Parallels Desktop lets you run Windows applications on a Mac inside a virtual machine without replacing macOS or restarting the computer every time you switch systems.
The installation method depends on the Mac’s processor. Apple silicon Macs use Windows 11 on Arm, while Intel-based Macs can use compatible x64 Windows installation media. Check your Mac model before downloading Windows.
A Parallels Desktop license and a Windows license are separate products. Make sure the Windows edition covered by your product key matches the edition installed inside the virtual machine.
Before Installing Windows with Parallels
Check Whether Your Mac Uses Intel or Apple Silicon
Open the Apple menu and select About This Mac. Look for either a Processor entry identifying an Intel processor or a Chip entry identifying an Apple M-series chip.
| Mac Type | Windows Architecture | Recommended Installation Path |
|---|---|---|
| Apple silicon Mac | Windows 11 on Arm | Use Parallels’ built-in Windows 11 download and installation process. |
| Intel-based Mac | Compatible x64 Windows edition | Use a compatible Windows ISO file or other supported installation media. |
Prepare Parallels and a Valid Windows License
Install a current Parallels Desktop release that supports your macOS version and Mac hardware. You will also need administrator access, a stable internet connection, sufficient storage, and enough memory to run macOS and Windows together.
A Parallels license does not activate Windows. Purchase a separate Windows license matching the edition you plan to install. For basic home applications, a Windows 11 Home key may be sufficient.
Install Windows on an Apple Silicon Mac
Install Parallels Desktop
Download the current Parallels Desktop installer, open the downloaded DMG file, and follow the setup instructions. Grant only the macOS permissions required for the features you intend to use.
Open Parallels Desktop after installation and sign in or enter the Parallels license when requested.
Download and Install Windows 11 on Arm
If no virtual machines exist, Parallels normally displays an Install Windows option automatically.
If another virtual machine already exists, open the Parallels Control Center, select the plus button, choose Get Windows 11 from Microsoft, and continue with the installation.
Parallels downloads the correct Windows 11 on Arm image and creates the virtual machine. Accept Microsoft’s license terms when prompted.
Configure the Virtual Machine
Give the virtual machine a descriptive name and review the proposed processor, memory, storage, and sharing settings. Avoid assigning all available Mac resources to Windows because macOS must continue running at the same time.
Some Windows applications, games, drivers, and virtualization tools may not work in Windows 11 on Arm. Check application compatibility before relying on the virtual machine for specialist software.
Install Windows on an Intel Mac
The following screenshots show an older Parallels interface. Button names and layouts may differ in current releases, but the installation sequence remains broadly similar.
Create a New Virtual Machine
Open Parallels Desktop, select File > New, and choose the option to install Windows or another operating system from a DVD or image file.
Choose the Installation Media
Parallels may detect a compatible Windows ISO automatically. If it does not, select the option to locate the installation file manually.
Select the location containing the Windows installer. This will normally be an ISO image file downloaded from Microsoft, although supported DVD or USB installation media may also be available on compatible Intel Macs.
Enter the Windows Product Key
Enter the 25-character Windows product key when requested. The key is normally provided in the purchase confirmation email or product documentation.
Keep Express Installation enabled if you want Parallels to automate Windows setup and install Parallels Tools afterward.
Select How You Want to Use Windows
Select the profile that best matches your work, such as productivity, gaming, design, software development, or testing. Parallels uses this selection to propose suitable virtual hardware settings.
Choose the Virtual Machine Name and Location
Give the virtual machine a clear name and select where its files will be stored. Virtual machines can consume considerable disk space, so choose a location with enough free storage.
Review the option to share the virtual machine with other Mac users. Enable it only when other local accounts genuinely need access.
Start the Windows Installation
Review the settings and select Continue. Parallels will create the virtual machine and start Windows Setup. Follow the on-screen instructions without closing Parallels or interrupting the computer.
After setup completes, launch Windows from the Parallels Control Center or use the virtual machine’s power button.
Install Parallels Tools and Configure Integration
After Windows setup finishes, install or update Parallels Tools. These tools improve display scaling, mouse behavior, clipboard support, shared folders, networking, and overall virtual machine performance.
Restart Windows after Parallels Tools finishes installing. Review sharing and privacy settings before exposing Mac folders, applications, cameras, microphones, or clipboard contents to the Windows virtual machine.
Activate Windows and Check Compatibility
Inside the virtual machine, open Windows Activation settings and enter a valid product key for the installed edition. A Windows Home key will not activate Windows Pro, and a Pro key will not change an incorrectly installed edition automatically in every scenario.
Check that critical applications support the architecture used by the virtual machine. This is particularly important on Apple silicon, where Windows 11 on Arm may not support certain drivers, games, security tools, or applications requiring nested virtualization.
Performance, Storage, and Security
Balance system resources
Assign enough processors and memory for Windows without starving macOS. Start with Parallels’ recommended settings and increase resources only when measurements show a need.
Monitor storage
Windows updates, applications, snapshots, and temporary files can make the virtual machine grow substantially. Keep free space available on the Mac.
Create backups
Include important virtual machine data in a reliable backup plan. Avoid treating snapshots as a replacement for independent backups.
Protect Windows
Keep Windows and applications updated. A Windows virtual machine can still be affected by malware, unsafe downloads, and compromised accounts.
If you mainly need Word, Excel, and Outlook, Office 2024 Home & Business for Mac may let you work directly in macOS without maintaining a Windows virtual machine.
Frequently Asked Questions
Does Parallels include a Windows license?
No. Parallels Desktop and Windows are separate products. You need a valid Parallels license and a separate Windows license.
Which Windows version works on Apple silicon?
Apple M-series Macs use Windows 11 on Arm through a supported current version of Parallels Desktop.
Can an Intel Mac use a Windows ISO file?
Yes. An Intel-based Mac can create a Parallels virtual machine from a compatible x64 Windows ISO file.
Can I install Windows 10 on an Apple silicon Mac?
The current supported path on Apple silicon is Windows 11 on Arm. Windows 10 on Arm is not the recommended supported installation path for M-series Macs.
Will every Windows application work?
No. Compatibility depends on the Mac processor, Windows architecture, application, drivers, graphics requirements, and whether the software supports virtualization.
How much storage should I assign to Windows?
Use at least the amount required by Windows, Parallels, and your applications, with additional free space for updates and temporary files. The appropriate amount depends on your workload.
Conclusion
Parallels Desktop provides a practical way to run Windows alongside macOS, but the correct installation method depends on the Mac’s processor. Apple silicon users should install Windows 11 on Arm through Parallels, while Intel Mac users can create a virtual machine from compatible x64 installation media.
After installation, activate Windows, install Parallels Tools, review sharing permissions, and verify that important applications support the virtual machine’s architecture.
