“This isn’t an unusual repair process for a Windows
system. Even for Vista there are plenty of examples of command
window (cmd.exe) and regedit repair instructions in Microsoft’s
support pages. You can ignore all the myths floating around the
Internet about never having to use Unixy command lines when
administering Windows systems because of the wonderful graphical
tools. On Windows there are many tasks that are impossible to
perform with graphical tools or are just a lot easier from a
command window. The only way to avoid command line tools or regedit
entirely is to write a custom graphical tool that handles those
specific situations (similar to “compiling a kernel” comments from
Microsoft fanboys).”
