I thought that was just to cancel if you originally accepted as Robert Gray did. I never accepted so do I still have to cancel? You said above this will come as an automatic update so even if you don't reserve the "free" upgrade, you will still get it? I guess (as usual) I am confused.
The automatic update (KB3035583) that schedules the download of Windows 10 has been known to sneak in through automatic updates. On some computers it appears as a "Recommended" update and will install through automatic updates without asking you if you want to update or not. It snuck in on my Windows 7 computer as a "Recommended" update, like a Security update. But on my Windows 8.1 computer it was listed as "Optional." But the reverse can also happen, with it being "Optional on Windows 7 and "Recommended" on Windows 8.1.
We had more discussion on update KB3035583 and how to remove it in the other Windows 10 thread
http://www.gameboomers.com/forum/ubbthreads.php/topics/1016941/2The steps for removal are
1. Check to see if KB3035583 was installed on your computer, and uninstall it if it's there
2. Run Windows Update manually and hide KB3035583
1. To see if Microsoft snuck in KB3035583 through your Windows updates, go to the "Programs" in Control Panel (where you go to uninstall programs) and choose "View update history."
If you need more specific instructions, the Sevenforums website has instructions
***here***.
If you see KB3035583 in your list of uninstalled updates, you can uninstall it from there.
2. However it will reappear in your Windows updates. So to prevent it installing again, you have to (temporarily) disable Windows update, then manually run Windows Update (use the Start search to find Windows update). Then check Recommended and Optional updates to find KB3035583.
You right-click it and choose "Hide update." Step 3 in the Sevenforums webpate
***here*** shows how to hide updates.
It can be hard to find KB3035583 in the long list of updates, but you can put them in numerical order by clicking where it says "Name" near the top of the list of updates. However they will still be in separate sections, so you must search all the sections.
