Hi Sandeep,
I'm actually using Windows 8 version 6.2. I saw under one of the section "•PCs running Windows RT or Windows 8 can't join a domain. You can only join a domain if your PC is running Windows 8 Pro or Windows 8 Enterprise.", which means that my laptop is unable to connect to my workplace's network if I'm using Windows 8? Is there a way I could resolve this issue?
