  • Hi Kapil. Great explanation. But none of these has worked for me. I’ve made sure antivirus and malware software is off and also freed up space on C:
    I’m hoping there are other options apart from installing the ISO….any ideas would be gratefully received.

  • It’s 2016 now, and the free upgrade is due to expire in less than 29 days, judging from the numerous inquiries about the modern setup host stopping, I would assume that Microsoft is very aware that there is a problem!
    My guess is that they want people to give up in frustration and buy a copy of Windows® 10, or else they would have certainly addressed the issue by now.

    ^^ They are aware of this problem. I believe this might be resolved by Anniversary Update: http://www.kapilarya.com/windows-10-anniversary-update-expected-to-arrive-this-july

  • My comment is the same as Tammy Tamponski….Tried the above solutions and still get the error message. My Windows 7 is working fine, to heck with Windows 10.., Thanks Microsoft, guess I was one of those selected who will be required to pay if I ever want Windows 10 on this computer. Also does the same on one other computer we have… maybe they go by our address.
