Screw Win8, it's complete garbage for a desktop IMHO.

Why use Windows 8 "for one month", when you can do the same with Windows 7?
Just be aware: If you do so, you can't use Windows Update because your installation is not activated. So to at least get the most important security updates, use this program: http://www.wsusoffline.net/

Wrong. Windows Update service works totally fine if you installed Win7 without any key into 30 day trial mode.

If you're 100% sure you're going to buy Win7 within that 30 days then using it in the trial mode is totally valid option, just make sure you'll install the version you're going to buy later.

If you aren't 100% sure it's better to get Win8 release preview which won't expire for another half year at least. That'll give you a) plenty of time to sort your money, and b) plenty of time to get used to the new version and not want to downgrade it later.
