Windows 10 Cloud hacked to run Win32 programs

That did not take long! Windows 10 Cloud has not been revealed officially yet, but someone managed to hack the operating system already to run legacy Win32 programs on it.

Windows 10 Cloud leaked earlier this month, and first impressions revealed that it looked like a revival of Microsoft's -- failed -- Windows RT operating system.

Windows RT was released alongside Windows 8 as a low cost solution. Microsoft's marketing back then did a bad job at highlighting to customers that Windows RT would not run Win32 programs-

Windows 10 Cloud looked to be in the same boat initially when the first ISO of it leaked on the Internet. It was revealed then however that users can upgrade the operating system to Windows 10 Pro, and that Windows 10 Cloud may be free.

Note: Microsoft has not confirmed any of this yet. It is possible that things may change along the way.

The leaked version of Windows 10 Cloud supports Windows Store apps and legacy Win32 programs that Microsoft whitelisted. Any Win32 program not on that list, and there are several that ship with Windows 10 Cloud that don't, won't run by default but will throw an error message instead:

The app you're trying to install isn't designed for Windows Cloud. Windows Cloud helps protect your PC by running on Windows Store apps.

Still want to install the app? See How.

The last sentence of the notification that users see when they try to run programs that are not whitelisted provides them with an option to upgrade the operating system to Windows 10 Pro.

This highlights one of the major difference to Windows RT, which did not ship with such an option. The upgrade option, and the fact that Windows 10 Cloud runs on x86 processors indicated strongly that Microsoft must have implemented a software restriction that prevents legacy Win32 programs from running on the operating system.

Jürgen Born suspects that Device Guard is used in Windows 10 Cloud to allow or block applications and programs based on signatures.

A Twitter user by the name of Longhorn posted a screenshot yesterday that showed Google Chrome and the Desktop App Converter running on a Windows 10 Cloud machine.

He managed to hack the restrictions of Windows 10 Cloud to run Google Chrome and the Desktop App Converter on a Windows 10 Cloud device.

The user did not reveal how it was done.

Information about the protection and how to circumvent it were published on the user's blog.

At the end, Windows Cloud is nothing more or less than a Professional variant with UMCI enforced.

At the end, Windows Cloud is nothing more or less than a Professional variant with UMCI enforced.

As such, its compatibility with existing Windows software* is only and solely prevented by having UMCI enabled and active.

While command, powershell, regedit and other core Windows features that give users control over the operating system are blocked, Linux Bash is not apparently. This allowed him to enable test signing of programs, and run a handful of other commands to get the legacy Win32 programs to run on Windows 10 Cloud

Provided that the screenshot is not fake, it shows that the built-in protection is not as protective as Microsoft would hope it to be. Microsoft has not announced Windows Cloud officially yet. Considering that it is still in development, it can be that Bash support will be dropped in future builds.

Since the methods used to get Chrome and the Desktop App Converter to run were not revealed, we don't know how complex of an operation the hack is.

Now You: Would you get Windows 10 Cloud if it was free?

    What mental age of reader are you targeting with the first sentence? 10?

    Why not write an article on how to *avoid* upgrading from W10 to W11. Analogous to those like me who avoided upgrading from 7 to 10 for as long as possible.

    If your paymaster Microsoft permits it, of course.

      I used Rufus to create an installer for a 6th gen intel i5 that had MBR. It upgraded using Setup. No issues except for Win 11 always prompting me to replace my local account. Still using Win 10 Pro on all my other PCs to avoid the bullying.

    bit pointless to upgrade for the sake of upgrading as you never know when you’ll get locked out because ms might suddenly not provide updates to unsupported systems.

    ps…. time travelling?

    Anyone willing to downgrade to this awful OS must like inflicting themselves with harm.

    I have become convinced now that anybody who has no qualms with using Windows 11/10 must fit into one of the following brackets:

    1) Too young to remember a time before W10 and W11 (doesn’t know better)

    2) Wants to play the latest games on their PC above anything else (or deeply needs some software which already dropped W7 support)

    3) Doesn’t know too much about how computers work, worried that they’d be absolutely lost and in trouble without the “”latest security””

    4) Microsoft apologist that tries to justify that the latest “features” and “changes” are actually a good thing, that improve Windows

    5) Uses their computer to do a bare minimum of like 3 different things, browse web, check emails, etc, so really doesn’t fuss

    Obviously that doesn’t cover everyone, there’s also the category that:

    6) Actually liked W7 more than 10, and held out as long as possible before switching, begrudgingly uses 10 now

    Have I missed any group off this list?

      You have missed in this group just about any professional user that uses business software like CAD programs or ERP Programs which are 99% of all professional users from this list.

      Linux doesn’t help anyone who is not a linux kid and apple is just a fancy facebook machine.

    1. This update is labaled as PREVIEW if it causes issues to unintelligent people, then they shouldn’t have allowed Preview updates ot install.

    2. I have installed it in a 11 years old computer, and no problems at all.

    3. Making a big drama over a bluescreen for an updated labeled as preview is ridiculous.

    This is probably another BS internet drama where people ran programs and scripts that modified the registry until they broke Windows, just for removing stuff that they weren’t even using just for the sake of it.
    Maybe people should stop playing geeks and actually either use Windows 10 or Windows 11, but don’t try to modify things just for the sake of it.

    Sometimes removing or stopping things (like defender is a perfect example) only need intelligence, not scripts or 3rd party programs that might mess with windows.

    Windows 11 was a pointless release, it was just created because some of the Windows team wanted to boost sales with some sort of new and improved Windows 10. Instead, Microsoft cannot support one version well let alone two.

      Windows 11 is the worst ugly shame by Microsoft ever. They should release with every new W11 version a complete free version of Starallback inside just to make this sh** OS functionally again.

    While there may be changes or updates to the Windows 10 Store for Business and Education in the future, it is premature to conclude that it will be discontinued based solely on rumors.

    My advice, I left win 15 years ago. Now I’m a happy linux user (linuxmint) but there is Centos, Fedora, Ubuntu depending on your needs.
