Have Win10 running on a new build with few issues. On another computer (Win 7) I have the upgrade window in the tray and I never said yes to Windows 10. I noticed that Windows update had a download for me ( Win 7) so I opened it. There was Windows 10 waiting to download. But it needed administrative permission to download and install. I noticed a blue bar and I clicked on it to see what was in it. There were a list of files including security files. I checked those and only those. I DID NOT check the file related to IE 11. I did not give it administrative permission to download or install.
Later that day a third party security app needed to update and then asked to reboot. I felt secure and rebooted the computer. The downloads in Windows were very slow. I went about my business and returned just to see Accept or Decline. I quickly declined and Windows quickly removed two files ( updates). I stopped it in it's tracks. After another reboot I checked Windows update and found that the two filed were clearly labeled Windows 10. They are waiting!!!!!!
