How to download Windows 10/11 iso using a M1 MacBook Pro

I’ve recently tried UTM on my Apple Silicon MBP to test Windows 11. To install Windows 11, I needed a recent iso image. This blog post explains how to download the iso files for Windows 10 or 11.

Go to UUP dump. This page lists all available UUP files from Windows Update servers.

Search for „feature update Windows 10“ or „Windows 11 Insider Preview“ and select a recent version for the required architecture (e.g. x64). Click on next.

Select a language and click next.

Select an edition, like „Windows Pro“ and click next.

Select Download method „Download and convert to ISO“. Check „Include updates“ and click on „Create download package“.

Extract the resulting file. You’ll see three scripts:

  • Windows: uup_download_windows.cmd
  • Linux:
  • macOS:

Make the executable by using „chmod +x“ and try to execute it.

It will probably complain about missing files. But at the same time, it offers help on what you’ll need to install using homebrew, e.g.:

brew tap sidneys/homebrew
brew install aria2 cabextract wimlib cdrtools sidneys/homebrew/chntpw

On my M1/Apple Silicon Mac, chntpw complained about a non working SSL. I’ve found this issue on Github, which has some easy installation recommendations:

curl -LO
curl -LO
brew install --formula --build-from-source ./openssl@1.0.rb
brew install --formula --build-from-source ./chntpw.rb
rm ./openssl@1.0.rb ./chntpw.rb

Now try to execute the script again. It will now download the requested update files and will create automatically a nice ISO file, which can be used to install Windows.

As we’re using the official Windows Server Update files, this method should be legal. There is a more detailed report available ag which explains, that most of the tool was developed by analyzing the network traffic of a Windows installation running updates. It’s also a good way to get the versions including the latest updates including the Insider builds. Of course there’s still the official download page from Microsoft.

How to enable Xbox 360 Audio over HDMI connection

I was trying to connect my Xbox 360 to my shiny new Sony Bravia KDL-46EX720BAEP Flatscreen. I thought it would be sufficient to plugin a HDMI cable and I would be all set. The screen was immediately detected, but I heard no sound from the console. It took me a few minutes to find this awesome hint which allowed me to hear sounds from the Xbox 360 again:

You have to disable the automatic screen detection inside the Xbox 360 console settings. The console will restart and after this restart I was able to hear again.

Microsoft Windows Phone 7 und der erste Virenscanner

Small update: please use Google Translate for an english version. I still need time to think about a good multilanguage solution for this blog 🙂

Es war nur eine Frage der Zeit, bis der erste Virenscanner für Microsoft Windows Phone 7 erscheint. Gestern war es dann „endlich“ soweit: AVG Mobilation Anti-Virus Free

Nun ist es aber so, dass die App ganz normal vom Microsoft Marketplace geladen werden kann. Was bedeutet das für die App?
