Windows Vista can be made faster by using the normal methods of computer optimization, but by doing a few other small tweaks you should get Vista running a whole lot faster than you would ever imagined.
I have separated them up into 4 groups;
Aero Desktop
Windows Aero is the graphical user interface and the default theme in most editions of Windows Vista, it makes the desktop look more advanced than XP but the problems with it is that it can reduce the speed of your computer. If you are running the Aero Desktop and have a computer with less than 2GB ram or if your video card is not up to scratch (Aero will not work if this is the case) than I suggest you should remove the desktop and use an alternative.
To de-activate Windows Aero just;
User Access Control
The User Access Control is a decent feature in Vista but I find it so annoying that every time I try to do something it pop-ups with question relating to whether I want to allow or deny what I am doing. I wouldn't have attempted to do it in the first place if I will deny myself!
To turn off the User Access Control you must;
More Memory
This is the simple section, more memory means a faster Vista. If your computer has anything less than 2GB of RAM than quickly go out and buy more, you will not regret it.
ReadyBoost
Windows Vista introduces Windows ReadyBoost, a new concept in adding memory to a system. You can use non-volatile flash memory, such as that on a universal serial bus (USB) flash drive, to improve performance without having to add additional memory "under the hood."
The flash memory device serves as an additional memory cache—that is, memory that the computer can access much more quickly than it can access data on the hard drive.
When a removable memory device such as a USB flash drive or a secure digital (SD) memory card is first inserted into a port, Windows Vista checks to see if its performance is fast enough to work with Windows ReadyBoost. If so, you are asked if you want to use this device to speed up system performance. You can choose to allocate part of a USB drive's memory to speed up performance and use the remainder to store files.
If you implement all these changes to your Vista operated computer you will noticed fast and immediate results in the speed and optimization of your computer.
