I am not sure what kind of "warning" you expected. Most new software is not built for an 11 year old operating system that is no longer supported by its own creator.
I can only laugh at all of the people who are going to get refunds. What software are you going to buy? No tax software that I can find runs on Windows 7 and most discontinued support for it last year, when TurboTax gave it another year. It will not work on TaxAct, Tax Slayer, or H&R Block.
You need to update your system or use the online option which is the version the majority of folks use anyhow. There is another choice for you aside from upgrading your ridiculously outdated machines.
