Problem with windows activation

Hey guys i found a key for windows 7 i typed it in it worked and when i restarted my pc it was all fine but when it powerd back on it said test mode windows 7
Now i downloaded a windows 7 fixer and it updated my licence and all that and it all seemed to be fine but i restart it has an 3 min update then when i log on it said it need to be activated again and says windows 7 test mode in the corner any help?
Thanks stormz

1. A genuine Windows DVD would have its own genuine product key.

2. "Finding" a product key for Windows suggests dodgy software.

3. Discussing pirated software is against the rules of this forum: see Rule 4.
