Make PC Run Faster Than ever by Using Registry Key :
Registry Tweak #1: Speed Up Aero Peek
Windows 7 uses Aero Peek to view the Desktop when you move your mouse curser over the Show Desktop button at the end of the Taskbar. This intuitive feature can cause an unwanted delay. You may speed up this function by performing the following steps.
Open the Registry editor by going to Start menu > Run > type in regedit.
Find the registry path HKEY_CURRENT_USER > Software > Microsoft > Windows > CurrentVersion > Explorer > Advanced.
Right-click on the right pan and select New > DWORD (32-bit) Value. Name the new DWORD DesktopLivePreviewHoverTime.
Double-click on DesktopLivePreviewHoverTime. Under Base, click Decimal and then enter a new delay time in milliseconds in the Value data field. Click OK. If you selected a very short delay, Aero Peek will function faster.
Log off and then log back on for the changes to take effect.
Registry Tweak #2: Speed Up Taskbar Previews
When you roll your mouse over open Taskbar items in Windows Vista and Windows 7, a preview will appear. The delay time for the preview to appear can be adjusted to speed things up. Follow the steps below to speed up Taskbar previews.
Open the Registry editor by going to Start menu > Run > type in regedit.
Find the registry path HKEY_CURRENT_USER > Software > Microsoft > Windows > CurrentVersion > Explorer > Advanced.
Right-click on the right pane and select New > DWORD (32-bit) Value. Name the new DWORD ExtendedUIHoverTime.
Double-click on ExtendedUIHoverTime. Under Base, click Decimal and enter a new delay time in the Value data field in milliseconds. Click OK to set the time (default is 400 milliseconds).
Log off and then log back on for the changes to take effect.
Registry Tweak #3: Speed Up Menus
To speed up the delay and navigation of menus in Windows Vista or Windows 7, you may follow the steps below.
Open the Registry editor by going to Start menu > Run > type in regedit.
Find the registry path HKEY_CURRENT_USER > Control Panel > Desktop.
Find MenuShowDelay and double-click it. Adjust the value in milliseconds to speed it up (default is 400 milliseconds, or just under half a second).
Log off and then log back on for the changed to take effect.
Registry Tweak #4: Speed Up Shut Down Time
When shutting down a Windows computer it may take several seconds to several minutes. To speed up this process, follow the steps below.
Open the Registry editor by going to Start menu > Run > type in regedit.
Find the registry path HKEY_LOCAL_MACHINE > SYSTEM > CurrentControlSet > Control.
Find WaitToKillServiceTimeout=3000' and double-click it. Adjust the value in milliseconds to speed it up. We recommend no less than 3000 milliseconds which is the time that Windows will allow other applications to close before shutting down the computer.
Log off and then log back on for the changes to take effect.
Registry Tweak #5: Disable Indexing to Boost Overall System Performance
Windows XP and Vista are known for offering a Search program that will continually run an indexing service to keep track of where most files are located. This function is not necessary and can take up a lot of processing power. To disable the Indexing program and speed up your hard drive, follow the steps below.
Open the Registry editor by going to Start menu > Run > type in regedit.
Find the registry path HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\WSearch and HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\cisvc.
For both entries, change the Start DWORD value to 4 (Start=dword:00000004).
Log off and then log back on for the changes to take effect.
Registry Tweak #6: Speed Up Windows Boot Time
Windows XP is notorious for taking a long time to boot or startup; therefore, we recommend you use a startup manager from a registry cleaner to speed up boot time without having to manually edit your Windows Registry. By making an edit in the registry, you can speed up your boot time and reduce the amount of time you waste waiting for your PC to simply startup.
Open the Registry editor by going to Start menu > Run > type in regedit.
Find the registry path HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\ContentIndex
In the right pane find the value called StartupDelay. Double-click it to open and then change the Base from Hexadecimal to Decimal and enter the value 40,000 (default setting is 480,000).
Restart your computer for the changes to take effect. Your computer should boot up faster.
Enjoy all of you guys..
