Windows Microsoft has made Windows 8's final release available to MSDN and TechNet subscribers, so if you are one of those - have fun. The 90-day trial has also been released, so us mere mortals can have a go at it as well. The evaluation version is Windows 8 Enterprise, so it contains a number of features regular users normally won't see. As far as I can tell - it's a bit unclear - the trial version cannot be upgraded to a final version a few months down the line. Happy testing!

PAE is enforced as many companies still have to work with 16bit PLC devices with correspongind software and the 64bit systems does not support that. So this is just a way to enforce that the drivers are compatible with PAE. You might say that dosbox or some virtualization might do the trick, and indeed in some cases it will, but some devices and industrial hardware indeed need direct contact.

It is not only about the ram size, but also about the exact placement of registers available with old un-updated software (Siemens, i hate you for being the biggest culprit in this) in direct access to the named industrial hardware. In PAE 32+extra bits the initial bits for the conventional memory is in the same place, in a x64bit system this is not always the case.

Have a lovely day.

Thanks for the information - I'm really suprised that they don't have a custom system from the ground up with custom hardware where as what it seems is a hodge-podge of off the hardware with a butchered installation of Windows ;)

The cost savings from this approach are enormous.

Besides, hardware companies are rarely good at writing software. The "butchered installation of Windows" might actually be better than whatever they'll come up with.
