I was looking for a way to determine the version of the operating system my program was running under. When I Googled it, I got a lot of code hits, but they all had the same problem: They were not updated for Windows 7. So I decided to simply amend that code and add the things that were missing. The class I came up with is very easy to use.
As mentioned, I found a lot of suggestions to how this could be detected, but none of them worked properly. But this doesn't actually return the Bit architecture of the OS, it returns the bit value for the running program.
So for programs running in 32 bit mode on 64 bit Windows, the above code will return This is actually very misleading, because the result of this is exactly the same as version 1: It doesn't return the PROCESSOR bit architecture as the name says, but the bit architecture of the running program.
They can be found in the source code. Once again, I was disappointed. This code - despite the presence of the processor specific flags - ALSO returned the bits of the running program, not the OS and not the processor.
NOW I got another result. But alas, it seemed that this API actually returns the bit architecture of the processor itself. And I was interested in the OS bit architecture. You can easily have a 32 bit windows version running on a 64 bit processored machine.
If the program is running as 32 bits, then the code checks the process the code runs in to determine if that's 32 or 64 bits. If it is 64, then the OS will be 64 bits, but the program is running as 32 bits.
And if it's 32 then the OS is also 32 bits. In the end, I included most of these methods in the final class lib, because it can be nice to be able to distinguish between the bit architecture of the Program, the OS and the Processor. Thanks to Member , Scott Vickery for the Windows 8. Thanks to Brisingr Aerowing for help with the Windows 10 adaptation.

Also, all of them had the same two shortcomings: They didn't include all available Windows editions especially the absence of "Professional" bothered me as that is the operating system edition I normally use I wanted to know if the operating system was 32 bit or 64 bit, and none of the solutions I found correctly determined that.

По иронии судьбы в Третьем узле секреты не очень-то любили. Нареченный Детским манежем, Третий узел ничем не напоминал стерильную атмосферу остальной части шифровалки. Его обстановка напоминала домашнюю - мягкий ковер, высокотехнологичная звуковая система, холодильник, полный напитков и всяческой еды, маленькая кухня и даже баскетбольное кольцо.
В отношении шифровалки в АНБ сложилась своеобразная философия.
