Install KB3035583 update for Windows 10 upgrade - Win 7 & 8 users

Initially, I didn't know that people were getting Windows 10 upgrade for free, I found that people automatically got a Windows 10 icon on their task bar asking them to get Windows 10. To get this icon your Windows 7 or Windows 8 OS had to be up to date. I had turned automatic updates off so there was no way my Win 7 PC would quality for the Windows 10 upgrade. KB3035583 is the main update required for the Win 10 upgrade but before that you also need the (2919355) update. So to get these files, I went to windows updates (press start then search "windows update") and then manually checked the latest updates and installed it. I got many "failed to retrieve" error or failed updates but it looked like Windows update skipped installations for old updates and only installed the latest ones. However I could not find KB3035583 in windows update. Luckily, I found a way to install this update manually. If you are a Windows 7 or Windows 8 user, follow the below steps to download the KB3035583 update file, which will let you reserve your Windows 10 upgrade.
