Now i have Vista as a dual boot Ive been cutting a few things out "just the normal MS junk"

Turn off Windows Hibernation

Windows hibernation background services can use a large amount of system resources. If you don’t use the Hibernate feature on a regular basis you may want to disable it to give Vista a performance boost.

To disable Hibernation - 1) Select the Control Panel then Power Options, 2) Click Change Plan Settings, 3) Click on Change Advanced Power Settings, 4) Expand the Sleep selection, 5) Expand the Hibernate After selection, 6) Crank the selector down to zero, 7) Click Apply.

Turn off Remote Differential Compression

Remote Differential Compression measures the changes in files over a network to transfer them with minimal bandwidth rather than transferring an entire file that has previously been moved. By constantly checking for file changes, this service can hinder system performance, to disable this service -

1) Open Control Panel, 2) Switch to Classic View, 3) Select Program Features, 4) Choose Turn Windows features on and off, 5) Scroll down and uncheck Remote Differential Compression.

Turn off Automatic Disk Defragmentation

Windows Vista and its always-on defragment feature isn’t really that necessary and can cause system slow down. Just remember to run a defrag manually every week or so.

To disable this 1) Click Start then Computer 2) Right Click the C: Drive 3) Click on Properties 4) Select the Tools Tab Click on Defragment 5) Now Uncheck Run on a schedule 6) Reboot.

Turn off Windows Search Indexing

Windows Vista search indexing is constantly reviewing files on your system to make their contents available for quick searching. This is handy, but can severely impact system performance.

To disable constant indexing >

1) Click Start then Computer. 2) Right Click the C: Drive / Boot Drive On General Tab. 3) Uncheck Index this drive for faster searching On the subsequent dialogue box. 4) Select Include sub folders and files. 5) Reboot.

Disable User Access Control (UAC)

This much-loathed new Vista feature attempts to protect your system from malware infection by making you manually confirm a whole host of everyday user operations. While it doesn’t directly impact performance, it can be annoying and might be more hassle than good, Microsoft seems to think most PC users are a bit dim

To disable User Access Control

1) Click Start then Control Panel 2) Select User Accounts 3) Select Turn User Account Control on or off 4) Uncheck User Account Control Box 5) Restart as recommended.

Add a 2GB or higher USB Flash drive to take advantage of Windows Ready Boost (Additional Memory Cache)

Ready Boost is Microsoft’s name for using a USB thumb/flash drive to provide some quick access memory the operating system can use as extra RAM. The Ready Boost system can significantly improve system performance.

To set this up

1) Insert a USB Flash Drive 2) Click Start then Computer 3) Right Click the USB Drive in My Computer 4) Select the Ready Boost Tab 5) Choose Use this device 6) Select as much space as you can free up for RAM usage vs. Storage. "I tried with a 8GB Flash Drive and it worked well (Vista Ultimate)"

Turn off Automatic Disk Defragmentation

Windows Vista and its always-on defragment feature isn’t really that necessary and can cause system slow down. Just remember to run a defrag manually every week or so.

To disable this

1) Click Start then Computer 2) Right Click the C: Drive / Boot Drive 3) Click on Properties 4) Select the Tools Tab 5) Click on Defragment Now 6) Uncheck Run on a schedule 7) Reboot.

Disable excess Windows Services that Auto-Launch at Startup

Just like Windows XP, Vista ships with all kinds of services enabled that load at startup and may never be used by most users.
To see what loads at startup and disable the ones you likely won’t be needing (they can always be started manually later)

1) Click Start then Control Panel 2) Select Administrative Tools 3) Choose System Configuration 4) Click the Services Tab > You may want to deselect

> Offline Files (unless you’re using Offline File Sync)
> Tablet PC Input Service (unless you have a tablet PC)
> Terminal Services
> Windows Search (If you have already disabled indexing)
> Fax (unless you’re using a fax modem)

My computer don't want to do it. After several minutes, I received a message "An error has occurred. Not all of the features successfully changed". Do you know why? It is important to improve the speed?
