Just now when we posted about new WhatsApp update for Windows Phone, Here comes the surprise launch of WhatsApp for Windows 8 and Windows 10 PC.
WhatsApp launched the executable file for PC version. That means you it is not available through store. The interface of this is very similar to WhatsApp web. Users will have to scan QR code to execute the program and WhatsApp must be installed on the Mobile.
After installing the program, you can set it up to receive notifications in the notification bar just like you do in Mobile version if you are on Redstone Build.
