I have added some new tweaks to my Tweaks.reg file in my unattended XP CD, they seem to be causing me some issues, my computer now takes almost 3 years to shutdown or restart. The entries in the code box below are the new entries, I have tried the installation without these and shutting down or restarting is fine. ; Remove Print From TXT Files [-HKEY_CLASSES_ROOT\txtfile\shell\print] ;-------------------------------------------------------------------------------------------------------------------------------- ; Remove Print From Images [-HKEY_CLASSES_ROOT\SystemFileAssociations\image\shell\print] [-HKEY_CLASSES_ROOT\SystemFileAssociations\text\shell\print] ;-------------------------------------------------------------------------------------------------------------------------------- ; Remove Print From REG Files [-HKEY_CLASSES_ROOT\regfile\shell\print] ;-------------------------------------------------------------------------------------------------------------------------------- ; Remove Print From CMD Files [-HKEY_CLASSES_ROOT\cmdfile\shell\print] ;-------------------------------------------------------------------------------------------------------------------------------- ; Remove Print From Batch Files [-HKEY_CLASSES_ROOT\batfile\shell\print] ;-------------------------------------------------------------------------------------------------------------------------------- ; Remove Print From INI Files [-HKEY_CLASSES_ROOT\inifile\shell\print] ;-------------------------------------------------------------------------------------------------------------------------------- ; Remove Print From INF Files [-HKEY_CLASSES_ROOT\inffile\shell\print] ;-------------------------------------------------------------------------------------------------------------------------------- ; Remove Print From PHP Files (Change AppName, To Name Of Default App For File Type) [-HKEY_CLASSES_ROOT\AppName.php\shell\print] ;-------------------------------------------------------------------------------------------------------------------------------- ; Remove Print From PDF Files (Change AppName, To Name Of Default App For File Type) [-HKEY_CLASSES_ROOT\AppName.Document\shell\print] ;-------------------------------------------------------------------------------------------------------------------------------- ; Remove Print From Word Docs [-HKEY_CLASSES_ROOT\Word.Document.8\shell\Print] ;-------------------------------------------------------------------------------------------------------------------------------- ; Remove Print From PowerPoint Docs [-HKEY_CLASSES_ROOT\PowerPoint.Show.8\shell\Print ;-------------------------------------------------------------------------------------------------------------------------------- ; Remove Record From Wave Files [-HKEY_LOCAL_MACHINE\SOFTWARE\Classes\SoundRec\shell\record] ;-------------------------------------------------------------------------------------------------------------------------------- ; Remove "Print" option from the context menu for image & text files [-HKEY_CLASSES_ROOT\SystemFileAssociations\image\shell\print] [-HKEY_CLASSES_ROOT\SystemFileAssociations\text\shell\print] ;-------------------------------------------------------------------------------------------------------------------------------- ; Remove the Map and Disconnect Network Drive Options [HKEY_LOCAL_MACHINE\Software\Microsoft\Windows\CurrentVersion\Policies\Explorer] "NoNetConnectDisconnect"=dword:00000001 ;-------------------------------------------------------------------------------------------------------------------------------- ; Faster reboot time [HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows NT\CurrentVersion\Winlogon] "EnableQuickReboot"="1" ;-------------------------------------------------------------------------------------------------------------------------------- ; Disables Backup System Files with Successful Boot [HKEY_LOCAL_MACHINE\Software\Microsoft\Windows NT\CurrentVersion\Winlogon] "ReportBootOk"="0" ;-------------------------------------------------------------------------------------------------------------------------------- ;Prevents Windows Messenger from being updated [HKEY_LOCAL_MACHINE\SOFTWARE\Policies\Microsoft\Messenger\Client] "PreventAutoUpdate"=dword:00000001 "PreventBackgroundDownload"=dword:00000001 ; Disable Default Hidden Shares - This keeps Windows from creating the Admin$, C$, etc. shares (which are security holes) automatically on start-up.

Tweaks.reg EDIT: I have been messing around and I changed the entry below from 5000 to 1000, this matches it up with the "WaitToKillAppTimeout" tweak, it seems now my computer shutdown instantly.. well it should no doubt. I am now adding the all the new tweaks back in + this "WaitToKillServiceTimeout" tweak to see if it makes any changes. [HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control] "WaitToKillServiceTimeout"="1000"
