WindowsUpdate Foutcode code 80070057 trying to do a Window update

[des]

Ik heb Windows Vista Businesscode op mijn Laptop en kreeg d vollgende Foutmelding tijdens Windows Update  80070057
Ik kreeg van Microsoft Support het advies om o.a. de onderstaande handelingen te doen, maar ik kan "Appwiz.clp"niet vinden op mijn Laptop!!!

Wie weet de Nederlandse benaming hirvan? Wie kan mij verder helpen SP2 van mijn Laptop te verwijderen?

Method 1: Uninstall the prerelease version of SP2 via Programs and Features
=========================================================
1.   Click Start, type Appwiz.cpl in the Start Search box, and then click Appwiz.cpl in the Programs list.
 
If you are prompted for an administrator password or for a confirmation, type the password, or click Continue.
 
2.   Click View installed updates.
3.   Click the service pack (KB948465), and then click Uninstall.

Bij Mthode 2 kan ik niet "right klick op de commandepromt uitvoeren! Hoe kan dat? Ik krijg ook geen vermelding om door te gaan als Administrator?

 
Method 2: Uninstall the prereleased version of SP2 via Command Prompt
======================================================
Note: If you have used the Disk Cleanup Wizard, it may have removed some temporary installation files which are needed to uninstall the Windows Vista service pack. If this is the case, this method may not work for you.
 
1.   Click Start, type Command in the Start Search box, right-click CommandPrompt, and then click Run as administrator.
2.   Run the following command, as appropriate for the version of the Windows Vista service that you want to uninstall:
 
C:\temp\Windows6.0-KB948465-x86.exe /x:C:\temp
 
3.   We have to create a sandbox environment before you can continue to step 4. This helps us safely run an untrusted program. To create a sandbox, type the following command:
 
md sandbox
 
4.   To remove the Windows Vista service pack, type, or copy and paste the following command, as appropriate for the version of the Windows Vista service that we want to uninstall:
 
start /w pkgmgr.exe /m:c:\temp\Windows6.0-KB948465-x86.cab /up /s:sandbox
 
5.   After Pkgmgr.exe finishes, you will be prompted to restart the computer to complete the uninstall process.

"maar ik kan "Appwiz.clp"niet vinden op mijn Laptop". Dat klopt, want het onderdeel heet Appwiz.cpl en staat in de map c:\Windows\System32 (ook in de NL versie).
Het is trouwens hetzelfde als ConfigScherm (klaasieke weergave)-> Programma's en onderdelen.
