I don't know for sure but I assume that win 7 is next gen DRM and cracking isn't an option. Your obviously running the original beta which starts timing out in june I think and shuts down in july. Why not just get a copy of the RC (release candaite); its good till august 2010.
Or you got till July 15th to buy Windows 7 on a place like Amazon. Com for $50 bucks or $100 (Premium & Professional respectively). It doubles in price for the upgrade after that.An upgrade means you just need a serial from XP or Vista.
Your best option is to upgrade to the Windows 7 Release Candidate. It will not expire until the middle of next year. You should be able to download it from the same place you got the Beta.
However, you will still have to do a reformat/reinstall, because Microsoft does not allow you to upgrade directly form the Beta to the RC.
Download the free release candidate, which will be good until next year.
I cant really gove you an answer,but what I can give you is a way to a solution, that is you have to find the anglde that you relate to or peaks your interest. A good paper is one that people get drawn into because it reaches them ln some way.As for me WW11 to me, I think of the holocaust and the effect it had on the survivors, their families and those who stood by and did nothing until it was too late.
