deleted hard drive

I was at first delighted to be offered the win 10 download but like many I hate it, I downloaded it to three machines two on win 7 one running win 8.1, the laptop with 8.1 was the first to suffer having its hard drive wiped after a win 10 update, then my pc that was on win 7 pro is suffering from memory and hard disc problems, today the latest to suffer the win 10 curse was my old laptop which recived an update and promptly went to black screen, having made a recovery disc I put it in only to find that the win 10 repair disc isn't compatable with win 10, I attempted to reload win 8.1 to my new laptop but it seems Microsoft will not allow instillation with an OME activation key, on the pc that is still working programs are constantly being deleted I cant get into emails and the system has a mind of its own, turn it off it restarts the monitor revolves from a visable to a blackscreen, nothing will down load unless its from the Microsoft shop?, I phoned windows support only to be told by an idopt in india that I have to turn on a wiped computer to talk to tech support, that one would usually have made me laugh if I was in a better frame of mind. ringing uk support is a waste of time as no one seems to work in the office that has the ability to work out how to answer a phone, I write this in the hope that some one from Microsoft my actually care about their customers and read this and have some answers to how I might recover the life of my beloved computers and give me the ability to once again laugh at indian call center guys called dave, well its good to have a dream lol, I feel for every one who left a working OS to load the WIN 10 nightmare....

In my experience The opposite is true .
I've installed windows 10 on 9 laptops , family and friends . Dell ,Sony , HP , Asus ,Acer and the only issues I had were with activation very early on but that was ignorance on my part as at the time I didn't research properly how to clean install.
I have had a few minor issues along the road but nothing that couldn't be sorted with some patience and research . This forum has been an excellent first port of call .
