there was an issue when sp1 was first released but that didn't show as "build 7200"
It typically came up as "Build 1702" and misidentified Legitimate windows 7 installations
as expired "Windows 7 Beta"
Ok, from what you've already provided this sounds like the following:
1) Sometime in the last 30days or more you installed windows 7
2)Automatic activation failed.
3)You did not manually activate.
Turn your computer back on when it offers you the option to "activate windows now" choose it.
It may offer you a change to enter your "Product Code" (also known as "a CoA or "certificate of authenticity" which is five blocks of five characters, a combination of numerals and capitol letters.
Your windows installation disc should have come with a sticker OR is this is a recently purchased computer the sticker will be stuck to the case.
Re-enter the number carefully (or check the number that's already entered)
If this attempt at "activation fails" you will be presented with an option to enter another product code
BUY another product code or call an automated phone line, choose this last option
you then get to choose your country, after doing so you get another page where there is the phone number and at the bottom there are eight blocks of six numerals each and below that eight empty blocks.
follow the voice prompts and enter the numbers with the keypad of your phone
it may then ask a verification question (example: How many computers have been installed with this copy of windows? (generally you answer "One")) and after it pauses a minute the voice will say "verified" then read you eight blocks of six numbers each that you must type into the empty blocks.
I've found that if you enter a number wrong it'll stop you, unless you enter a number wrong in the last block and then you really do need to start over.
But you have an option to "start over" and I usually do this to hear the numbers over again to verify I typed them correctly
If you don't get an error message after pressing "next" you are golden...
Basically follow the instructions and avoid human intervention at their end
the automated system works, the humans will always insist that you need to buy something....
You Do have a CoA/Product code... right?
You DID buy your windows legitimately... right?
