How to fix error 80240016 while Upgrading to Windows 10

While upgrading to Windows 10, if you ever got the famous 80240016 Windows update error message saying that “Windows 10 couldn’t be installed” (as the screnshot below shows), don’t worry at all as it needs a small fix:1

All you need to do is to open Windows Defender by searching for it in Control Panel (on Windows 7) or in the start screen (on Windows 8/8.1) -> open the Settings tab -> uncheck “Turn on real-time protection (recommended)”

2

The rest is a piece of cake then. Just re-try the upgrade process and you will see it will never fail on you again:

If you still had issues upgrading to Windows 10, please let me know in the comments section and I will try my best to help you.

Ultimate Guide to Security on Windows Server 2012 R2

2

I am so proud and excited to announce that I am finally finished with my first book and it is released to public. This book is on the topic of security on Windows Server 2012 R2 and after a year of working on it, I finally decided to not release it through Microsoft global marketplace (which is only private to training centers worldwide) and instead self publish it and make it available to everyone globally.

Learn how to secure the new Microsoft Windows Server 2012 R2 through this completely practical book which includes many step-by-step guides, exercises, and lab scenarios. This book will:

  • Provide beginner to advanced level content on the topic of security
  • Include many step-by-step hands-on labs and exercises
  • Include guides on how to configure commonly-used security services such as Network Access Protection, Network Policy Services, Dynamic Access Control, and many more.
  • Include also contents on how to configure security for Hyper-V
  • Fit also the need of those managing Windows Server 2008 (R2) environments

This book is a must-read for those who are tired of searching for good contents and would like to read something which is so right to the point. You can have more information about this book from www.windowsserversecurity.com and even have a glance inside the book contents.

Looking forward to your feedback about the book.

Cheers,

Writting a book: My new adventure…

It’s been quite a long time I’ve been thinking of authoring a book as a new experience. In fact that’s been something I always wanted to do but was never able to make enough time for it. I think the situation is pretty much the same now when it comes to my time and schedule but finally I’ve made up my mind and I’d have to probably cut down the time I spend on my outdoor activities and put it more on this new adventure.

Well to be more specific about my book, recently I signed a contract with Microsoft and Arvato which is a third party company now taking care of Microsoft courseware library. Based on this contract I will write a complete course including a book and all the other course materials such as Powerpoint slides and etc. and Arvato works along with me through the authoring process. They are now hosting an online store for Microsoft selling all the different Microsoft Official Courses (MOC). Microsoft will also take care of all the marketing and promotion for the courses authors publish. To me it sounded like a great collaboration and I’d really want to go for it. That for sure is a great market since my book will be marketed all around the world and all the training centers located anywhere in the world will be able to purchase it.

Well, coming back to the main topic of this post which is the book, I want to author a complete course on Security in Windows Server 2012 from a complete technical point of view. I have not yet chosen a title for it but I am now working together with Microsoft on the modules and lessons to be included in the book. For the time being I cannot reveal any more secrets about it but hopefully in the very near future when I am on the track with writing, I will let you know more.

At the end I’d really love to know your thoughts on my book. What chapters and modules do you think I need to add to it? Do you have any specific topic in mind that you think has never been paid enough attention to in any other courses published so far by Microsoft? I’d be glad to know your feedback. You can also send me emails and share your thoughts with me.

Cheers

Talk to me about your interests…

Hey everyone…

I hope every one of you is doing great…

I was thinking to myself today about my blog and its visitors. You know over the past months and especially in the past three months, the number of my blog’s visitors has been doubled which is a really good thing and let’s not discuss the reasons… So today I just thought it might be a really good idea to ask you to talk to me more and give me your opinions on what you want me to write about…

Is there any specific security technology that you want me to write about?

Any specific post in my blog that you want me to extend?

Do you have any general comment about my posts that you think I should know?

Please let me know what you think in the comments because I would really love to hear from you… I have a lot of visitors every day on my blog but rarely do I hear from them. So that’s what I am doing… Yes, asking you to talk to me and let me know about what you think and want…

Please also feel free to subscribe to my blog or even directly contact me on e-mail. The more you show interest to talk to me, the more motivated I get and the more energy I have in writing…

Have a great weekend 🙂

Microsoft Baseline Security Analyzer 2.2

When it comes to security, once of the most important things is the operating system security. The client and server operating systems need to be fully patched and secure on a regular basis and it should be part of the responsibilities of a security administrator. Talking about Windows operating systems, there is this feature called Windows Automatic Update that you must turn on to let it automatically receive and install critical or non-critical updates from the Microsoft update website. This feature has been there since Windows 98 and has had a lot of improvements over the years.

Apart from this feature, Microsoft has a really great tool which needs to be downloaded and installed from here and it is called Microsoft Baseline Security Analyzer. This tool is a type of vulnerability scanner which can scan Windows servers and computers and find security miss-configurations and problems and report them to you. Then you will take necessary actions to eliminate those security vulnerabilities.

Using MBSA 2.2 which is the latest version of this tool, you can look for the missing updates in the versions of windows being scanned and this tool will also detect security miss-configurations on some of Microsoft software and services installed on Windows. You can see a list of those software that are checked during the scan on the page I mentioned above.

There are so many other security vulnerability scanners too but this one is only designed for Microsoft Windows operating systems. Below is a few more security scanner tools that you can use:

Retina Network Security Scanner

GFI Languard Network Security Scanner

Nessus Security Scanner

Microsoft Domain and Server Isolation at a Glance

Some months ago back in 2010 I had a talk on Microsoft Domain and Server Isolation in Techinsights 2010 conference in Kuala Lumpur and I just thought why I shouldn’t share the slides with you?!!

So here you go: (You’d better download the slides to have a better view)
