gripe, gripe always gripe when it comes to Microsoft ...... I installed windows 10 on our laptop FOR FREE, try that from Apple(cart). The laptop no runs like a charm well it did it in win 8 and 8.1, too. I have hade microsoft since dos and I still have my disk for dos 3.1 and all the ms windows. yes i have tried all of the other OS, but always come back to Microsoft be cause I think they have produce the best OS and they still do. I have used MP-80, TOS(Atari), Android(tablets), iOS(tablet), redtop and about 5 different, IBM window(came out just be for wind95) and so many other so I think I know little about them OS. have worked with computer since 1983 build my first computer in 1992. I like to say stop griping and have fun or if you don't like the MS products go and use an other OS.
BTW Microsoft have neer send out a OS with a serious virus like Apple have done.
