In all likelihood, the problem would get resolved over the phone and you can go ahead with your installation of Windows 8.1 or Windows 10. Follow these steps to extract the SSU: 1. If you are not happy with the First option posted above, you can always directly call Microsoft office by dialing the number “18009365700” and explain what error message you get in your Windows 8.1 operating system. To do this with the combined SSU and LCU packages now used for Windows 10, version 20H2 and Windows 10, version 2004, you must extract the SSU from the combined package. Note: The option “1” you chose means that you only used it once.Īfter following the steps above, you should get a confirmation ID and then you are ready to go with a workable product key. If you choose any other option it will not work.

Note: Type the installation ID in your phone. I waited a couple of days, and still Windows 10 hadn't activated. Relieved (and a little pissed off), I reinstalled Windows 10 via USB again.

Then press the “Enter” button on the keyboard.Type the command: “SLUI 4” in the “Run” window.
