Now that Vista has been released many people have implemented it’s use. Many users have found out that their PC does not run as crisp with this operating system. If you have implemented Vista on your PC with only the minimum system requirements you have seen how sluggish it can be. I thought I would put together a list of perfomance enhancing tweaks for users in this particular situation.
 

Disable User Access Control (UAC)

This feature protects your PC from malware infection by prompting you with a manual confirmation prompt anytime a program or even you attempt to alter or use features which can alter system critical information. This feature can be very annoying.

To disable User Access Control:

-Click Start then Control Panel
-Select User Accounts
-Select Turn User Account Control on or off
-Un-check User Account Control Box
-Restart as recommended

 Turn off Windows Search Indexing

Vista search indexing constantly reviews files on your PC to make their contents available for quick searching. This is a nice feature, but it can impact system performance.

To disable this constant indexing:

-Click Start then Computer
-Right Click the C: Drive
-On General Tab, Un-check Index this drive for faster searching
-On the subsequent dialog box, Select Include sub-folders and files

 Turn off ScheduledDisk Defragmentation

Vista and comes configured with hard drive defragmentation automatically scheduled. You must remember to run defrag manually.

To disable scheduled defragmentation:

-Click Start then all programs
-Select accessories and then system tools
-Select defragmentation
-Uncheck “Run on a schedule”

 Turn off Windows Hibernation

Windows hibernation background services use a large amount of system resources and hard drive space. This feature as well in previous versions has caused many blue screens and protection errors.

To disable Hibernation:

-Select the Control Panel then Power Options
-Click Change Plan Settings
-Click on Change Advanced Power Settings
-Expand the Sleep selection
-Expand the Hibernate After selection
-Move the selector down to zero
-Click Apply

Disabling System Restore: 

-Control Panel>System
-Click System Protection on the left panel

-Agree to the confirmation

-Choose Turn Windows features on and off
-Scroll down and un-check Remote Differential Compression

 Disable Windows Services that Auto-Launch

Vista is configured with many services enabled that load at startup and may never be used.
(these can be re-started manually by reversing the process; please document any changes you make)

Implementing Ready Boost

 Add a 2GB or higher USB Flash drive to implement Windows Ready Boost (Additional Memory Cache). There are many requirements for the devices which want to use this feature. Microsoft is working with manufacturers to label devices which are compatible with this feature. When purchasing such devices you will need to look for the Windows Ready Boost label.

To configure a USB device:

-Insert a USB Flash Drive (preferably 2GB or more)
-Click Start then Computer
-Right Click the USB Drive in My Computer
