    Went through the steps to activate XP without product key. When I reboot the time dialog box with days left. I hit yes to activate and tells me that I am activated already. Hit ok and goes to windows. What happens when the days run out?

    • Rafaqat says:

      hope so it will be ok

      • John Massey says:

        What happens to the dialogue box when it reaches 0 days? What can be done to correct? What causes it to show when XP Pro has been activated?

      • John M. says:

        What happens when the days on the dialogue box zero out? Is the a solution I can use to solve this?

        • Rafaqat says:

          Yes you can use the above method to activate your windows

          • John M says:

            I went through the steps to activate without the product key. The dialogue box keeps showing on startup with days remaining. When I tell it to activate it tells me it is already activated and starts up. What happens when the dialogue zeros out? Will I still be able to start up? Is there a solution to correct this without going back to the steps or will I have to continue activating prior to start up with the dialogue box showing zero or will my program lock and won’t be able to get into the program?

          • Rafaqat says:

            just wait for the dialog box, if the problem still persist then go for the steps and try again to activate the windows.

          • John M says:

            When I put the command %systemroot%\system32\oobe\msoobe.exe \a it tells me that it has been activated. On start up and restart the timed dialogue box comes up even though it has been activated. Conflict? At wits end and the days are running out. Help! Went through the steps again. Same result.

          • Rafaqat says:

            It will be ok, if days are running out then just ignore it, at the end there will be a logo appeared if fake windows..just ignore it and follow the steps given in the article

          • John M. says:

            The dialogue box zeroed out. When I started it told me I needed to activate. Pushed yes and the already activated page came up. Hit okay and it brought me to the windows log in paqe. When I went to log in it told me that I need to activate. It became a circular event. Could not get into the program. What now?

          • Rafaqat says:

            The process is quite simple, if you have followed each step then it should be ok

  2. matthew says:

    when I reboot and type %system is says its not found does that matter? It says I’m activated, but after 30 days it says I need to activate my copy when I click activate it says its already activated then logs me out when I go to log in it says that I need to activate windows xp. it goes into that loop and i’m locked out of my computer. Ideas?

  3. Leon says:

    Best method I’ve seen so far on the net.

    My copy of XP IS genuine, I bought it brand new in 2002 I believe. It’s just I’ve had to do so many tweaks and re-installs that I’ve run out of tries. Never even knew that was going to happen; you’d think with a CD it’d be unlimited. SURPRISE!

    Kudos, you’ve saved my bacon!!
