You can already use WhatsApp on Desktop if you want to do so by using WhatsApp web option and it works fine except in the cases, when there is some issue with Phone connection. But now it seems WhatsApp wants to tap Windows desktop users by bringing a Windows 10 native client.
A Twitter account known for posting WhatsApp related leaks has posted two screenshots that may reveal plan to bring WhatsApp to Windows natively.
If you have a look at both the screenshots it does look like that WhatsApp is currently testing client for Windows. It is however too early and tool elementary leak to say anything with surety.
Thanks Oja for the tip. Cheers!!
