I’ve been writing a lot about Parallels Desktop<\/a><\/strong>, a powerful app for running virtual machines that now runs on Apple Silicon<\/strong> Macs. In April, a short article showed how to install both an ARM version of Windows 10 and Ubuntu Linux on an M1 Mac<\/a>. Today I’ll show you how to test the upcoming Microsoft Windows 11<\/strong> on an M1 Mac using a Parallels Desktop virtual machine.<\/p>\n\n\n\n

Are Windows Virtual Machines Living on Borrowed Time?<\/h2>\n\n\n\n

For Mac users who need to run Microsoft Windows on their computers for compatibility reasons, virtual machines are currently the only game in town. Just last week, Microsoft announced Windows 365<\/a><\/strong>, a way to run Windows and Windows apps in a web browser. While Windows 365 is initially targeting businesses starting August 2, 2021, the company may eventually bring the “Cloud PC” service to consumers. <\/p>\n\n\n\n

Word has it that Apple users can run Windows 365 on Mac and iPad. Will this make Windows virtual machines obsolete? Probably not. Windows 365 requires a full-time internet connection. For field workers using Macs a Parallels or UTM<\/a><\/strong> virtual machine is a necessity.<\/p>\n\n\n\n

Microsoft Windows 11<\/h2>\n\n\n\n

The next version of Windows is expected to ship in October of 2021. For system administrators who might need to test compatibility of the new operating system with existing applications and for curious consumers, Microsoft made a preview of Windows 11 available to those who are in the Windows Insider program<\/a><\/strong>. <\/p>\n\n\n\n

Almost immediately, a number of Mac users attempted to run the ARM64 version of Microsoft Windows 11 under Parallels Desktop on M1 Macs. Most ran into the same barrier — a message during installation stating that their computer wasn’t compatible. In each case, the error had to do with the Mac not supporting TPM 2.0. That’s “Trusted Platform Module”, used for digital rights management, Windows Defender, and more.<\/p>\n\n\n\n

Fortunately, there’s a workaround. In the remainder of this post, I’ll show you how to install Windows 11 on your M1 Mac running Parallels Desktop. <\/p>\n\n\n\n

\n\n\n\n

Start with a Clean Windows 10 Virtual Machine<\/h2>\n\n\n\n

I wanted to keep my Windows 10 virtual machine, so rather than upgrade the existing VM to Windows 11, I created a totally Parallels Windows 10 VM and renamed it to Windows 11. Fortunately, that’s a fast process. <\/p>\n\n\n\n

You’ll need to be a member of the Microsoft Insider program. If you aren’t, use the link in the previous section to sign up, then download the VHDX file used for installation<\/a>. Unlike in our experiment with UTM, there’s no need to convert the VHDX file to a new format prior to creating the Parallels virtual machine. <\/p>\n\n\n\n

After the clean Windows 10 VM is running, shut it down. Click the “gear” icon on the Parallels Control Center listing for your new virtual machine and make sure the hardware configuration matches this:<\/p>\n\n\n\n

\"Give<\/a>
Give the “clean” VM at least 8 GB of memory and a name to indicate Windows 11<\/figcaption><\/figure><\/div>\n\n\n\n

Once the configuration has been updated, close settings and power up the virtual machine again.<\/p>\n\n\n\n

\n\n\n\n

Remember RegEdit?<\/h2>\n\n\n\n

Anyone who has been a serious user of Windows for any length of time knows about RegEdit — the registry editor for Windows. It’s used to edit individual settings in a dynamic link library (dll) containing common code for the operating system or apps. <\/p>\n\n\n\n

The workaround that allows us to upgrade our Windows 10 VM to Windows 11 uses RegEdit to change some settings that let Windows Update know that it is OK to install the Windows 11 preview. Here are the steps to take:<\/p>\n\n\n\n

  1. Launch RegEdit. If you’re unsure where it is, click on the Search button (looks like a magnifying glass), type in RegEdit, and press return. The app launches:<\/li><\/ol>\n\n\n\n
    \"Using<\/a>

    2. You’ll need to navigate to HKEY_LOCAL_MACHINE\\SOFTWARE\\Microsoft\\WindowsSelfHost. Click Applicability. Right-click BranchName and change the value data to Dev. Click OK to save the edited string.<\/p>\n\n\n\n

    3. Next, click UI (same path as above). Under UI, click Selection. Right-click BranchHome and change the value data to Dev. Once again, click OK to save the edited string.<\/p>\n\n\n\n

    4. Close RegEdit, then restart the virtual machine.<\/p>\n\n\n\n

    \n\n\n\n

    Windows Update<\/h2>\n\n\n\n

    When the virtual machine is restarted, go to the Start Menu and click Settings. In Settings, click Update & Security. Windows 11 should appear as an update:<\/p>\n\n\n\n

    \"Windows<\/a>

    Click “Fix Issues”, and the download begins. When the download gets to about 8%, the installer stops with the error message “This PC Can’t Run Windows 11”. That’s the TPM issue described earlier. Of course, some wise person came up with a workaround…<\/p>\n\n\n\n

    \n\n\n\n

    The TPM Workaround for Microsoft Windows 11<\/h2>\n\n\n\n
    1. Launch File Explorer and open the C: drive:<\/li><\/ol>\n\n\n\n
      \"Searching<\/a>

      2. When the file is found (see below, it’s in a $WINDOWS.~BT hidden folder), right-click it and select “cut” from the menu.<\/p>\n\n\n\n

      \"The<\/a>
      The found AppraiserRes.dll file<\/figcaption><\/figure><\/div>\n\n\n\n

      3. Paste the file you just copied onto the desktop or into a blank folder on the desktop. Minimize the File Explorer window as you’ll need it again shortly.<\/p>\n\n\n\n

      4. Go back to Windows Update, and click Continue. It shows a screen that says “Setup is Cleaning Up”. <\/p>\n\n\n\n

      5. Eventually you’ll see that familiar Fix Issues button we saw earlier. Click it. This time, the download proceeds normally. Once it is past the 8 or 9% mark, open the File Explorer window again and copy and paste the AppraiserRes.dll file back into its original folder. You may need to enter your Windows admin password to allow this to happen.<\/p>\n\n\n\n

      6. Windows 11 installs quickly, then reboots. Windows Update may download a few updates after reboot, but that also happens quickly. <\/p>\n\n\n\n

      \n\n\n\n

      Enjoy Your Windows 11 Insider Preview<\/h2>\n\n\n\n

      At this point, you can try out the features of the Windows 11 Insider Preview. As with the Windows 10 ARM installation, I was surprised at how quickly Windows 11 runs in Parallels Desktop on an M1 Mac. The UI of Windows 11 is different — in a good way — from that of Windows 10. <\/p>\n\n\n\n

      You’ll see some features in Windows 11 Insider Preview that are similar to what we’ll be getting this fall in macOS Monterey, including desktop widgets. If anything, Windows 11 seems much more Mac-like than any previous version of Windows.<\/p>\n\n\n\n

      \n\n\n\n

      Remember…<\/h2>\n\n\n\n

      Remember that this is an Insider Preview of Windows 11 and is not meant to be a permanent installation. Eventually you’ll need to acquire an ARM-compatible version of Windows 11 to install in Parallels Desktop, or perhaps Windows 365 will finally be available. In the meantime, this is a great way to familiarize yourself with “that other” operating system. <\/p>\n\n\n\n
