Accelerate / SpeedupWindows 7 Start Up

Choose programs to run at startup:
Many programs are loaded automatically when
Windows starts. The launch of some of them at
startup is perfectly justified as firewalls, antivirus,
download manager. Others, however, are not
necessarily needed as the QuickStart Microsoft
Office, the Officers Winamp, RealPlayer, Java, or
even software installed without your knowledge
… You can prevent their launch.
Click the Start button, type msconfig in the
search field … and confirm by pressing Enter.
In the window that appears, open the Startup tab.
The list of all running programs at startup is
displayed. Then uncheck the boxes to disable the
software. Click OK.
Click on Exit without restarting.
If an error occurs, you can easily find the
automatic execution of the software by checking
the box again.
Disable the boot-time defrag:
By default, Windows Vista and Windows 7
defragment system files every time you boot the
PC. However, if you defragment your disk
regularly, this automatic feature is unnecessary
and it slows the release of Windows. To disable
it, you must edit the Windows registry.
Click the Start button, type the command regedit
in the Search box and press the Enter key.
In the editor that opens, scroll down the
HKEY_LOCAL_MACHINE, SOFTWARE, Microsoft,
Dfrg, BootOptimizeFunction.
Double click on the value Optimizecomplete.
In the Value Data field, enter No to Yes’s place.
Click OK.
Finally close the window of the Registry Editor.
The change will be effective from the next
Windows startup.
