Months after purchasing a XP Pro refurbished laptop I am getting a * in
the tray and wanting to validate. I have used every day for hours.

I tried all the options and they all failed that are presented from the
menu at the * in the tray.

Several of the webpages that get opened are blank.

The main webpage with two options to validate opens ok but both options
fail. Files get downloaded but do not run.

There is a MS tag on the bottom of the laptop.

How do I tell what the tag represents ?

What to do to validate ?

Where do I look in Windows to get the product key ?
