Windows versions

Posted on Updated on

As you all know, many versions and editions of Windows were developed and released over time. After a while it could be useful to have a list by hand that can give you a quick overview of those versions and editions. Below you find a table that lists every main Windows version. With “main” I don’t mean the most important versions; what I do mean, is I only list the distinct versions at “the highest versioning level”, but no sub-versions (versions that fall under the main version). For example, Windows 7 is listed, but I won’t talk about Windows 7 SP1 or some small update for Windows 7. Later on though I’ll mention one “smaller” update anyway, because it’s quite special, in the sense that it’s almost considered to be a main version, although officially it isn’t. Note I’m only dealing with “normal/classic” client and server flavors here, so I’m not talking about Windows Mobile, Windows Phone, Windows Embedded, etc. Read the rest of this entry »

Windows 8, Windows Server 2012 and many others: a complete and updated overview of their releases and related aspects

Posted on Updated on

The last couple of days were quite busy: several Windows 8 SKUs, Windows Server 2012 SKUs and other products (like Visual Studio 2012 SKUs) have been released, while many others have been RTM’d (like Windows RT), gotten (new) public test releases (like Windows Server 2012 Essentials) and/or are expected to be released soon (like Windows Phone 8 SDK). I’ve already written 2 articles about it:

Now that we are a few more days full of news/releases/… further, things have become more clear and I’ve found a little bit more time, I thought it was time to write another article which is more complete and updated. So with the start of this new article my previous blog posts are already outdated and not-so-complete anymore. J Read the rest of this entry »

Windows 8 released

Posted on Updated on

UPDATE: there is a new blog post which is more complete and updated. Check out https://windoh.wordpress.com/2012/08/26/windows-8-windows-server-2012-and-many-others-a-complete-and-updated-overview-of-their-releases-and-related-aspects.

On the 15th of August 2012 Windows 8 has been officially released, although only to a limited audience, i.e. MSDN and TechNet subscribers. Through TechNet 24 SKUs are available, while this is 36 at MSDN (the same 24 + 12 checked builds, used for debugging and typically only useful for a small group of developers).

The release isn’t exactly a surprise, as it was announced about 2 weeks ago. As you probably know Windows 8 and other products were RTM’d on the 1st of August 2012. It was also officially announced Volume License customers with Software Assurance (SA) may expect Windows 8 on the 16th of August 2012 UPDATE: through the Volume Licensing Service Center (VLSC) site. Other programs follow later, with General Availability (GA) planned for the 26th of October 2012.

On the 1st of August 2012, Windows 8, Windows Server 2012 and Visual Studio 2012 were RTM’d. This was officially announced by Microsoft. Let’s take a look at what this all means. Before we dive into the recent details, let’s get a quick overview first of the Windows 8 ecosystem. This is quite important, because otherwise it’s difficult to get the full picture.

Nokia Lumia series officially announced for Belgium

Posted on Updated on

Today Nokia and Microsoft have officially announced the Nokia Lumia series for Belgium on a press conference. This evening Nokia has held an official Nokia event in Brussels (the Belgian capital) to celebrate the Lumia launch in Belgium. The Lumia series is Nokia’s series for Windows Phone (WP) smartphones. As you probably know, Nokia has made a partnership with Microsoft in 2011 to move as much as possible to the Windows Phone platform and give other operating systems (like their Symbian and MeeGo) a much lower priority. As time evolves, Nokia will prioritize Windows Phone more and more. At the end of last year the first Lumia smartphones arrived. The first Lumia, released in November 2011, was the high-end Lumia 800, while a few weeks later the middle-end Lumia 710 was introduced. Read the rest of this entry »

The Windows memory architecture – part 1: the basics

Posted on Updated on

Most IT professionals dealing with Windows in a decent way have already heard of terms like “virtual memory”, “physical memory”, “working set”, “reserving memory”, “committed memory”, “page file”, “swapping”, “regions”, etc. I can imagine that most of them don’t really know what this is all about. Okay, the difference between physical and virtual memory and the meaning of a page file are probably quite understood, but is everybody really knowing what they are talking about? Do they really know, for instance, what a page file is for, how it is organized, how it is used, how the system behaves if it exists (or doesn’t exist),…? I seriously have my doubts. And I’m sure that those other dirty words like “working set”, “committed memory” and “data alignment” were, are and will be ignored when met. Well, it shouldn’t be like this: understanding how memory works, especially at the OS level, is important, whether you are a system administrator/engineer/architect, a developer or another kind of IT pro. You can improve performance, fine-tune applications and systems, troubleshoot so much easier and faster and control your environment so much better if you understand how this key part of your machine works and behaves. And it shouldn’t be that difficult: read, learn and, yes, have a better life (no, I promise you it won’t be the opposite!). Read the rest of this entry »
