How to Upgrade from 32-bit to 64-bit Version of Windows 10

Start64!Have you ever wondered why you have the 32-bit version of Windows 10 installed on your computer while you have all the requirements to install the new version? Maybe you even need to upgrade from the 32-bit to the 64-bit version of Windows since some of your memory is not used (the 32-bit version only supports up to 4Gb of RAM). Before you upgrade, you need to check some things out first.

Why it matters whether your Windows is 32-bit or 64-bit

Start64!I have to admit this isn’t something I’ve thought about in a long time, but I peeked around and lo and behold Microsoft’s latest OS—Windows 10—is being offered in a 32-bit version. Microsoft says it has at least 71 million 32-bit users still (as of 2014), and didn’t want to leave them out in the cold, or thrust them into the open arms of Cupertino (headquarters of rival Apple). Given this situation, I figured I’d explain the main difference between the two.

Do You Need More RAM To Run 32-Bit Programs On 64-Bit Windows?

Start64!Most computers today ship with a 64-bit version of Windows, and often a minimal amount of RAM. This brings into question how well these systems perform. This is especially true when users want to run their legacy 32-bit software on these new computers. This is especially true when users want to run their legacy 32-bit software on these new computers.

How to Switch From 32-bit Windows 10 to 64-bit Windows 10

Start64!Microsoft gives you the 32-bit version of Windows 10 if you upgrade from the 32-bit version of Windows 7 or 8.1. But you can switch to the 64-bit version, assuming your hardware supports it. If you had a 32-bit versions of Windows 7 or 8.1 installed on your PC and upgraded to Windows 10, Microsoft gave you the 32-bit version of Windows 10.

C++ Tail Recursion Using 64-bit variables

Start64!I want to share with you a problem I run into comparing iterative and recursive functions in C++. There are several differences between recursion and iteration, this article explains the topic nicely if you want to know more. In general languages like Java, C, and Python, recursion is fairly expensive compared to iteration because it requires the allocation of a new stack frame.

64-bit considerations with K2

Start64!We are often asked “I have a 64-bit Windows computer. Should I install 32-bit or 64-bit components?” Our recommendation is generally to install 64-bit components on a 64-bit OS. For KeyServer in particular though, there are a few reasons that would force you to use 32-bit components on a 64-bit OS though and we’ll cover these below.
