There have been a lot of complaints going around in the web of slow start-ups and shut-downs of Windows Vista after they have ugraded their Windows XP box. There were also some complains on newly purchased hardware where Windows Vista took 5 to ten minutes to start and shutdown.
Microsoft denied reports that Windows Vista is slow and passed the finger on vendors configuration.
I have experienced Windows Vista running extremely slow after upgrading some Windows XP machines. I don’t think there is a fault on Windows Vista but it is common sense that performance would suffer given that I have upgraded the OS without upgrading the machine. I have not experienced any performance issues on newly purchased hardware machines given the Intel Core 2 Duo, 2GB or RAM on it.
Windows Vista definitely needs a high end machine and complaints on performance issues could very well be traced to machine specs.
