I found a thread on-line claiming that these files are provided by Microsoft to upgrade to Windows 10 in the form of ESD files. Before I proceed downloading I want to ask: Are those real? It's not the 29th yet!
And if so I don't have to download the update. Please let me know if this link (Direct download) actually can upgrade to Windows 10 without waiting!
P.S: I linked the 8.1 Pro because that's my OS!
