Microsoft has managed to cut down on the installation time with every shiny new Windows OS release, but with Windows 7's numerous mouse clicks, four wizards and 60 windows involved in the setup process, there's still room for improvement. Even Redmond admitted as much in a recent study on upgrading PCs, realizing that way too many mouse clicks and wizards were involved in Windows installations. So to further streamline the install process for its upcoming OS, Microsoft promises Windows 8 upgraders with just one installation wizard that completes the entire OS setup in a span of 11 mouse clicks. The method covers a hardware compatibility scan, a check for which Windows 8 version works best for your PC, which then starts the install process, with the user being prompted throughout the setup. The Windows 8 web delivery feature also aims to do away with the 25-digit product key by including the key into the setup image itself. The Windows 8 development team has provided an in-depth preview of its streamlined setup process, so head on over to the Building Windows 8 blog for more details.
