How to Install Windows 7 If It's Stuck at Expanding

Microsoft Windows 7 is installed to a computer's hard drive through different stages, one of which is the expanding stage where the Windows system data files are transferred from the installation device to the computer's internal hard drive. This stage of installation may not complete and remain stuck if certain things within the computer system go wrong. For example, if the computer is experiencing a hardware malfunction, it may cause Windows 7 to remain in the "expanding" stage and not complete.
