You could use Bootvis (http://www.microsoft.com/hwdev/fastboot/) for
this, but I prefer to clean up the startup settings for this.
Applications that start with Windows can be found here:
- the WIN.INI, section [windows], entries "run=" and "load="
- the Registry keys
HKEY_CURRENT_USER\Software\Microsoft\Windows\CurrentVersion\Run
HKEY_LOCAL_MACHINE\Software\Microsoft\Windows\CurrentVersion\Run
HKEY_LOCAL_MACHINE\Software\Microsoft\Windows\CurrentVersion\RunServices
- the folders
C:\DOCUMENTS AND SETTINGS\ALL USERS\START MENU\PROGRAMS\STARTUP
C:\DOCUMENTS AND SETTINGS\{username}\START MENU\PROGRAMS\STARTUP
Remove all things that you do not need.
