There are some "backlisted" Serials from Microsoft. If you have such ja serial. (e.g. : xxxxx-640-xxxxxxx-xxxxx) you can´t install Windows XP Service Pack 1
Here is how it works :
1. Regedit -> HKey_Local_Machine\Software\Microsoft\WindowsNT\Current Version\SPAEvents -> right click on "obbetimers" and change the last digit!
2. Run from StartMenu -> %systemroot%\system32\oobe\msoobe.exe /a
(2a. If nothing happens if you do Step 7, you have to download XPAntiSpy and choose default value for regwizc.dll and licdll.dll)
3. Choose "Activate by phone"
4. Choose "Change Produkt Key"
5. Enter "7FMM3-W4FMP-4WRXX-BKDRT-7HG48"
6. Close window and reboot
7. Run from StartMenu -> %systemroot%\system32\oobe\msoobe.exe /a
(7a. If nothing happens if you do Step 7, you have to download XPAntiSpy and choose default value for regwizc.dll and licdll.dll)
8. It should say : "Windows is already aktivated"
9. Installl "Windows XP - Service Pack 1" !
10. Choose after install -> Reboot now
11. Don´t Panik, if the first reboot doesn´t work! Simply "Hard-Reset" and boot normaly again !
12. Login and XP-Service Pack 1 installed without "new" Activation !
13. M$-Guys -> I´ve kicked you again !
