I am planing to buy a laptop in the next days most probably with Windows 7 under an OEM license. 1) Do I have the right to ask for a CD for a full install even if it comes already installed? 2) Besides the sticker attesting the validity of the license what I should expect to be given? 3) Any chance that I could ask for two partitions in the HD? Have read lot about this but found not the above details. Question for myself: why all this is always so obscure / obsfuscated for common people?
