I contacted Microsoft Answer Desk a few days ago because I had a problem with certian update namely KB3000850 on my Acer Aspire Switch 10 that has windows 8.1 single language with Bing pre-installed. The technician suggested that she starts a remote session and I agreed thinking she would be able to resolve the issue. She took a few steps and made a few changes and to be honest she tried every possible method she knows and stayed online with me quite long but in vain. The only mistake she made is that she provided to me a link to upgrade windows 10. Here comes the problem. The installation took 24 hours or so to finish and when it is done I found that it wiped out all Acer's services including recovery option and the option to go back to windows 8.1 when all I done is hit upgrade because the setup window has no clean install option. I accordingly had to buy another device since I depend entirely on my laptop for my work. When I bought the new hybrid laptop which is Asus I made a recovery usb to solve the issue. Fortunately, I could get back windows 8.1 by resetting the pc because I could 't perform system restore. The problem is the new windows requires an activation key which I don't have and of course I couldn't get back Acer's services. I also downloaded media creation from Microsoft site but the setup window asked for product key. Another problem is when I tried to sign in to my Asus with Microsoft account the desktop changes to Acer's with all its content even the battery sign that I didn't really know that Asus battery still recharging because the Acer battery was full. I'm sorry for talking too much but I've been struggling to solve this issue the past week. Thanks in advance for any advice.
