If you buy the cheaper "Upgrade" version of an OS such as Windows, do you have to install the older OS each time before installing the newer OS, or can you install the new OS directly? If the latter, how do you prove that you have the older version? Does installing one OS over an older one slow down computer performance?
Also, can a laptop change OS's? Or do the drivers provided only work with the OS it was packaged with.
