You can still upgrade, at zero cost, to Windows 10 by using the ISO media downloaded with Microsoft Media Creation Tool. Make a full drive image, so you can restore properly if it hiccups. unplug any USB devices. Plug in a USB stick made with the Media Creation Tool, ,or even use a DVD of v.1809 that matches your machine 32 or 64 bit. Run setup.exe. You will be upgraded to Windows 10. I suggest that you do not uncheck the check for updates box. You need to insure maximum compatibility by having Win 10 only install what your machine needs for drivers. Only incompatible programs will be removed during the upgrade. There won't be many. Probably nothing will be removed.. Any that are can be reinstalled using compatibility as Windows 7, without a hitch. I do this to several customer machines per week. When setting it up, move all seven slides to No. You'll see what I mean when you see that screen. Also, don't use a Microsoft account, unless you want to sync multiple machines. On the lower left corner, choose Use a local account. The next screen will ask if you're sure. Your machine is worth keeping running, as long as it meets your needs.
Third party anti-virus programs often slow down Windows 10, and are unnecessary. All our machines have been built with only Windows Defender as the AV program for the past 15 months.
