PowerShell – Using PowerShell 5 to automate the installation of your favorite Windows applications

In this blog post I will explain why to automate installations of Windows applications and how you can do this.

Why automate the installation of applications?

But first, why is this useful? Well this depends on your situation and there are probably many good reasons. For me though, it basically boils down to this:

  1. I often reinstall my computers with new (preview) versions of Windows operating systems and having to install applications each time is a waste of time. Also sometimes you forget to install some things.
  2. On a regular basis, friends and family either want me to install or upgrade their PC and I want to provide them with a standard set of programs that most people need/want without having to spend a lot of time on it. By example virus scanner, burning program, media player, codecs, etc.
  3. I want to update existing installed applications to the latest (and hopefully more secure and feature packed) versions.
  4. When installing applications, there are often checkboxes enabled to install other applications (you generally don’t want to install). Automated solutions using packages generally prevent these additional unwanted applications from installing.

Which tools to use to automate the installation of applications?

Before PowerShell 5 preview was released, I used both Ninite and Chocolatey to perform to automate installations. They both have their advantages as described on this wiki page.

The PowerShell 5 preview version of OneGet installs and searches software from Chocolatey repositories, but support of additional repositories will come in subsequent versions.

How to automate the installation of applications using PowerShell 5 preview?

To automate the installation of applications a couple of things are required:

  1. You need to determine which applications you want to install automatically.
  2. You need to determine the package name that Chocolatey uses for this application. Options include:
    -Using a browser to browse the Chocolatey packages
    -Using PowerShell and a part of the name of the application you’re looking for. By example if you’re looking for Irfanview, use:
    Find-Package -Name “fan”
  3. Store the package names to install somewhere (e.g. in a .txt file on OneDrive for easy access). My .txt file by example includes:
    AdobeReader
    Directx
    ffdshow
    Flashplayerplugin
    GoogleChrome
    Imgburn
    IrfanView
    Javaruntime
    Keepassx
    Mp3tag
    mpc-hc
    PDFCreator
    Silverlight
    TeamViewer
    Totalcommander
    Winrar
    greenshot
  4. Use the Install-Package cmdlet to install all the packages whose name is in the file from step 3.
    Install-Package -Name (Get-Content C:\OneDrive\AppsToInstall.txt) -Confirm:$False
  5. Wait for the programs to install

My opinion

It’s great to be able to use PowerShell to install my list of favorite applications similar to like I did with Chocolatey and I’m also looking forward to see what benefits the additional repositories will bring in the future.

I did encounter some errors however while trying to install some applications like Firefox and dotnet3.5. But since it’s still a preview, this will probably be fixed.

For regular users, I think they are better off sticking to by example Ninite because they’re often afraid of anything that involves a CLI.

Blog posts by other people about OneGet

Some other people have also blogged about the OneGet module and have gone in more technical detail, so be sure to take a look at their posts as well:

Windows Management Framework v5 preview, includes also Desired State Configuration (DSC) improvements and NetworkSwitch commandlets to manage network switches that pass the Certified for Windows Program. For more information including a download link, you can read the initial blog post. : Windows Management Framework V5 Preview

Microsoft – Passed the free exam 74-409 Server Virtualization with Windows Server Hyper-V and System Center

As I mentioned earlier, Microsoft is offering free exam vouchers for the new exam “74-409 Server Virtualization with Windows Server Hyper-V and System Center”. For more information, take a look here.

I took the exam today and passed after having studied very hard for over a week (including pulling an all nighter today). I’m happy to have my first certification for the year 2014 already though :)

In my opinion the exam contained too many repeating (easy) questions on specific subjects, but there were also some very difficult questions about really specific situations. I personally would’ve preferred more “medium difficulty” questions.

All in all I learned a lot from preparing for the exam and I’m very happy with all the new things Microsoft has added to their new products.

If you are looking to take the exam as well, take a look at my previous post that contains the resources I used for preparation.

Good luck and enjoy. I’ll be going for some well earned sleep now :)

Microsoft – Preparing for free exam 74-409 Server Virtualization with Windows Server Hyper-V and System Center

Exam dumps

Unfortunately I’ve received numerous requests for an exam dump of 74-409 which really upsets me.

For those that are not aware of it, you are not allowed to share or use exam dumps. “If Microsoft learns that a candidate used a “brain dump” site to prepare for an exam, this candidate will be permanently banned or prohibited from taking any future Microsoft Certification exams and may be decertified from the Microsoft Certification Program. In addition, test scores and certifications, if applicable, may be revoked. These actions may be taken even if the candidate did not intend to defraud the Microsoft Certification Program.”

For more information, see:
http://borntolearn.mslearn.net/btl/b/weblog/archive/2013/01/02/why-brain-dumps-are-bad.aspx

Preparing to take the exam

This is generally what I do for preparing to take the exam:

  1. Determine the skills that are measured in the exam 74-409
  2. View the online course Server Virtualization with Windows Hyper-V and System Center at Microsoft Virtual Academy (MVA)
  3. Reflect how confident you are that the online course has provided you with sufficient skills to take the exam.
  4. Optionally enhance your knowledge using:

Specific topics and resources I used while studying:

The Openbox / Skybox , a cheap HD sattelite receiver that provides a lot of bang for the buck

Introduction

A couple of years ago I bought a Dreambox DM-800HD sattelite receiver. At the time, HD receivers were pretty expensive (300-400 euros) and there weren’t many good alternatives. I wanted additional HD receivers, but I wasn’t willing to pay 300-400 euros a piece. As such, I started investigating and found out that you could get an Openbox / Skybox HD receiver for about 70 euros including shipping, so I was quite interested and bought an Openbox S11. I’ve been using it for a couple of years now with a duo LNB with Astra 1 (19,2) and Astra 3 (23,5) and I’m very satisfied with it.

Advantages

  • It’s cheap and provides a lot of bang for the buck.
  • It provides good image quality.
  • It supports cccam.
  • It boots very quickly.
  • The remote is easy to use and comfortable in your hand.
  • You can timeshift / record to an USB drive.
  • You can play multimedia from an USB drive. Music, Images, Video (including MKV X264 !!!! ).

Disadvantages

  • Menus and options are very basic.
  • Only a single tuner.
  • Lack of support.
  • Custom firmwares are limited.
    • Hard to find out which firmware is best. Each has its own advantages and disadvantes.
  • Creating channel lists / favorites from the device itself is very time consuming and troublesome.
    • You can use external tools to create channel lists. By example Ali Editor / PVR800-Editor or MediaBox Editor Studio (MES). Even with these tools, the editing experience is not as good as I was used to with my Dreambox.
    • Already created channel lists / favorites can easily be shared using either USB or over the network using STBHD_LAN_MM.

Conclusion and advice

If you’re looking for a sattelite HD receiver that provides more bang for your buck, be sure to take a look at the Openbox / Skybox HD receivers. While I paid 70 euros back then, they can now be had for about 50 euros including shipping. Keep in mind though that initial configuration can require some manual work. After that you can simply re-use your configuration.

There are now many more versions available of the Openbox / Skybox however and I have to admit that it’s often not clear to me which types provide which advantages so be sure to take a look at this as well. Versions include the S9,S10,S11,S12,S16,S18,F3,F4,F5,X3,X4,X5,X6,S1000,S6000HD. Also keep in mind that there are a lot of clones available. Personally I just ordered the X6 here because I want a spdif output, I’ll write a review about it as soon as I receive it.

For people looking for HD sattelite receivers that provide more features, take a look at the Vu+ Solo2 or Duo2 that have been reviewed very well, but are also a lot more expensive.

ICT – Great article by Paul Simoneau about ICT challenges including suggestions to deal with them

As an ICT professional I believe working in ICT can be very challenging. Paul Simoneau wrote a great article about current and future challenges including suggestions to deal with them.

The challenges covered in the article are: new technology, cloud, big data analytics, virtualization, Bring Your Own Device/Apps (BYOD/BYOA), shadow IT, new generations of workers, energy  efficiency, user systems, creating value, interoperability and social networks.

I wanted to share this article because I feel it reflects reality very well.

Apple – Create an OS X 10.9 Mavericks bootable USB flash drive or ISO

This week Apple released OS X 10.9 Mavericks for free through the App Store. Even though downloading from the App Store works great for updating, I also want to be able to perform a clean install and create VMs running OS X 10.9 Mavericks. I also don’t want to download the 5+GB update file every time I upgrade a system.

Unfortunately Apple doesn’t provide an ISO download or a tool to create an ISO or bootable USB drive. There are however many people with similar needs that provide information on how to create both. The downside of these methods though, is that you need to have a working OS X system to be able to use them.

VMware – Free VMware Certified Associate (VCA) exam vouchers for a limited time

Free certification information

For a limited time only, you will be able to get free VMware Certified Associate (VCA) exam vouchers and get certified by taking the exams from the comfort of your own home.

Update 06-12-2012 : Rasmus Haslund added a new method: http://www.perfectcloud.org/certification/vmware-vca-exam-experience-plus-free-exam-voucher/

Update 24-11-2013 : Rasmus Haslund provided a new code on his site : http://www.perfectcloud.org/certification/vmware-vca-exam-experience-plus-free-exam-voucher/
Give code VMRT9B503121 a try.

Update 22-11-2013 : Apparently the codes are not working anymore, see the comments. You could give code VMRT1B01791B a try.

Update 19-10-2013 : Apparently Global Knowledge provides a code as well. Can be used until January 31st: http://www.globalknowledge.com/training/generic.asp?pageid=3596

Update 09-11-2013 : Eric Sloof from ntpro.nl provides a code as well. Can be used until January 31st: http://www.ntpro.nl/blog/archives/2471-Free-VMware-Certified-Associate-Certification-Extended.html

The currently available tracks which you can do for free are:

VMware Certified Associate – Datacenter Virtualization (VCA-DCV) – Exam blueprint
VMware Certified Associate – Cloud (VCA-Cloud) - Exam blueprint
VMware Certified Associate – Workforce Mobility (VCA-WM) - Exam blueprint

Free online e-learning modules are available that take about 4-5 hours to complete and that are sufficient to pass the exam. The registration process is a bit cumbersome in my opinion, but this blog post contains some instructions to help you with that.

From what I can see, this offer is valid until the end of October, but I might be wrong so it’s best to take the exams as soon as possible. I also think you’ll also be able to use the same voucher code to re-take the exam should you fail, but again I’m not really sure. Once I have more information, I will update this blog post.

Future additions

In the future a new track VMware Certified Associate – Network Virtualization (VCA-NV) will become available. It is not clear when it will arrive and if you’ll be able to use the voucher on this exam as well, but using the link you can at least have VMware notify you when it becomes available.

Usefulness

I think these free e-learnings are a good way to become familiar on a high level with VMware products, terminology and use cases. The VCA certification is proof you have this knowledge and might give you an advantage.

Being able to certify for free now can come in handy for:

  • People that are still studying.
  • People that are in between jobs.
  • People that are working in other parts of the ICT that are interested in VMware, but cannot get their employer to pay for VMware training/certification.
  • People and companies that want to stimulate certification, but also have to save costs.
  • People that are interested in virtualization and are considering doing more with it, but don’t know yet if it’s something for them.

There are of course more possible situations, but I think these are very common.

Thanks

Thanks to VMware for making this possible and Rasmus Haslund (@Haslund) for sharing the information and the voucher on his website http://www.perfectcloud.org, If you decide to use this offer, please also leave a comment at his website.

Also, as always … sharing is caring, so share this with others.
