Hi all, I had windows 8.1 up-to-date until yesterday when my Dad deleted some of the system folder/files by mistake and now it's not booting up. Anyway, I was thinking of doing a fresh install. So my question is, is the .iso that we download from Windows 8.1 Upgrade Appliation is kept up-to-date? I don't want to download the all the updates again. Is it possible to get a up-to-date bootable Windows 8.1 64-bit disk with all the updates? I want to do it in one go.
