I am not trying to be lazy, and have read most of the threads, but cannot work out what to do. I know that maybe there is no benefit in using 10 at the moment, but feel I ought to try and keep up. I would install it on an old PC which is powerful enough, but not my main machine. I always use KILLDISK to wipe all drives before starting any install. I then set BIOS to SATA as none of my PCs seem to recognize the install disk/ISO in UEFI mode. I have not grasped the real differences but seem to make it work if BIOS set to SATA. I would like to use the GB 32 bit mode and can cope with an ESD file or ISO file. Looking at the links, one is offering a download called 10074.0.150424-135.fbl (a load more).ESD - (shortened to save time) 1 - Is the above file the correct one to use? - I am not trying to be clever, and only need the basics. I do not use any games, but normally just Chrome, Office 2013, Photoshop 6 and my old DOS database. 2 - Do I need a key to install? - I find with 8.1 that on my laptop I had to use the generic key, and was then able to use my legal key, retrieved before wiping disk to activate. 3 - If so is it easy to find the generic key? - a pm would be very helpful if this is required Do I then activate using Windows Toolkit 2.51? I think that these are the only questions I need to be answered. I would be very grateful for a simple answer. I have terrific respect for the posters on the forum, and I find it quite difficult to keep up. I feel lost on Windows 10 and do not want to fall further behind. Many thanks in advance.
