You know that Microsoft offers the Windows 10 as a free upgrade to everyone running Windows 7 and 8,1 starting June 1st. 
Initially, we all knew that this update was not mandatory and that everyone had the right to choose an operating system.
But it turns out that Microsoft with some corrective changes distributed through Windows Update, no longer allows the user to choose to delay or cancellationof upgrading its operating system.
In other words, your computer can be automatically upgraded to Windows 10 after a restart, because, as reported by ZDNet, Windows Update now offers just one option to start installing the new operating system and nothing more.
Additionally, there are no other updates at this time, so if you do not install Windows 10, you can not do anything other than Windows Update.
What's really interesting is that some third-party apps that could have blocked or delayed upgrading to Windows 10 in the past are no longer working. Rather a recent update made them ineffective.
Josh Mayfield, GWX App Developer Control Panel reports that its app no longer works and can't say for sure if there is another way to make it work.
If you are seeing either of the above two screens, exactly as they appear here, GWX Control Panel is not yet able to help you, although I am looking into whether it's possible to fix these things through software. I do not have any recommendations at the moment, though, unfortunately.
Υπάρχουν ορισμένοι χρήστες, που αναφέρουν ότι τους βοήθησε η Επαναφορά Συστήματος αφού μπόρεσαν να επαναφέρουν το σύστημά τους σε μια προηγούμενη κατάσταση πριν από τις 14 Οκτωβρίου, ημερομηνία κατά την οποία η Microsoft φέρεται να έκανε την change.
What else can you do?
Stop Windows Update. It will prevent upgrading for now, but it is not the best solution as it prevents any download of updates to your operating system.
Use System Restore as mentioned above. It is one of the best choices provided that system restore points are available.
To run System Restore, press the Windows key along with R, type rstrui.exe and press enter to open System Restore.
