 ## Compressing the .vhdx file
 
 The .vhdx file produced by the second step should be renamed to **kutti-\<kubernetes version\>.vhdx**, and then compressed to a file called **kutti-\<kubernetes version\>.vhdx.zip**. **NOTE:** Do not use Windows Explorer to create the .zip file. On Windows, use 7Zip instead.
