Microsoft announced that it has completed work on its Desktop Bridge, which is a software utility designed to port applications from older versions of Windows to Windows 10. Although the Desktop Bridge has several important features, it may negatively impact software performance overall.

  • Move to Windows 10 and lose all other Windows platforms. This is Microsoft attempt to save Windows Store for failure in other words who needs UWP garbage?

    So I may have missed it ...can you take existing, older windows programs and make them work on Windows 10? I'm talking binaries now, not source code and then a rebuild.

    You do realise that win32 applications are kinda outdated... at some point you have to evolve even if you piss off people who want compatibility from DOS 6.22 to Windows 10.

    I don`t see the Store as a failure at all. Imagine the mobile world without a Store just like PCs are now, having to google "best fps game android" and then find millions of websites claming the best, without any real user reviews and tons of websites with adds on them with several Download buttons that run silent installers on your Phone.

    That`s old and outdated, the Store is the way to go, the only issues here are that people like Tim Sweeney from EPIC games are shouting that MS wants to block Steam and that they want a monopoly... well at this point Steam is kinda a monopoly and he`s just fine with that .. we have Origin and UPlay but those are almost non-existent.

    The real grudge is the % that MS gets from each sale on their Store, and people who pirate games / applications, from my knowledge Windows has the power to disable apps that are part from the Store but are pirated.

  • Win32 is not outdated. UWP doesn't offer a squat in performance and feature wise. This whole converter is just repackaging Win32 and it has nothing to do with concept of UWP in other words only reason for it is for MS to save Windows Store, seems no one cares about.

    "For the first time, you will be able to use the Linux Bash command on Windows."

    Patently false. Bash has been available on Windows via Cygwin since 1996.

    Win32 can only on an OS level address 4 gigs of memory (shared with the video card), with a single program able to use 1.75 gig of it at most. The only way around this is through Physical Addressing Extensions which is a software hack that swaps out pages of memory at a time inside the 4 gig limit. This applies to the OS only as apps still have to stay within that 1.75 gig limit.

    32 bit programs ran on 64 bit versions of windows run through an emulator called 'wow64'. This was the same kind of thing Microsoft had to do back in the days when they used to support 16 bit programs during their switch to Windows 95 (which was 32 bit). To run anything through an emulator will always provide some form of performance penalty; even minor.

    Win32 applications at this point are most definitely outdated; especially vs their Win64 counterparts.


    As with UWP, the idea behind that is to create a unified environment (API) where the underlying hardware no longer matters (much like java). The biggest advantage I can see to this is that an Win32 app can be easily converted to run on other devices; including ARM based ones (tablets, phones, etc). The obvious disadvantage though is the performance hit due to non optimization/specialization; which the article already addresses. This may not be their smartest move as the only other OS setup like this, Android, runs like garbage for apps that rely on real-time metrics.

    Windows 10 automatically installed on my computer without my permission. It has compromise my system because come to find out my computer is not compatible with Win10. I am looking for a class action law suit to join. Anyone with any thoughts woul be helpful.

    ...

    The memory limits and PAE stuff you mention only apply to 32 bit Windows. 32 bit programs running on 64 bit Windows are able to make use of up to 4 GB.

    I've seen Win32 used to refer to the Windows API in general regardless of if the program is actually 32 bit or 64 bit, so the distinctions you make between Win32 and Win64 are not necessarily relevant and Win32/the Windows API is not outdated.

    WoW64 is not an emulator (unless you're on an Itanium version of Windows), it is a lightweight compatibility layer that switches the CPU between 32 and 64 bit modes. So instead of converting all the instructions to run on a 64 bit CPU, it just tells the CPU to use the 32 bit instructions natively.

    Yeah, and I've been using it since about then. If/when I run Win10, I'll try installing the Ubuntu/Windows packages as an alternative to Cygwin/X, but I wouldn't be surprised to find myself sticking with what works.

    I just wish Cygwin's installer & package management were better. And that the runtime libraries weren't GPL'd (LGPL would be fine, but GPL means you cannot link Cygwin libraries from binary-only commercial products).
