There is one solution, purchase from a real source a true-blue Microsoft Windows 7 Professional [for example] 32-64 bit pack. I did that for my two laptops -- hence, there are at least two known laptops that no longer have OEM Windows. Do not purchase from eBay or Amazon. For example, I purchased two from Altex Electronics [Austin store] and one [for my desktop] from Fry's Electronics. Make absolutely certain, "measure thrice," buy once, you are getting a NON-OEM, non-Starter/BuilderPack, a true-blue Microsoft Windows 7 32-64-bit pack; it will be expensive, approximately the cost of 30 packs of cigarettes [so if you smoke, cold-turkey it awhile].
