A few of our clients have some old Windows 7 and other older versions of Windows and have no plans to upgrade them. What is happening is that Microsoft is starting to send them advertising messages that they are out of support. These will not stop, in one form or another, I expect that every one of these older computers to keep sending you this message. It can get irritating as you have the word already how long does it keep having to be repeated?
If your planning is to stay with Windows 7 on some computers, this here is how to get rid of these messages.
