    Hi there, i read your blog occasionally and i own
    a similar one and i was just curious if you get a
    lot of spam comments? If so how do you protect against it, any plugin or anything you can recommend?

    I get so much lately it’s driving me crazy so any help is very much appreciated.

  6. Greetings from Florida! I’m bored to death at work so I decided to check out your blog on my iphone during lunch break. I love the information you provide here and can’t wait to
    take a look when I get home. I’m amazed at how quick your blog loaded on my mobile .. I’m not even
    using WIFI, just 3G .. Anyways, superb site!

    Uninstalling Your Product Key

    The first thing we need to do is get our activation ID, to do this fire up an administrative command prompt and run:

    slmgr /dlv

    Windows will open a message box and tell you a bunch of information about the license status of your PC, take note of your activation ID.

    To uninstall your product key you need to use the /upk switch, along with your activation ID:

    slmgr /upk activation ID
    slmgr /upk 507660dd-3fc4-4df2-81f5b559467ad56b

    If you do it correctly you will be told that your product key has been uninstalled.

    Installing Your Product Key

    Installing your product key on your new PC is just as easy, all you need to do is fire up an administrative command prompt and use the /ipk switch.

    slmgr /upk new key

    If your key is valid you will be told that your key was installed.
