If you are still running Windows 7 or 8 you may see this screen.
Sorry to interrupt, but this is important.
Your PC is running an outdated version of Windows 7
You can still upgrade windows 7 and 8 for free.
(Its recomended that you backup your computer before you do this update and if you have any software ensure that you have the installation files and licence numbers to reinstall just in case there is a problem. Most installations are successful but its better to be safe than sorry not to mention the fact that you should always have a backup and if you dont this is a good time to begin. The old dentist joke applies here, “Only floss the teeth you want to keep”)
You can still upgrade to Windows 10 by going to this Microsoft link,
download the Tool and then run it.
