A small SCHIFOSISSIMO system file just 78 Kb I did install version core professional and Windows 8. For two days I turned to the internet and no site I was able to find this file. The name is STORAHCI.SYS and should reside in system32\driver, but those who do not take goes into the hole and failed to install these versions that Microsoft is giving free and precisely because it is free I don't see the need to discourage the user putting in head doubts about his ability to be able to install these system versions. What happens if you do not have this file, a BEAUTIFUL BLUE SCREEN ASKING YOU to RESTORE the SYSTEM because IT LACKS THIS DAMN FILE. Do you know where I found the offending file???? just in one of those versions and was placed alongside other peers that are on your computer, but no. Microsoft has chosen to use this file without which you cannot install but to terrorize the clientele ... but not a good choice for ME. Finally the question: How do I read the S.O.?? and is this the right thing to do??? Thanks for your help!!!!!
