Parallels Desktop Windows 10 Technical Preview

Our own Jeff Benjamin showed you earlier how anyone can try Windows 10 Technical Preview on their Mac for free, using VMware Fusion.

But if you use Parallels’ award-winning virtualization software, you must check out its most recent update.

Announced today, it enables experimental support for running both Office 10 and Windows 10 previews on your Mac.

The latest release of Parallels Desktop for Mac (10.1.4, build 28883), which can be downloaded from, is required for experimental support for Windows 10 Technical Preview (build 9926) and Office Preview for Windows 10 which includes Word, Excel and PowerPoint.

The included wizard will even download the Windows 10 Technical Preview directly from within Parallels Desktop and create a virtual machine for your copy of Windows 10 Technical Preview.

As we previously detailed, Windows 10 Technical Preview includes features like the new Start menu, Photos, Maps app, Cortana and Windows Store beta which offers Office Preview for Windows 10.

The software giant promised to make Windows 10 a free upgrade from Windows 8.1, Windows Phone 8.1 and Windows 7, “for the first year after Windows 10 is available.”

Shown on the top screenshot: Windows 10 Technology Preview and Word Preview for Windows 10 running in Parallels Desktop 10 on a Mac running OS X Yosemite.

And here’s Jeff’s video walkthrough about installing Windows 10 Technical Preview using the free VMware Fusion virtualization software.

In addition to running Windows 10 Technology Preview alongside OS X using free virtualization software like Oracle’s VM VirtualBox and the aforementioned VMWare Fusion, or paid ones with more features like Parallels Desktop, you can now try out Office for Windows 10 yourself.

According to a post on Microsoft’s Office Blog, folks signed up for the Windows 10 Technical Preview can download the universal Word, Powerpoint and Excel apps from the Windows Store Beta, with the universal editions of Outlook and Calendar expected at a later date.

Like in iOS, universal Windows apps combine in a single binary the code and assets needed to render its user interface properly across variously sized screens, ranging from touch-friendly smartphones and tablets to desktop computers.

With Parallels Desktop, you can run OS X and various operating systems side-by-side on your Mac. While this results in a slower performance versus dual-booting, virtualization gives you the flexibility to choose whichever operating systems best fits your needs, be it OS X Yosemite / Mavericks / Mountain Lion, Chrome OS, Android, Windows 8 or 7 or one of the many flavors of Linux.

The app costs $80, or $40 if you’re a student. A free two-week trial is available.

    Been running Windows 10 on a previous build of Parallels 10. Not sure why they say this is “required” but it may help I guess.

    • Chris Wagers

      I’ve been doing the same thing with no issues for at least a month and a half.

      • Carlos Medina

        Whats better VMWare or Parallel?

      • n0m0n

        I also am new to all this and was wondering the same thing.
        I’m going back and forth between VMWare or Parallel?
        Someone shared that I should install Boot Camp on my iMAC with a version of Win7 I have because I cant install a Win10 Tech Preview download, it has to be a disc version of Windows.
        I was told to then install either VMWare or Parallel.
        This way I can boot up either OS with dedicated resources, or have the ability to have windows within the OSX environment but they would share resources.

        Again I’m new to this and trying to learn this with out messing up my iMAC.

        So which and why would you recommend in your experienced positions?

        Yea i was reading your questions in Cult of Mac article about USB SSD lol.

        Essentiall VMWare and Parallel is just a virtual machine that can be ran alongside the Mac OS. Meaning that you can be in the Mac OS and run windows, well in a window lol. Meanwhile Bootcamp is basically booting up to the Windows OS rather then the Mac OS but boot camp virtualizes the process and takes full advantage of memory and all the hardware. Pretty much having windows.

        The difference between Parallel and VMWare versus Bootcamp is that VMWare and Parallel doesn’t use up as much of the resources because the Mac OS is also using it which limits the speed of it meanwhile Bootcamp take full advantage of the hardware thus making it more natively and faster.

        Essentially theeyre all the same but the way they are used is different. On two of them (VMWare and Parallel) you can use them alongside the MAC os while the other (Bootcamp) replaces the Mac os with windows until you restart your computer and switch over to the Mac OS.

        OK thanks
        So Im trying to rap my arms around this so I was planning on installing Boot Camp then Win 7 on a SSD but I think I may not totally understand what goes where.
        Im think I need to install BC and Win 7 on my iMAC and not a SSD (which I would still have to get).

        After that I can use the downloaded file (Win10) as a upgrade, followed by installing either Parallel or VMWare (I still would like to know which is preferred and why).

        Preferably as I shared in the Cult of MAC post I was interested in getting a SSD and installing everything on it but I don’t think I clearly understand how this all works very what Id like to do, which is not mess up my iMAC which is working GREAT.


        Thank you again

      • Carlos Medina

        You don’t need an SSD for BC. BC can use your internal SSD. The only time you’ll need an external SSD is if you want to install the windows partition on there but other then that its not necessarily needed. If you need help you can always youtube a tutorial or explanation to see what happens between VMWare, Parallel, and bootcamp.

  • n0m0n

    Another question I now plan to install Boot Camp (first) then a Win 7 Pro Disc I have. Because I also would like the capability to run both OS’s at once too I will probably install Parallel.
    In this post it says that Parallel will download Win 10 Technical Preview from within Parallel will that precent a problem since I have Win 7 installed via Boot Camp?


  • n0m0n

    OK After reading trying to understand all my options I would like to install Win 10 onto a 240gb USB SSD stick that I just received via both Boot Camp and Parallel so that I have the ability to use just Win10 or switch back and forth.
    As I shared I have been trying to grasp all this and think I’ve read, asked, so many questions I am now spinning.
    So what I should do first, I’ve downloaded Win10 Technical Preview file to my iMAC HD, wis it better to first install Win10 onto the SSD via Boot Camp or Parallel?
    I remember being told that Win10 wont install because its a downloaded file so I need to install Win8 first?

    I hope to get this done today (hopefully)

    THANK YOU ALL for any and all support offered.
    What a learning experience!
