Question

I was actually developing an add-on with the Add-on Builder but now I would like to change to SDK since there are more possibilities.
I have installed the sdk and Python like so:
C:\Users\bla\Add-ons\addon-sdk-1.8.1
(inside addon-sdk-1.8.1 I added the tar Python-2.6.8)
Now in the cmd I typed:

cd C:\Users\bla\Add-ons\addon-sdk-1.8.1  
mkdir my-addon  
cd my-addon  
cfx init  

That worked fine -> the folder my-addon has been created with the whole directory in it.
Then I deleted the folder my-addon and tried the same commands again and got:

'cfx' is not recognized as internal or external command, 
operable program or batch file.   

mddir my-addon created the folder my-addon. But cfx init produced the error.

It’s the first time I’m working with cmd commands and I have no clue what I gotta do now

You need to activate the sdk’s environment first, please see the installation docs:

https://addons.mozilla.org/en-US/developers/docs/sdk/latest/dev-guide/tutorials/installation.html

Essentially, you need to run the command

bin/activate

…from the root directory of the SDK. There are additional docs on the above link if you want to make the environment always available in your shell.
