You can grab the latest Windows Alpha Builds from here.
Just select whether build(i686/MINGW32=32bit build or x86_64/MINGW64=64bit build) you are using and navigate to the Artifacts tab to download the exe file.
The builds are updated whenever there is a new commit made on our GitHub repository.
Also as a side note, please just create a new topic instead of replying on an about thread. Those are only for explaining what the category is for.
