Why do I now have a “Get Windows 10” icon on my desktop...down in the right hand corner?
You have a option to update for free....you can takeitorleaveit...
My assumption:
Signing up gets you in the queue for the upgrade. They are not going to be able to upgrade everybody on the 29th.
If you sign up they will give you a notice when you are able to upgrade.
Yur blessed .. you have a approved slot to get it before a lot of other folks..
