Step 4. Delete Index.dat file to Tune up your PC.
Step 5. Run Disk Cleanup (Cleanmgr)
Step 6. Delete Old Shadow Copies from your computer
Steps 7. Adjust visual effects for best performance and increase virtual memory
Steps 8. Check your Hard drive for Errors (Run CHKDSK)
Steps 9. Run Disk Defragmentation.(Defrag)
Step 10. Remove unnecessary items from start up
Step 11. Use a PC optimization Software or a Tuneup Utilities.
Step 12. Do a little tweak in registry to Tune up your computer
Now the next step is to make a little changes in registry to make your computer super fast.So go to Run dialog box and type regedit to open registry editor and then make changes to the following registry key with the below mentioned key value to tune up your slow PC.
And I would recommend you to take the backup of the registry before you make any changes so that if you do any thing wrong or delete any of the keys by mistake you can always restore the registry back.
To back up the registry key right-click on the Registry key you plan on changing, and click "Export." The Registry Editor will prompt you to save a .reg file to your hard drive.
To undo Registry changes, just find your .reg file and double-click it. The .reg file will reset your Registry values to their existing values (but will not remove values that you've added).
[HKEY_CURRENT_USER\Control Panel\Desktop]
"AutoEndTasks"="1"
"HungAppTimeout"="1000"
"MenuShowDelay"="8"
"WaitToKillAppTimeout"="2000"
"LowLevelHooksTimeout"="1000"
[HKEY_CURRENT_USER\Control Panel\Mouse]
"MouseHoverTime"="8"
[HKEY_CURRENT_USER\Software\Microsoft\Windows\CurrentVersion\Policies\Explorer]

[HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control]
"WaitToKillServiceTimeout"="2000"
[HKEY_CURRENT_USER > Software > Microsoft > Windows > CurrentVersion > Explorer > Advanced]
"DesktopLivePreviewHoverTime"="set the value according to your need, see below for the description"
"ExtendedUIHoverTime"="200"
"ThumbnailLivePreviewHoverTime"="600"
[HKEY_LOCAL_MACHINE\SYSTEM\ CurrentControlSet\Control\Session Manager\Memory Management]
"DisablePagingExecutive"="1"
AutoEndTasks - Forces Windows to automatically end user services when the user logs off or shuts down the computer.
HungAppTimeout - Reduces system waiting time before killing user processes when the user clicks on "End Task" button in Task Manager.
MenuShowDelay - Decreases menus show delay time, it'll make the menus show faster upon clicking.
WaitToKillAppTimeout - Reduces system waiting time before killing user processes when the user logs off or shuts down the computer.
LowLevelHooksTimeout - Reduces system waiting time before killing not responding services.
MouseHoverTime - Reduces popup delay time to show popup description faster when you move mouse cursor over an item.
ThumbnailLivePreviewHoverTime - Whenever you move the mouse cursor to the taskbar over a running application icon, the thumbnail preview of the running application becomes visible. Also when you move cursor to the Live Preview Thumbnail (then all the running applications will become transparent and the application for which you have moved the cursor on will become active, to give you a clear display of the application. You will experience that windows is taking sometime to display the running application when you move the mouse cursor on its Live Preview Thumbnails.In order to Tune up your PC adjust this live preview delay time to the desired value for this key.
DisablePagingExecutive - Setting the value 1 for this key will move the windows Kernel (ntoskrnl.exe) to system memory.If the Windows Kernel is in system memory(RAM), it will run slightly faster than if it were on your hard drive.Setting this value to 1 is useful when debugging drivers, because all of the code and data is always memory resident. It also improves performance on machines with a lot of memory, because it prevents disk reads to get code or data and is the best tune up step.
To make the most of it I personally recommend you to use this tweak only when you have more than enough RAM for your workload otherwise on low memory systems this can force application code to be needlessly paged and reduce performance.
