    Windows says my Key is in use on another PC


    I did have it installed on another computer but, it was uninstalled. Do I wait to see If the system needs to gather information or do I need to reinstall? Btw, this is NOT the Inspirion 14z 2013.

    You may have to contact Microsoft to activate your new windows installation.

    Well maybe the key is still associated to the old computer in Microsoft servers.

    There is no explicit de-activation. The activation servers only have the information that the key was used.

    You'll have to activate by phone. The first level is automated. If that fails, you ought to be referred to a human. Even then, the whole process should take less than ten minutes.

    After doing a clean install you must also do a (Refresh) to activate windows 8…

    That's the work-around to activate a Win8 upgrade copy on a hard drive that lacks an OS that qualifies for the upgrade.

    The OP didn't say what sort of Win8 license he (she/it/they) has. I'm not sure, but I'd expect to get a wrong license key type message before getting a key already in use message if an upgrade copy was used to install Win8 on a blank HD (without using the refresh trick).
