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.

With

an old Desktop machine with Intel® Xeon® Processor E3110 with clock speed of 3.0GHz

and a new server with AMD Opteron(TM) Processor 6272 with clock speed of 2.1GHz

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…
