If you’re trying to install Windows on your Mac, you’ll need to download a Windows 10 ISO image or Windows 11 VHDX file.

A Windows ISO image or VHDX file is a downloaded version of the operating system that you can use to install it on other machines including Macs.

Microsoft has finally standardized the process for this making it very easy to download an ISO for Windows 7, Windows 8.1, Windows 10 or a VHDX file for Windows 11 from the Microsoft Software Download site.

For Windows 10 and Windows 11, you don’t even need to have a license key to use it although if you do have one, entering it will allow you to customize Windows and remove a watermark at the bottom of the screen.

If you need to download a Windows ISO for Windows 7 or Windows 8.1, you’ll need a license key though.

What You’ll Need To Install Windows 11 on a Mac

At the moment, the best way to run Windows 11 on a Mac is via Parallels. This is because Windows 11 requires a TPM chip which does not exist in either Intel or M1 Macs.

However, Parallels can emulate a virtual TPM chip which allows you to install Windows 11 on both M1 Macs and Intel Macs.

The process for downloading Windows 11 on a Mac is slightly different however depending on whether you have an Intel Mac or an M1 Mac.

Here’s what you’ll need to make sure you have before you can install Windows 11 on your Mac:

  • An Intel or M1 chip Mac running macOS Big Sur or Monterey
  • A copy of Parallels which is the only virtual environment that can emulate the TPM chip required to install Windows 11 on a Mac.
  • You’ll need 64GB or more free storage space on your Mac startup disk. This is the bare minimum you’ll need but we strongly recommend at least 128GB of free storage space as automatic Windows updates will quickly eat up that space

The only alternative to this is to use Boot Camp to install Windows 11 on a Mac but this only works for Intel Macs. Boot Camp does not work with the latest Apple Silicon M1 Macs.

It also involves downloading a slightly modified version of the Windows 11 ISO which isn’t available from the Microsoft website.

How To Download Windows 11 For Free On An M1 Mac

If you’ve got an M1 Mac, you need to register for the Windows Insider Program and then download the VHDX image of the Insider Preview Windows 11 For ARM instead from Microsoft.

Note that it’s not yet possible to run the standard x86 version of Windows 11 on M1 Macs like you can on Intel Macs although it’s likely that Parallels will add support for this eventually.

Windows ARM is very similar the standard version of Windows but is compatible with less software as it only works with ARM (Advanced RISC Machine) chips.

This means that unfortunately many of your Windows applications may not work using Windows 11 on an M1 Mac unless they are ARM compatible.

What You’ll Need To Install Windows 10 on a Mac

Here’s what you’ll need to make sure you have before you can install Windows 10 on your Mac:

  • You’ll need 64GB or more free storage space on your Mac startup disk. This is the bare minimum you’ll need but we strongly recommend at least 128GB of free storage space as automatic Windows updates will quickly eat up that space.
  • iMac Pros or Mac Pros with 128GB of memory (RAM) or more will require at least as much free hard drive storage space as your Mac has memory.
  • A USB flash drive or external hard drive with at least 5GB space. You’ll need this to put the ISO image on so that your Mac can install Windows. However, if you have any of the following models of Mac running macOS El Capitan 10.11 or later, you don’t need an external device at all because your Mac can use the internal drive to temporarily store what you need to install Windows.
    • MacBook Pro (2015 and later)
    • MacBook Air (2015 and later)
    • MacBook (2015 and later)
    • iMac (2015 and later)
    • iMac Pro
    • Mac Pro (Late 2013)

How To Download Windows 10 For Free on Intel & M1 Macs

Unlike Windows 11, the process for downloading Windows 10 on a Mac is the same and you can run the standard x86 version of Windows 10 on an M1 Mac.

However, since Boot Camp only works on Intel Macs, you’ll need to follow these instructions to install Windows 10 on an M1 Mac.

How To Download A Windows 7 or 8.1 ISO On a Mac

You will need to have already purchased a copy of Windows 7 or 8.1 before you can do this and have the Windows Product Key ready.

If you purchased Windows online, you should receive the Product Key immediately via email so you don’t have to wait to for it to physically arrive in the post before you can do this.
