure of the exact GB of Windows 11, there is a general statement: a fresh installation of Windows 11 will take up about 27 GB of space on drive C. Most of the files are system files and system reserved files. Besides, Windows pre-installed apps take up about 3 GB of space.

Case 2: Upgrade to Windows 11

I upgrade my other computer to Windows 11 via Windows Update. Now, let’s use the same way to check the space usage of the C drive.

Under Storage usage:

  • System & reserved: 36.0 GB
  • Apps & features: 22.5 GB
  • Temporary files: 4.11 GB
  • Other: 2.63 GB

How many GB is Windows 11 (upgrade to Windows 11 from Windows 10)?

You see the value of this situation is not indicative. The total size is even bigger than 64 GB. Many factors can impact the amount of free space on C drive for upgrading to Windows 11:

  • The Windows versions that were previously installed on your computer.
  • The free space available from Windows files to reuse, such as the virtual memory page files and hibernation file.
  • The apps that are installed on your machine.
  • How installed apps store data.

Sum up

The Windows 11 install size is not fixed. In general, a fresh Windows 11 install can take up about 27 GB of space on your disk. But why Microsoft requires more for Windows 11 upgrade?

The Windows 11 requirement on disk space of 64 GB is to ensure a successful upgrade. After upgrading, temporary files, regular Windows update files, system restore files, and more will eat up more space. So, there should be enough space on the system drive.
