The general consensus seems to be that as long as you keep your security (anti-virus) up to date then there shouldn't be any immediate problems. I tell my clients they have a few months to a year.

A more inexpensive solution might be to see if your computer can run Windows 7. Purchasing the Win 7 program is around $120 for the basic one around here. Note: You will have to back up all your files before reinstall, and find out what the product key is for your version of Microsoft Office. There is a great free office program called LibreOffice: https://www.libreoffice.org/download/libreoffice-fresh/

You will still be able to obtain security solutions from companies including Norton, AVG, Trend Micro, and Kaspersky. It will depend on the exact company, but some are promising to continue providing support as late as 2019.
