how to set up alexa app on windows 7

You moderators don't understand the question.  Your answer is for how to set up Alexa on a smart phone or tablet (apple or android).  The question is how to set it up on a Windows 7 PC.  The true answer is you can't.  It's funny that Microsoft has Alexa apps for IOS and Android but not for Windows, it's own product.

Alexa isn't Microsoft's product, it's Amazon's, and they are sadly not going to make/support an Alexa version for a soon-to-be-discontinued OS for they same reason they won't make an XP or Win98 or Win95 version, it's a waste of manpower (=money) for relatively little return when most PC users quit using 7 (if for no other reason lack of W7 drivers for new hardware when their old PC eventually dies from planned obsolescence or complete hardware failure). My solution is just forget about Alexa, it's an unnecessary gimmick unless you are too lazy to push a few buttons to get something done as has been done for the past several decades and downgrading to Win10 just for Alexa is a dumb idea in my opinion. And even if Alexa was Microsoft's product why would they make a W7 version? They want you to buy 10 and this is just another way to prod you into doing so.

You moderators act like typical IT geeks. Explain how to set it up in win 7 whether it be browser or otherwise. In Clear Laymans Terms!

I am not a moderator and a child would be able to tell that. It can't be done so don't get pissy at people telling you it can't be done.

Also, it's "Layman's" not Laymans.

I think what people are looking for here is a way to install an app or program on their PCs that allow you to control your Echo Dot (home automation, routines, music and so on) like you can with the Alexa app on your mobile phone.  If that's it, I think the only way is to install an Android emulator like Bluestacks ( www.bluestacks.com )on thier PC.  They can then download the Alexa app directly from Google Playstore and run it like they would on their phones.
