While it is true that Beta products can have bugs, I have been running Windows 7 beta for months and have had no problems with it, I do
care about my computer and have no problem running beta if from a company I trust.
I back up my important files regularly and actually like to wipe my system clean about once a year ( complete format and reinstall).
this product is FREE until the expiry date passes and then if I choose to purchase the full post Beta product I will.
You will not lose everything, you will only lose the ability to use this product.
So again I thank you OP for the heads up!
That said downloading and using any Beta product is not for those without some Tech knowledge and the faint of heart
