Why my window vista operating system takes too much time in starting?

Windows vista operating system is the product of Microsoft Corporation. Windows vista is the 3rd generation operating system from Microsoft, it’s not a successful operating system, as you said that you are facing problem with its startup, you said that its take too much time to start, so I want to tell you that basically this problem occurs due to any heavy software install on your computer system or due to any un trusted software which may be installed on your computer system. The other reason for this problem is due to a large amount of temporary files and cache memory, so I request you to please clean the disk clean up of your computer system and also delete the temporary file of your computer system. After doing this your computer system runs faster. I suggest you to move on the advance version of Microsoft operating system. Microsoft launches its new operating system that is windows 7 it’s the advance version of windows vista so I suggest you to use the windows 7 operating system instead of windows vista. Windows 7 is a very smart and very fast operating system.
