Why can’t Windows 7 be installed on a ARM processor based system?

Today I was reading some news(1, 2, 3, 4) about Microsoft Windows 8 and saw that one of the new features is that it can run over a ARM processor based system. This make me wondering the reasons that it cannot be done with the current release version of Windows(Seven).

What are the actual limitations to Windows 7 to be aware of…

Why have CPU manufacturers stopped increasing the clock speeds of their processors?

I have read that manufacturers stopped concentrating on higher clock speeds and are now working on other things to improve performance.

So really, what is the overhead of virtualization and when should I be concerned?

I’m searching for good rules of thumb to understand when NOT to virtualize a machine.

For example, I know that a fully CPU-bound process with near 100% utilization is probably not a good idea to virtualize, but is there any sense in running something which leverages the CPU most of the time a “substantial amount”…

Why doesn’t "add more cores" face the same physical limitations as "make the CPU faster"?

In 2014, I hear a lot of programming languages touted for their concurrency features. Concurrency is said to be crucial for performance gains.

In making this statement, many people point back to a 2005 article called The Free Lunch Is Over: A Fundamental Turn Toward Concurrency in Software. The basic…

How does Windows 2008 R2 run 32-bit applications?

If 32-bit processor support is disabled in Windows Server 2008 R2, how does the operating system run 32-bit programs?

Answer [by Malte Clasen]: How does Windows 2008 R2 run 32-bit applications?

x64 CPUs can actually run 32-bit (x86) code in parallel to 64-bit code. The WOW64 layer of Windows translates the system calls of 32-bit programs to the…
